The following alert appears within a Dynamics 365 mailbox record:
"An error occurred while synchronizing the item [Item Name] from Microsoft Dynamics 365 for the mailbox [Mailbox Name].
Email Server Error Code: Crm.80040216. An unexpected error occurred. "
This message may appear if Server-Side Synchronization attempted to synchronize an item with Microsoft Exchange but encountered an error. This is typically a temporary issue and the item will be retrieved successfully on the next synchronization cycle (typically 15 minutes).
If this message does not persist on the next synchronization cycle (typically 15 minutes), this message can be ignored. If this message persists and mentioned item is not being synchronized by Server-Side Synchronization, you can contact Microsoft Support.
