2011 Outlook client authentication issue RRS feed

  • Question

  • Hi,

    We've got a brand new install of 2011 which we want to use in IFD mode. It's working fine from the web using its URL. It prompts for username/password which is correct.

    However, we have an issue when trying to connect to it via the outlook client. It says "There is a problem communicating with the Microsoft Dynamics CRM server"

    I checked the event logs on the CRM server and can see the issue below, it seems it is trying to use integrated (on-premise) authentication which won't work. I need to specify a username/password somehow but the connection dialog in outlook doesn't seem to allow this.


    An account failed to log on.

        Security ID:        NULL SID
        Account Name:        -
        Account Domain:        -
        Logon ID:        0x0

    Logon Type:            3

    Account For Which Logon Failed:
        Security ID:        NULL SID
        Account Name:        Mark
        Account Domain:        LAPTOP2

    Failure Information:
        Failure Reason:        Unknown user name or bad password.
        Status:            0xc000006d
        Sub Status:        0xc0000064

    Process Information:
        Caller Process ID:    0x0
        Caller Process Name:    -

  • Can anyone help on this?

    The account name/account domain shown above are local to the machine. I need to specify the domain/username/password somehow for outlook to connect with.

  • Hi,

    Finally the issue got resolved.

    There were duplicate SPN records in ActiveDirectory causing this problem.

    I have deleted all the duplicate and unnecessary SPN records, now i can able to configure Outlook client using IFD url with no issues.

    Do you have any other ideas?  This is the exact problem we are having also.
