Office 365 check if email reached our tenant or rejected
Posted on 2017-10-12
In an Office 365 E3 subscription/tenant, is there a way to check if incoming mail from a specific email address successfully made it to our mail store, was rejected for some reason, or other? Trying to track down why a user is not getting mail from a specific user and the sender is not blacklisted, and email is not in spam/junk folder.
When we used to have an on-prem Exchange server, there was a Message Tracking Center which, while basic, allowed us to identify things like this.
Does Office 365 admin functionality support this ability in another way? PowerShell perhaps if no GUI?
