Public IM connectivity issue RRS feed

  • Question

  • For public im connect we can see contacts in communicator from aol, msn and yahoo when attempting to message them communicator clocks for a second or two then returns an error

    "This message was not delivered to xyz@aol.com because the service is not available:"

     

    Originally our OCS edge server would have application errors similar to the following, these errors stopped about a week ago.

     

    Event Type: Error

    I run the error through OCS error and it displays

    C:\Program Files\Microsoft Office Communications Server 2007\ResKit>lcserror C3E
    93D6D
    0xC3E93D6D -> (SIPPROXY_E_CONNECTION_EXTERNAL_INTERNET_ACCESS_DISABLED)  (C:\Pro
    gram Files\Microsoft Office Communications Server 2007\ResKit\RTCERes.dll)
    Remote user client cannot connect because access is disabled.
                   

    I don't see exactly where I may enabled access for this "remote client" though I think this has to do with remote OCS users and not public im. Remote OCS seems to be working.

     

    The LCS best practices analyzer doesn't report any great information and the validation fails with a few errors but mostly login related which still happens on the internal ocs server but login works fine.

     

    On the status page of the OCS 2007 server in computer managment it shows under

    External user access

    Remote user access has a green check

    anonymou suser access has a green check

    federated contact has a red x

     

    Everything under federation and public im has a green check though there are no allowed nor blocked federation partners.

     

    What should I check to further troubleshoot this issue, any suggestions or solutions are appreciated.

    Thanks.
