Communicator 2007 and Outlook 2007 integration error

/

Error seen in Communicator 2007 R2:

There was a problem connecting to Microsoft office outlook. Your profile is not configured correctly. contact your system administrator with this information.

It can be solved in several ways:

  1. Make sure the default Outlook profile matches the “profile” = e-mail used for signing into OCS, equal your sip address:
    Go to: HKEY_CURRENT_USERSoftwareMicrosoftWindows NTCurrentVersionWindows Messaging SubsystemProfiles
    Change DefaulProfile to your default profile name (Control Panel > Mail > Profiles)

    Or go to: Control Panel > Mail > Profiles, select “prompt for a profile to be used”, restart outlook, select the profile, and click options, and select default profile. Restart outlook.

Another solution can be to run fixmapi.exe on the computer having this problem, If the default profile is already set correctly.

This solved the problem for me on a client running Vista and Outlook 2007 and no Exchange Admin tools.
