tl;dr: Ensure the accepted domain(s) in Exchange Online are configured as Authoritative, not Internal Relay, even if you're in hybrid, to take advantage of Directory Based Edge Blocking. Those of you who have worked with Exchange Server for a long time and those familiar with cross forest migrations will probably know about Authoritative vs. Internal Relay domains. When a domain is set to Authoritative, email is delivered only to valid recipients in the Exchange organization. With Internal Rela...

Exchange message transport & routing has at times been a bit challenging to understand. Whether it was the X400 based Mail Transport Agent (MTA), Open Shortest Path First (OSPF) based routing in Exchange 2000+, or the effect of Database Availability Groups (DAGs) on mail delivery and resilience. Of course if your mailboxes are completely hosted in Office 365, then this is no longer your problem to worry about.  But for many of our customers, Hybrid or some form of coexistence is still a...

From time to time, Microsoft refreshes the certificate used by the Microsoft Federation Gateway service in Office 365. They just did this again on July 5, 2019. The MFG is the trust broker used by hybrid organizations and by other on-premises orgs that share free/busy information between them. Most Exchange configurations will update the federation trust metadata automatically, but if your on-premises org is running Exchange 2010 or Exchange 2013 on Windows Server 2008 you will need to update...

We’re delighted to announce that Microsoft Hybrid Agent has reached General Availability! We first talked about this agent nearly two years ago at Ignite and we’re very happy to have reached this important milestone today.   The Agent has been available in Preview for quite some time as you probably know, and in that time over 250,000 mailbox moves have been initiated through the Agent. That’s amazing to us, given we often hear customers are hesitant to use Preview code in production....

We are happy to announce our work to allow you to disable legacy authentication is available to you with the second cumulative update (CU2) for Exchange 2019. This provides an important step down the path of removing legacy authentication mechanisms from Exchange Hybrid deployments. This feature is very similar to the functionality offered in Office 365 for Disabling Basic authentication. Why is this feature important? As you probably know, legacy authentication methods are less secure, are vuln...

When an Exchange Administrator creates additional Virtual Directories for Outlook on the Web or Exchange Control Panel, we have found that a few Managed Availability probes fail on Exchange Server 2013 or above.  This occurs because the monitoring probes use the Server's FQDN to access the RPC or MAPI/HTTP frontend virtual directory (e.g. https://ex01.contoso.local/rpc/..., https://ex01.contoso.local/mapi/...).  Unfortunately when the probes resolve the local machine's FQDN, there is a...
