Microsoft to Retire Old Exchange Admin Center in Office 365 Next Year

Microsoft plans to retire the now-decrepit and very old EAC on September 1, 2022. The old console has hung on too long, perhaps because Microsoft hasn't progressed the development of its replacement as quickly as they could have since its 2019 debut. Although Microsoft claims that the new EAC reached feature parity with the old some time ago, any examination of the two consoles proves that this is not the case. With that in mind, it seems like Microsoft has some work to do to make everything ready for the big retirement date in 2022.

Microsoft Forces Move from Azure AD Cmdlets for License Management

On June 30, 2022, Azure AD and Microsoft Online Services cmdlets will stop working for license management. The result is that you need to upgrade PowerShell scripts which use these cmdlets.

How to Convert Azure B2B Guest Users to Members While Maintaining User Collaboration

Azure B2B guest accounts are often created during a Merger & Acquisition, so teams from both organizations can easily collaborate during the business and technology integration. However, these external users with B2B Guest accounts in their directory will eventually need to be migrated, which is problematic since B2B Guest accounts aren’t recognized as being licensed. The guest account can be removed and a new one created, but previous permissions would be lost. So how do we preserve permissions, keep collaborating without managing two sets of credentials while preparing the user account for data migrations? This article walks you through a solution that can be used in certain situations to help you easily manage the account to meet your needs.

Why can’t you remove the last Exchange Server?

So, you've completed your migration to Exchange Online. Email flows smoothly into and out of the cloud, and all your mailboxes are now online. What's next for your Exchange Servers, now that you've made the transition? After completion you will have several tasks to perform to remove Exchange Servers from your environment, but there is one important caveat you need to know about; if you run Azure AD Connect then you can't remove every Exchange Server from your environment. You will need to keep at least one around for management purposes. In this article, I'll walk through what you can do to minimise what you keep and need to maintain, and what you can consider planning for in the future.

How to Control Sending Email to Teams Channels

If allowed by your organization, you can send email to a Teams channel. Teams uses the email to start a new conversation and this is a great way to get a debate going about something which first appears in email. Managing the Teams email integration features isn't hard. You can define domains to accept email from and enable or disable the feature. After that, it's up to team members to use the capability. Hopefully, they'll resist the temptation to remove email addresses from channels, which is something which should be limited to team owners.

Exchange Online to Enable Plus Addressing Everywhere in January 2022

Microsoft has announced their intention to enable plus addressing across Exchange Online in January 2022. Plus addressing is a good capability, but it might cause some problems for tenants with mail-enabled recipients that have plus addresses in their set of proxy email addresses. Fortunately, we've written some PowerShell code to report those pesky addresses and to remove them if you want to do a big clean up before Microsoft makes the big switch in five months' time.
