Outlook COM Addins Fail to Load

[StevenBr]

I am developing a COM addin for Outlook in VB 6 and have noticed that it now
fails to load on startup, despite the registry setting being correct for that
behavior. In fact, I unloaded another COM addin (in this case, for
Stamps.Com) which has always worked, and cannot get that to load now either.

The behavior is this: I go into the COM Addins list in Tools/Options, and
the checkboxes for the 2 addins (mine and Stamps.com) exist. I check them,
close the dialog, and reopen it, and they are not checked.

I do not believe there is a problem in my addin code, as it loads and works
as expected when I run it in debug mode in VB 6 along with Outlook.

I have logged registry access, and see that Outlook correctly looks for the
registry information for both addins, and seems to find it. I've logged file
access, and Outlook never appears to try to open either DLL.

Any ideas? Thanks!

If that checkbox fails to stay checked then most likely the addin has been
disabled by Outlook. You don't mention your Outlook version but if it's 2002
or 2003 see if the addin is listed in Help, About Microsoft Outlook,
Disabled Items button. If so highlight it and click Enable. Exit and restart
Outlook.
