    Problem with Interop on XBAPs?

    I have two apps, one is a standalone WPF app and the other is an XBAP. Both use a common code base (shared project) to access Outlook data using COM Interop.

    The WPF app runs fine and has no problem reading/writing Outlook data. The XBAP, running at the same time, always fails with this error:

    Retrieving the COM class factory for component with CLSID {0006F03A-0000-0000-C000-000000000046} failed due to the following error: 80080005

    So does this mean XBAPs can't use Interop? The XBAP is running as a full-trust application.

    When you run the xbap application, check whether the outlook is running or not. If it is running, close the outlook app. then try running the xbap application.

    And if this doesnt work, then try to run the application with different access rights. i.e from full-trust to partial trust...
