A new Exchange Online feature allows users to send email using any of the SMTP proxy addresses assigned to their mailbox. An Outlook update will make the task easier, but for now it's reasonably straightforward to insert a proxy address into the From field when composing a new message with OWA or Outlook and send a message.
Exchange Online has a new domain expiring soon alert, which means that a mail flow insight checks for soon-to-expire domains in the set of accepted domains for a tenant. When the insight detects a domain due to expire within 90, 60, and 30-day windows, it sends a high-severity alert to the tenant administrators to tell them that they should renew the domain(s).
Hybrid hasn't changed much - but everything around it has. Over the last few years small changes to the way people deploy Microsoft 365 along with bigger shifts in the way your secure Microsoft 365 mean your old assumptions about Exchange Online migrations have to change. Has SharePoint become the go-to technology in Microsoft 365? Has HAFNIUM made publishing Exchange for Hybrid migrations more difficult? And how can MFA impact your once seamless migrations?
Microsoft Exchange and security experts answer the top seven questions around compromise and mitigation for the HAFNIUM Exchange Server 2010, 2013, 2016, and 2019 exploits. The Q&A was pulled from an intense, hour-long panel discussion that covers this topic in-depth.
The Hafnium attack on thousands of on-premises Exchange servers is a wake-up call for their administrators and the organizations using the email service. Ten years ago, it was a reasonable decision to stay on-premises. Five years ago, you could argue the same case and companies with bad network connectivity to the internet or specific security requirements were happy to stay on-premises. Now? In a world of increasing threat, staying on-premises looks a lot more risky. For most, it's time to move to the cloud.
At the Ignite 2021 event, Microsoft announced that Teams will have multi-geo capabilities later this year. The same $2/user/month uplift as used for other multi-geo workloads applies to Teams. The announcement is not unexpected. Teams consumes services from Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft 365 Groups, all of which are already multi-geo capable.
Nearly seven years after the introduction of Office 365 Groups, Microsoft has finally admitted that tenants might just have a problem with "group sprawl." In other words, tenants have too many underused or unused groups because the groups have been created without oversight and not managed thereafter. Microsoft wants to discuss the problem with tenant administrators. Practical365.com thinks this is a great idea and strongly supports the initiative to get a handle on group sprawl once and for all.
