Incoming Emails Status shows Failure

Posted on by 16
In my D365 Customer Service, I have a user whose emails stopped Outgoing and Incoming, then after I approved the mailbox and ran the test now shows Outgoing Emails status as Success, but Incoming Emails still shows Failure status.
We use Exchange online, and the configurations on the mailbox show the same as other users with Server-Side Synchronization or Email Router option chosen for both Incoming Emails and Outgoing Email fields.
When I checked the alerts it seems to show that there are synchronization issues for unknown reasons.

Any advice to make this account run properly is greatly appreciated.

    Issue resolved itself over time. Was found to be working after second test.
