Symptoms

One of the following alerts is logged in the Alerts section of 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.

  • An error occurred in receiving email for the mailbox <Mailbox Name> while connecting to the email server. The owner of the associated email server profile <Profile Name> has been notified. The system will try to receive email again later.

    Email Server Error Code: Http server returned ServiceUnavailable exception

  • An internal Microsoft Dynamics 365 error occurred while receiving email through the mailbox <Mailbox Name>. The owner of the associated email server profile <Profile Name> has been notified. The system will try to receive email again later.

    Email Server Error Code: IncomingMailboxInternalCrmError

  • An unexpected error occurred while receiving email. Mailbox <Mailbox Name> didn't synchronize. The owner of the associated email server profile <Profile Name> has been notified.

    Email Server Error Code: ErrorInternalServerTransientError

Cause

The error messages might occur when server-side synchronization tries to synchronize an item with Microsoft Exchange but encounters issues such as internal errors or a 503 (Service Unavailable) error. Typically, these are temporary problems, and synchronization usually succeeds in the next cycle (approximately every 15 minutes).

Resolution

  • If the issue doesn't persist during the next synchronization cycle (typically in 15 minutes), you can ignore it.
  • If the issue persists and the mentioned item isn't being synchronized by server-side synchronization, you can contact Microsoft Support through the Help + Support experience in the Power Platform admin center.
  • Additionally, there might be an issue with your email server, so you can first verify that you can send and receive emails successfully with your email service.
