YESYESYES!!!!!

Now it works. If I Invoke() the call manually it works. But now I found
a different problem.

Once I Save an unsaved mail, the "pMailItem" seems to become bad. I
can't pMailItem-Release it. Or Invoke Save again. Both causes a crash.

Does the Save invalidate the pMailItem? Don't I have to release it? Or
do I have to wait for the Save to finish? Somehow...
