Can't leave voicemail for users on some servers but not others RRS feed

  • Question

  • We have 3 Exchange 2010 servers and 3 Exchange 2013 servers (we are in the process of moving everyone over to Exchange 2013.)  

    When we enable UM on a mailbox that is on one of the Exchange 2013 servers, everything works.  However when we enable UM on a mailbox on the other 2 servers, we receive the message "sorry, you have a mailbox that is not supported by this unified messaging server."

    We've re-checked the dial plans, gateways, etc. and are completely stumped.  Any assistance or pointers would be greatly appreciated.

  • Can you describe your architecture in detail?

    Are the 2010 Mailboxes UM enabled?  What are you using for the "phone system"? Lync? Something else?

    Are you moving over Um enabled mailboxes or only UM enabling once move to 2013?

  • Enable UM from Exchange server versions that are hosting that mailbox.  In other words, try to avoid enabling 2010 mailboxes for UM from a 2013 Exchange server, and vice-versa.
