In this tutorial I will demonstrate how to enable and configure Exchange Server 2010 Outlook Anywhere to provide secure mailbox connectivity for remote Outlook users.
Outlook Anywhere is a much better solution for remote email access than POP or IMAP because the end user experience is the same when the user is using Outlook on the LAN or remotely. Thanks to SSL encryption Outlook Anywhere is also inherently more secure than other protocols that have non-encrypted options that companies often deploy.
What is Outlook Anywhere?
Outlook Anywhere is a service provided by the Client Access server role that allows Outlook clients to make a secure connection over SSL/HTTPS to the mailbox from remote locations. Previously this was known as RPC-over-HTTPS but was renamed to Outlook Anywhere in Exchange 2007 and 2010.
By wrapping normal Outlook RPC requests in HTTPS the connections are able to traverse firewalls over the common SSL/HTTPS port without requiring the RPC ports to be opened.
There are three main tasks to deploy Outlook Anywhere in an Exchange environment:
- Enable and configure Outlook Anywhere on the Client Access server
- Configure the perimeter firewall to allow SSL/HTTPS connections from external networks to the Client Access server
- Configure the Outlook clients to use Outlook Anywhere when connecting from remote networks
Enable Outlook Anywhere on Exchange Server 2010
In the Exchange Management Console navigate to Server Configuration -> Client Access, and select the Client Access server you want to enable for Outlook Anywhere.
If you have multiple Client Access servers in an Active Directory site then choose the one that is the internet-facing Client Access server. Or if you have deployed a CAS array you will need to repeat this process on all members of the array.
With the server selected, in the action pane of the Exchange Management Console click on Enable Outlook Anywhere.
The Enable Outlook Anywhere wizard launches. Enter the external host name for Outlook Anywhere users to use when connecting remotely to Exchange, and choose an authentication method.
The external host name you choose should ideally be one that is already included in the Exchange certificate configured on the Client Access server. Otherwise you will need to create a new certificate for Exchange.
The Outlook Anywhere authentication method you choose will depend on a few factors in your environment.
- Basic Authentication – this requires that Outlook users enter their username and password each time they connect to Outlook Anywhere. The credentials are sent in clear text so therefore it is critical that Outlook Anywhere connections only occur over SSL/HTTPS. You may need to choose Basic Authentication if the connecting computers are not members of the domain, if the ISA Server publishing rule and listener are shared with other Exchange services that require Basic Authentication, or if the firewall being used does not support NTLM authentication.
- NTLM Authentication – this is ideal for connecting clients that are domain members because the username and password will not need to be entered by the user each time they connect. However NTLM may not work with some firewalls or ISA Server publishing scenarios.
When you have configured the Outlook Anywhere settings click Enable to continue, and then click Finish to close the wizard.
The Outlook Anywhere configuration for Exchange 2010 will take effect within 15 minutes of completing the wizard. The Application Event Log will record Event ID 3008 and a series of other events when the configuration has been applied to the server.
Configure the Firewall for Exchange Server 2010 Outlook Anywhere
To enable remote Outlook users to connect to Outlook Anywhere the perimeter firewall for the network must be configured to allow the SSL/HTTPS connections to pass through to the Client Access server.
The precise steps for this will depend on which firewall you are using in your environment. However the basic components of this configuration are:
- A public DNS record for the external host name you are using for Outlook Anywhere
- A public IP address on the firewall that the public DNS record resolves to
- A NAT or publishing rule to allow SSL/HTTPS connections to reach the Client Access server
If you are running an internet-facing Exchange Server 2010 CAS array then you would configure the firewall rule to direct traffic to the CAS array IP address.
Configure Outlook Clients for Exchange Server 2010 Outlook Anywhere
Before an Outlook client can connect to Outlook Anywhere it needs to be configured with the correct settings. In Outlook 2010 open the Account Settings for the Outlook profile that is configured.
Double-click to open the properties of the Exchange Server profile that is configured.
Click on More Settings, and then select the Connection tab of the settings dialog box that appears.
Tick the box to Connect to Microsoft Exchange using HTTP, and then click the Exchange Proxy Settings button.
Enter the External Host Name that was configured for Outlook Anywhere earlier on the Client Access server, and then configure the Proxy Authentication Settings to match the client authentication method chosen on the server.
Click OK, OK, Next and then Finish to apply the change to Outlook 2010. You must restart Outlook for the new settings to take effect.
Now that Outlook 2010 has been configured for Exchange Server 2010 Outlook Anywhere, any time the user launches Outlook from a remote connection and can reach the perimeter firewall over the internet they will be able to securely access their mailbox as though they were still on the corporate network.
Hi Paul,
We have Similar situation to this. I have EX2013 configured initially with server FQDN in Outlook Anywhere URL (server.domain.internal) and other services as well (Autodiscover, OWA,EWS) with self signed certificate.
Now we have deployed a new certificate to reflect mail.domain.com (Along with Autodiscover.domain.com) as SAN name in it.
After deploying the certificate (Still the URL’s pointing to server FQDN), outlook clients started displaying certificate error.
We have changed the URL’s to match the SAN name in certificate (mail.domain.com)
Do we need to reconfigure the outlook clients again?
We see still clients connects to old URL and showing certificate error, however Auto discover test connects to new URL.
Note: Creating New profile works fine. However old profiles still displays certificate error.
Hello Paul. Great article. Can you please write an article on MAPI over HTTP in Exchange Server 2010 & 2016. Whether we can use MAPI over HTTP in Exchange Server 2010. If we can will it work with Outlook 2010 SP2, 2013 & 2016.
Please note I am using exchange 2010 and outlook 2016 to test this
Despite the above the test succeeds. What am i missing here? I get multiple authentication prompts as well when i am configuring outlook anywhere from external(meaning outside my LAN) . my autodiscover is in SSL certficate
You should probably try a network trace with Fiddler or a similar tool so you can see where the client is connecting. Or open a support case with Microsoft.
Hi Paul
While running test connectivity i get
The Microsoft Connectivity Analyzer can only validate the certificate chain using the Root Certificate Update functionality from Windows Update. Your certificate may not be trusted on Windows if the “Update Root Certificates” feature isn’t enabled.
Elapsed Time: 2 ms.
It means that machines that don’t have the latest root certificates might not trust your certificate. It’s just a warning that mostly impacts older machines or those that don’t allow root certificate updates.
Hello Paul,
Great article and appreciate your effort to avail this for intermediate and fresh Admins 🙂
may be its quite simple question but still want to double confirm, lets say if i change OA url, will outlook clinet affects?
there will be two scenerio as per my understanding,
1. what will happen with outlook clinet which is configured using autodiscover?
2. what will happen where profile is been configured manually?
Thanks in advance!
Outlook clients will receive the new URL via Autodiscover. It will only impact Outlook Anywhere connections. On the LAN, Outlook uses RPC/MAPI to connect, not Outlook Anywhere, so they won’t be impacted unless you’ve got the config in place that forces them to use Outlook Anywhere all the time.

What if I want to use outlook 2016 with Exchange 2010. where can I set the HTTP settings as it doesn’t have connection tab. ?????
Paul, I am having an issue with attachment downloads where the root cause is hard to identify.
Download of attachments in the Wi-Fi network takes up to 40 seconds. Download through LAN works without delay.
Same issue on different hardware with the same user.
OWA download works both ways, LAN and Wi-Fi without delay!
Download via Outlook Anywhere also works without any delay.

Good afternoon, is there a report to run concerning who is actually utilizing Outlook Anywhere?
I have setup Exchange 2010 server – all working fine inside the organisation.
I am trying to configure outlook 2010 to use the imap/outlook anyware accounts on exchange 2010, but can’t access these remotely (outside the office network).
I know I could use OWA, or exchange with RPC, or even a VPN – but I would like to use IMAP as I have around 10 email accounts, some on different domains, that I need to check regularly / at the same time.
I have the correct ports open on your firewall to allow IMAP traffic to pass through to our exchange server .
while I telnet with public ip address the port 143, 993, 110 its connected and ready.
Can anyone advise on how to setup exchange 2010 / outlook 2010 that I can access the imap account remotely using outlook 2010.
Thanks
Hi Paul,
We are running on Exchange server 2010.We are connecting to outlook through RPC over HTTP and no MAPI enabled. We are facing intermittent issues with Outlook connectivity. All the user are connecting from internal network only. We ran EXRCA and did not find any issues except”Checking the IIS configuration for client certificate authentication.Client certificate authentication wasn’t detected.” Need your help in identifying the issue and troubleshoot it. I am not getting where to start to digging into the issue. Can you please assist/help me in resolving it.
Does the Outlook Anywhere namespace resolve to an internal IP or external IP for clients on the internal network?
If it resolves to an external IP maybe your firewall is dropping the connections. Or there could be any other possible network issues between your clients and the server (firewall, load balancers, WAN links, virtual network config….)

Hi Paul,
How does Outlook 2010 clients connect to Exchange 2013 SP1. Does it connect through RPC/Http. Does exchange 2013 SP1 support rpc/http connections. Thanks.
Correct, it is via Outlook Anywhere, also known as RPC over HTTP (or HTTPS).

Hello Paul
Thanks for the article, it’s very useful.
I am having an issue, though. After configuring Outlook Anywhere, with proper SSL certs, the Remote Connectivity Analyzer gives green light. However, when I configure Outlook (2013) it never wants to successfully connect and it keeps on asking me for the username and password. Now I am connecting from a different domain as the Exchange(2010) server is in, theoretically (if I understand correctly) this shouldn’t matter if I use basic authentication, right?
However, even with basic authentication I can see in the server’s log that the authentication fails and it shows the incorrect domain name under the account name. How can I prevent this from happening?
Thanks, kind regards.
OK found it, it appeared a DNS entry was needed on the Windows server pointing the external host name to the internal address, for that a split DNS configuration needed to be created. Now it works…
I used this article http://www.petenetlive.com/KB/Article/0000830.htm.
Thanks, kind regards,
Jaap
Dear Paul,
Can we disable outlook anywhere auto configuration in client side as we disabled manually after restart it is enabling auto.

Hello Paul,
Thanks for your tutorial, it makes life easier, Exchange server and OWA had been working fine till yesterday when adding firewall. Following the ports defined on Microsoft website, lots of ports had been added for firewall. Clients can access mail by using outlook from their computers outside company. However, they cannot use OWA to access it, the main page of OWA can be shown, but when users type correct user name and password then click login an error page came out shown in the following
The web page is not available
The web page at https://webmail.abc.com/owa/auth.owa might be temporarily down or it may have moved permanently to a new web address.
Error code: ERR_RESPONSE_HEADERS_TRUNCATED
We are using dedicated server and firewall is provided by hosting provider. They said
It was adding the internal IPs to the nic. You need to make sure that any applications using the public IP are swapped for the internal IPs.
I would like to ask you how to address the problem and what kinds of problems would cause it?
Had checked that ports 80 and 443 are open to inbound traffic
Many thanks
Simon
Hi Paul,
i have the Problem with RPC over HTTPS with the Message Limit. When a User connect the Outlook from extern the Synchronisation is starting and everything ist fine. When i send a Mail with 15MB Attachement the Synchronisation stops at 10MB an will not start again.
I think there is a Limit at 10MB for RPC, but where can i Change this?
All other Limits (Send connector, receive connector, etc.) are configured to 100MB this time.
Have you a reason for this Problem??
Hi Paul,
the Computer isnt in the Company Domain. This Computer is a Little Workstation for the Directing Manager in his own Holiday Cabin in the Alps in Austria. Hi dont want to connect this private Computer to the Domain, why ever. As Firewall in the Company we have a Barracuda Firewall with no Limits for this Protokoll. On the Firewall we see that the Stream is disconnect on 10MB but we see no reason.
Hi Paul,
I had configured Outlookanywhere as per the steps provided.
Got a SSL certificate from Godaddy and made Common name same as the one provided in outlookanywhere .
The first time when i configure a profile outlookanywhere is connected and the user is able to send/recieve,but when he closes outlook and open again,exchange proxy url is changing to internal CAS server name and outlook shows as disconnected,If we change the proxy to external url.he is able to send/recieve..
Iam using basic Authentication for outlookanywhere.
How do I fix this?
Appreciate your help in advance.

Hi Paul,
I had a query regarding Authentication Settings on CAS 2010.
Can we offload the Authentication to another Network device on CAS 2010?
Description of my issue:
I want to authenticate user on my Network Device and once they are authenticated
I redirect them to the CAS server.
I do not want the CAS Server to re-authenticate the user. Currently it does.

You need a device that can do pre-auth. TMG was one such solution. Kemp’s ESP is another.

Can you help, please?
What do i have to configure to support multiple outlook anywhere External host name’s or URL’s with single Exchange 2010 site?
e.g. webmail.domain.com, Outlook.domain.com, email.domain.com
Can i run like this
Enable-OutlookAnywhere -Server ‘CASarray’ -ExternalHostname ‘webmail.domain.com’, ‘Outlook.domain.com’, ‘Email.domain.com’ -DefaultAuthenticationMethod ‘NTLM’
Thanks in advance
A Client Access server (not array) can have one external Outlook Anywhere namespace.
Hi Paul.
Have to say all of your Exc step by step procedures are awesome.
Keep up the good work. I use a lot of it religiously. hehehe
Please advise. Currently i noticed that random users are suddenly being prompted for passwords whilst on the LAN. further look shows that outlook is trying to connect to my webmail server and that’s what is requiring the Password.
On my exchange 2010 box i currently have CAS authentication set to basic and not NTLM.
If i do set5 this to NTLM does this mean that users connecting from non domain PCs such as your mobile phones and PCs at home; will not be able to connect.
Strangely it has always been on basic but this problem has only come up a few months ago 🙁
If i set those outlook clients to use KERBEROS it solves the problem whilst others work fine on NEGOTIATE AUTO. Reason for Kerberos is i have riverbeds which require mail security to be set to that security level….
Non-domain clients should still be able to auth when it is NTLM.
From memory though, the auto-logon can stop working if the Outlook Anywhere namespace is not in the trusted or intranet zone in IE, or a zone that allows auto-logon. Been a while since I had to look at a scenario like this though.
thanks you for the input but i am still stumped with this issue.
Whenever a users PC prompts for a password; i noticed that at that moment the outlook client is trying to connect to my webmail server.
But the users are on the LAN. how do i tell outlook to use domain credentials for webmail connection over the LAN.
So that it does not prompt users for a password when it suddenly tries to connect to the webmail server
Paul,
What if the goal is for non-domain computers to NOT be able to access my environment? Can that be done at TMG level? A firewall perhaps? Would like to hear some ideas/hear your thoughts. Thanks.
Thanks for the article. The Outlook 2010 client is making a connection and sending/receiving email. If I reboot and start Outlook the settings under Outlook Anywhere have been cleared. I reenter them and Outlook connects. But if I reboot they are gone.

Hi,
to publish outlook anywhere does we need to purchase a public certificate mandatory ?
or an internal certificate enough to do the job ?
and thanks
I have this issue: published exchange 2010 on Cisco ASA 5505 with static NAT port 443.
NTLM auth. doesn’t work for non-domain computers. When I turn on basic authentication, username and password window drops out but still can’t connect. checked on testechangeserverconnectivity and only SSL problem occurs but i have my own CA and i install exported certificates on non-domain devices so that shouldn’t be an issue here. Besides installed CA certificate on my windows mobile and it started to work just fine.
any suggestions?
i have done everything as stated in the article but still outlook anywhere cannot work, however i am able to use owa on both external and internal cleints
Go to https://www.testexchangeconnectivity.com/ and run the Outlook Anywhere test.
Hi Paul,
When I activate Outlook Anywhere on my CAS Servers, all 2007 and 2010 Outlook have automatically checked the Https parameters in their configuration. It’s not a problem if it’s work well every time, but sometimes and i don’t now why yet, Outlook ask password to the user evenf if he’s connected to the domain LAN.
EveryDay i have 1 – 5 users calling us for that, they relaunch Outlook and it works again.
Note : from Wan it’s working fine.
I’am hesitating to disable Outlook Anywhere on CAS, Outlook’s configurations will follow my lead or will I be contact by 500 users ,
Thank you Paul,
Always I am Luck with your Articles.

how are you? Hope you are fine, now I am facing 1 problem relate to configure exchange sever not configured why?
Hi Paul,
Let me add some more information. My exchange 2010 has a self-signed certificate. The internal exchange server name is what is contained in the self-signed certificate and the owa name is different from the internal name.
Could this be reason why when configuring outlook anywhere I get error code 10? I urgently need your assistance
Hi,
I find this write-up very educative. I have configured exchange, but cannot get outlook anywhere to work due to the certificate. If I could get to chat with you live on skype or google chat, that will enable me to get realtime questions across so you assist me set it up.
I will be most grateful
Try this:
http://blog.ronnypot.nl/?page_id=434
Best secret I found in doing this is either create profile and resolve name on the LAN first or via VPN. Set up Mail Profile from Control Panel -> Mail (32 bit). Create profile and follow wizard, except check box for manual setup and use INTERNAL Exchange Server name, and “Check Name”. (This is when you would need to connect VPN first, if you’re not on the physical LAN.) When name comes back underlined (successfully resolved), go to More Settings button, and proceed to the tab to set up Outlook Anywhere proxy server (remote.yourdomain.com, in the case of SBS 2011 default.) Leave the LAN or disconnect the VPN and launch Outlook. You should be prompted for a login (domainusername format) and password. If this is your first time connecting Outlook on this machine, it’ll ask for your name and initials, then “preparing mailbox for first use” and so on until you are looking at your mailbox, FROM the Internet, no VPN required. Everything else in the original article is rock solid helpful. Thanks Paul!
Thanks a lot CBlue , that really helps me. But my main problem now is the EXTERNAL Exchange server. How to set up External exchange server? What exactly do I need is how to create this and its requirements.
Thanks again
Well, I believe the original article here deals with setting up the [external] Exchange Server. My comment was more towards the SBS 2011 Standard (Small Business Server 2011), which has a sort of ‘integrated’ Exchange Server, and is often left out of discussions on on Exchange Server (or Windows Server 2008 R2, on which it’s based.)
Hi CBlue, can you please give me the link of your tutorial regarding integrated exchange server. I’m still studying on how to set up Microsoft Exchange Server 2012. I’m still figuring out what will be the requirements in hardware,software like exchange server and active directory. Thanks
Hi CBlue in your reply regarding outlook anywhere you indicted that after connecting to the network and setting up the profile with outlook anywhere configured that you could access your mail without vpn, just an internet connection that you would be asked for logon credentials and then it would open. I am using a profile with outlook anywhere for the first time my computer was on the company network, configured for outlook anywhere, when I try to open outlook I am prompted for my domain credentials but it doesn’t let me in because it can’t authenticate me because I am not connected to a domain. How is this suppose to work? If I cancel the login then I am working with my offline folders only. I am trying to understand the advantages of outlook anywhere but I don’t understand it is suppose to work.
Thank you,
AlyceO
Make sure that it works on the LAN first, and is configured to use the Exchange server on the LAN. THEN, set up for Outlook Anywhere proxy server (“remote.yourdomain.com”, in the case of SBS 2011 default.) in the “More settings” go to the “Connection” tab and click the Exchange Proxy Server button and follow the original directions to set up your publicly accessible and named Exchange Server in the url box, and pick NTLM as authentication method. Should work at this point. Test it as follows: leave the domain, Launch Outlook, while connected to the Internet. Should be able to traverse the firewall and talk to the [Exchange] server at this point.
CBlue it does work on the LAN, but our admins have us use Basic Authentication, not NTLM. I think I know what the issue maybe I will try that. Thank you for the information.

Hi Paul,
I need help. What are the requirements in setting up a outlook exchange server 2010? Such as; server (physical), domain (paid) and software…
Thanks in advance
Hi Paul,
If you have FBA enabled on your TMG listener and OA is configured for NTLM, i believe i wont be able to authenticate through TMG. For some reason, the MS whitepaper implies that if you have a FBA Listener you will have only Basic Auth delegation available for OA.
In my case FBA listener works with my OA rule only if i pass through TMG by configuring the Authentication delegation to No Authentication but clients may authenticate directly.
I would like to keep FBA on TMG and NTLM on OA for my domain users, but this causes issues with the OAB (web-based) download when passing through TMG, causing a credentials pop-up box.
Any ideas?

Great article and helped me to setup my outlook anywhere deployment
Can you help, please?
What do i have to configure to support multiple outlook anywhere email domains with single Exchange 2010 site?
e.g. webmail.domain.com, webmail.domain2.com, webmail.domain3.com
Can i run like this (or to this effect via another configuration methods)?
Enable-OutlookAnywhere -Server ‘CASarray’ -ExternalHostname ‘webmail.domain.com’, ‘webmail.domain2.com’, ‘webmail.domain3.com’ -DefaultAuthenticationMethod ‘NTLM’
Thanks in advance.
