If under a VM the code quits cleanly then the problem is either some other
Outlook integration code that's running on the problem machine or hung
instances of Outlook. Make sure task manager doesn't show an Outlook process
running before trying again and see if Outlook quits cleanly. If not it's
probably some other code, which you can find by a process of elimination.

Hi, ken, i tested my addin in VMware, outlook can quit normally. It seems
that the problem is caused by some other things, i remembered that i
killed
the outlook.exe process in task manager manually(Atl + F4) while it
quiting
for several times. Maybe this caused the outlook out of its manner.
