Cannot connect to exchange with Outlook from remote site

    Question

  • Hi,

    Outlook 2010/Exchange 2010

    I'm having a problem where after a server reboot a couple of days ago I can no longer receive emails from Outlook when outside the LAN. OWA works fine, as does my phone, but not Outlook.

    The proxy settings are correct (worked fine before the reboot) and the PC can evidently find the server as OWA is OK. It just gives the message Trying to connect ...

    All the Exchange services on the server appear to have started OK and I can't find any telling error messages in the Event Viewer.

    Can anyone please advise on where to start looking?

    Thanks

  • You mean via Outlook Anywhere?

    Can you create a new Outlook Profile and try that?

    Ensure all the services are really started with test-servicehealth and also ensure all the App pools are running. IISRESET if necessary.

    Test OA here as well:

  • Hi,

    Can you check the outlook connection by holding CTRL +Right Click Outlook Ion on Taskbar and verify the Connection Status?

    Is this affected for all the users?

    Can you check the RPCoverHttp(Outlook anywhere) is enabled for the affected user by following Command.

    Get-CASMailbox -Identity "UserName" | FL MAPIBlock*

    MAPIBlockRpcOverhttp should be false

    Are you using HLB? If so check the RPC/Http Persistent .

  • Thanks for your help Andy,

    I though it was called Outlook Web App these days?

    I tried a new profile and same result. It's not just isolated to a single client - it's the same for all of them.

    Test-ServiceHealth returns that all is running and the Exchange App Pools are all started.

    I also tried your link. I only really tested EWS, but are there other ones I should run for an Outlook 2010/Exchange 2010 environment?

    Thanks, Neil

  • Hi Harishpriyan,

    Not sure on the ctrl+right click on the taskbar icon - it doesn't seem to give a connection status. The status when I run Outlook is "Trying to connect".

    Yes, it's all users. The Get-CASMailbox command shows MAPIBlockOutlookRpcHttp as false.

    We're not using HLB (assuming hardware load balancer?)

    Any more suggestions most welcome.

    Thanks, Neil

    Test Outlook Anywhere with that link.

  • So what were the results when you ran the rests from http://testexchangeconnectivity.com?

    Yes, you should be exercising the tests in the "Microsoft Office Outlook Connectivity Tests" section.
