Communicator could not retrieve calendar or Out of Office information in coexisting environment RRS feed

  • Question

  • We are running xchange 2007 SP1 on a Windows 2008 Server.  We are in the process of changing, but we still have the Exchange 2003 system. 
    Outlook 2007 seems to be running OK. We added a unified messaging server, also running just the UM service to our domain.  We are running Communicator 2007 R2.  In Office communicator we get the messae the it "could not retrieve calendar or out office..."
    I have ran the communication test in outlook, copy below.  I only see one issue that the UM server is on two locations>
    UMSRV1 - unfied messaging Server running Exchange 2007 UM role only.
    Exchsrv2 - Exchange 2007 Server running CA. HUB, UM messaging roles.  UM role is disabled.
    OCSSRV1 - is the communications server.

    I have looked at DNS, and autodiscover, but I am not sure what i need where.  Any help is appreciated.

  • Well, IIRC (and I might not as I've yet to read up on what's new in R2) it's Communicator that talks to Outlook in order to get this info and not the OCS server to the Exchange server so I'm not sure it's a server related problem.

    Just to clarify a couple of things anyhow:

    Are your clients (Outlook 2007?) connected to the Exchange 2003 server or to the Exchange 2007 server?

    Are all clients and servers in the same domain or are just the new servers in the same domain?

    If you enable logging in Communicator, do you see any errors there? What does the event log on the client computer say?

  • All clients are on Outlook 2007.  100 of my 300 users have had their mailboxes moved to the 2007 Server.  the rest are on the 2003 server.
    All clients and servers are in the same domain. 
    there are no erros in the logs and when you enable logging on the client side, all appears fine.
    I thought the Communinator server worked with the UM server to get information from the Eschange server.
    I am thinking the problem lies with the Unified Messaging server not getting all information from the Exhange server.
    Thanks for the replay and any help is appreciated.
