Unable to sync Sharepoint 2013 tasks with Outlook 2013. The Autodiscover service couldn't be located. RRS feed

  • Question

  • Hello all!

    I stuck with syncing tasks between Sharepoint 2013 and Outlook 2013. Test user for whom I turn on task sync has mailbox on Exchange 2013. Exchange 2013 works in co-existance with Exchange 2010. More info in this topic.

    I got error: We weren't able to sync your tasks. This could be because your mailbox is on an
    Exchange server that isn't supported for syncing tasks. Please contact your administrator for more help.

    Sharepoint ULS log shows next:

    • AutodiscoverLocalException: The Autodiscover service couldn't be located

    • Exchange sync - Autodiscover Failed for user 18920d86-8697-4bdd-aaca-4f39c4b898d1. Error UnknownError

    As I understand, X-FEServer indicates on which CAS the probe was run. X-CalculatedBETarget indicates the Mailbox server to which the request is routed. In the log SVC-E13CA-01 is Exchange 2013 CAS and ca-hub.mydomain.local is the Exchange 2010 CAS.

    I think that request from sharepoint is routed to wrong cas server. It should go to the SVC-E13CA-01 Echange 2013 server, but it goes to ca-hub.mydomain.local which is Exchange 2010. Am I right? Or my interpretation of the error is wrong. Also I don't how to resolve this. Can anyone help?
