Hybrid Server-Side Sync - Receiving 'InvalidSystemUsersOnEmail' for one user.

Hello,

I have one user in my system, newly setup, that is unable to send emails from CRM. I have the org setup with Server-Side Sync for Incoming/Outgoing/ACT and when doing the Test/Enable, everything passed with "Success" messages. Our setup for Server-Side Sync is hybrid with Exchange on-prem and CRM 2016 Update 1 online. Has anyone else run into this error? Can you let me know what it means and what I might be able to do to resolve the issue?

Note: I've already tried disabling the mailbox, doing the approve email, and then testing/enabling the mailbox again. Everything passed when I did this again but once again, no Outgoing emails will work through this mailbox.

Thanks!

This issue resolved itself after the user logged into CRM for the first time. It seems that these emails won't send from the user's account unless the user has logged into CRM at least once.
