Usually if an addin is disabled that way it means you have unhandled
exceptions, a cardinal sin for addins. Or that you aren't using a shim to
get your own AppDomain for the addin and some other code in that same
AppDomain is crashing Outlook or has unhandled exceptions.

If it remains in Outbox are you messing with the items after they're sent,
or accessing them in Outbox, or not releasing the object references?

The add-in was in the Disabled Items list. After enable it, the add-in was
loaded and the menu appeared. But now email won't go out. They stay in
Outbox forever.

I remember someone had the same email problem and asked for help a while
ago but I could not retrive the mail.It was gone.
