In CRM mailboxes are approved and test&enabled, but getting integration error

Posted on by
In Dynamics 365 I had to update the email address for one user, because they wanted the App for Outlook add-in connected to an email different than the email connected to their user in Dynamics.
After I changed it, I approved and Test& Enabled the mailbox. I got a confirmation that it was successful. I also advised the user to remove the add-in manually from their other outlook. But it is not appearing in the new one, although in the settings it is marked as Added to Outlook.
Additionally, I keep seeing errors on this (and lots more) mailboxes. The error is the following:
Appointments, contacts, and tasks for the mailbox abc couldn't be synchronized. The owner of the associated email server profile xyz has been notified. 
But this is wrong since abc is actually a recipient of the email and not my user, but rather a contact in Dynamics 365. The user is xyz.
So not sure why this error is appearing.

    Check for Duplicate Email Addresses:
    Go to Advanced Find in Dynamics 365.
    Search for any Contacts, Users, or Queues with the same email address.
    Resolve duplicates. Only the user should have the email.
    Disable Server-Side Sync on Contacts (if not needed):
    If you don't sync appointments for contacts, this error can be ignored or suppressed.
    Go to Mailbox > Contact (abc) (if exists), and disable synchronization.
    Re-Approve and Re-Test the Correct Mailbox:
    Go to Settings > Email Configuration > Mailboxes.
    Open the user mailbox (xyz).
    Make sure:
    It's marked as Approved.
    It passed Test & Enable.
    Click "Test & Enable Mailbox" again just in case.
    Check the Email Server Profile:
    Confirm that the email server profile (Exchange Online) is configured correctly.
    Make sure it’s assigned to the right user mailbox, not a contact
