Com AddIn not staying checked

Posted on 2004-10-27
Last Modified: 2010-05-18
I've got a COM addin that I'm trying to get installed in Outlook 2003 SP1 (recently upgraded, but had the same behavior in a previous version - I thought the upgrade would help).  I'm connecting to Exchange Small Business Server 2003.  The AddIn is listed, but when I check it and close Outlook and re-open, it's unchecked.  I'm logging in as Administrator.  Don't know where else to go.  (As with everything I do, it's urgent.)  

Any assistance would be greatly appreciated (as you can deduce by the point value).

    Does it happen to any user outlook connected to that exchange server ?

    Have you tried to create a new profile in outlook going to control panel > mail > show profiles and use that profile and check if the same behavior occurs .

    Is your exchange server fully updated ?

    Yes, it's for any user connected.  I haven't tried creating a new profile, and yes, there are updates available.  I'll try creating a new profile after installing the updates.

    1.rst : ..looks like an uncomplete shutdown of outlook.
    if outlook doesn't stop completely - a intended restart will be a start of a second instance !

    and add-ins are only loaded once : in the first instance.

    check the taskmanager if outlook is really off.
    if not kill it and restart outlook and have alook where your add-in is.

    2.nd : scenario if outlook encounted errors the LoadBehavior Value in the registry are set back to "2".
    manually reset to "3" means it will come up again....

    2.nd : scenario
    The LoadBehavior Key you can find in

    if its really reset to "2" than there is a problem in the add-in...swallowed/loaded - spit out again
    i had this building my own add-in

    Don't forget to press F5 for View refresh after test-starts...

    This (error in dll) was causing it not to load.  Thanks!  All is now working as expected.
