Unfortunately, we never seem to be able to find the scenario that causes this. The issue is that when this happens, COM is not instantiating our addin correctly. The Assertion is there to let us know this fact. When we submit mail, we access our addin -- the reason the message gets sent anyway is that we send through the MAPI spooler if our send fails.
I could yank the ASSERT, but it indicates that a serious problem exists. In this situation, a lot of other things may not work correctly.
There is probably something messed up in the registry when this happens -- I will continue to try to get to the bottom of this. |
