ServerSideSink CRM 2013 failing: Exchange sync worker for the mailbox is failed/terminated RRS feed

  • Question

  • CRM 2013 SP1 UR 4 Onpremises and Exchange 2013 CU10 Onpremises

    Some mailboxes get disabled and can't be enabled again. Outgoing profile and ACTTests all succeed but after enabling they disable immediately.

    The errors:

    Claus, Santa

    The mailbox Claus, Santa v. has been disabled for synchronizing appointments, contacts, and tasks because an error occurred while connecting to the Microsoft Exchange server. The owner of the associated email server profile Customer Exchange has been notified.

    Email Server Error Code: Web.SendFailure

    Exchange sync worker for the mailbox is failed/terminated : {GUID}. Exception details : Unhandled Exception: Microsoft.Exchange.WebServices.Data.ServiceRequestException: The request failed. The underlying connection was closed: The connection was closed unexpectedly.
