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?

Hi，

Based on this documentation:

https://learn.microsoft.com/en-us/troubleshoot/dynamics-365/sales/an-error-occurred-while-synchronizing-item

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