  • Autodiscover for Exchange 2010 issue

    Hi everyone,

    I'm working on an Exchange 2010 Autodiscover issue. Basically, Outlook Autodiscover is not working correctly. I've used the Microsoft Remote Connectivity Analyzer and chose 'Outlook Autodiscover' and all the tests pass with no issues. When I try to create a mail profile, I get this message:

    The action cannot be completed. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action.

    Outlook actually shows info in the fields:
    Microsoft Exchange server:
    Mailbox =SMTP:[email protected]

    So, Outlook gets hung at this step:
    'Log on to server'

    I'm not sure how to proceed if Remote Connectivity Analyzer test passes.
    The server is SBS 2011.

    Active directory domain: yourdomain.local (This is recommended)
    E-mail domain:

    Is your e-mail addresses in the format of [email protected]?

    With auto discovery you enter your e-mail address and password and Outlook should then pop up and ask for your username which should be in the following format:
    AD_Domain\username or (where you leave the .local part out)
    [email protected]_Domain

    yourdomain\username or
    [email protected]

    If your e-mail addresses (the part before the @ sign) matches your usernames then you can add a UPN suffix so that logon names and e-mail addresses are the same. (I.e. add a UPN suffix for

    Hope this helps.
