Exchange 2010 Outlook Anywhere

    Question

  • Hi

    I have a single Exchange 2010 server configure in the same organisation as two Exchange 2003 servers.  The Exchange 2010 server is working fine in terms of mail flow and OWA.  However I can't get Outlook anywhere to connect from remote Outlook Clients.

     

    Running the remote annalyser I get the following results, any help would be great, I'm lost as what to do next.

    Regards

  • Hello,

    Please see below a list of articles that might point you in the right direction. I myself I would start by disabling IPv6 if that one is still enabled on the server. Then I would do a netstat -ano on the Exchange server to see what ports are open and who's litening on them .

  • Hi,

     

    Please try to use Exchange Remote Connectivity Analyzer Tool from outside the network to check the issue.

    Besides I’d like to collect some information with you:

     

    1.    Please run Get-OutlookAnywhere |fl and then post here.

    2.    Please run Get-outlookprovider expr |fl and then post here.

    3.    Please try to run https://domian.com/rpc/rpcproxy.dll and then post the result here.

    4.    Please check settings on RPC virtual directory, if any redirection has been set there.

     

    Regards,

  • Hi

    I actually managed to fix it myself, your point 4 is where the problem was, I had the RPC directories pointing at OWA for some reason.

    Many thanks for your help, if I hadn't of already sorted it, your reply would have.

    Many thanks

  • I am having the same issue. When I ran the MS connectivity analyzer, this is what I got:

    accept/require client certificates isn't configured.
    Client certificate authentication wasn't detected 
    ------------------------
    My configurations -
    The cas server authentication method: NTLM
    ISA server authentication method: basic

    Outlook Client authentication method: Basic

    Not sure what I did wrong but the Outlook client can't find the server

    Any help would be greatly appreciated.
