"Crm.80040216. An unexpected error occurred"

Posted on by 8
Hi All
I have a large corporate with Server Side sync between their multiple mailboxes and CE. All Mailboxes no longer sync and we are being given /Crm.80040216. An unexpected error occurred/ error appears in Microsoft Dynamics 365 mailbox when opening the failure log.
The listed failure emails/boxes state ObjectNotFound as the failure reason. I cannot find literature around this anywhere.
Can anyone help?

    Based on this documentation:
    This is a temporary issue, but if it is not resolved automatically for a long time, you need to contact Microsoft support team.
