I've got a COM addin that adds a toolbar to Outlook inspectors.

In another process I call the Simple MAPI MAPISendMail function. When the
new e-mail dialog pops up, my addin toolbar does not appear. I figured out
that the same behavior happens if I open up a new send e-mail dialog via the
send to mail shell context menu.

I heard a long time ago that in some cases Outlook opens in a mode where no
addins are loaded. However, even if Outlook is already running (in which
case my addin is already loaded), my addin toolbar does not appear. I ran
through it with a debugger, and none of my code is hit for this particular
inspector.

What if I use Extended MAPI to do this? Since it happens for both Simple
MAPI and the shell send to mail context menu, I'm assuming that it won't work
for Extended MAPI either. Is there something else I can do about this or is
it just a limitation of Outlook?

Thanks
