Are you using Form Regions? I have seen this issue reported by two other
both using Form Regions.

All,

I have posted here before and received great advice. However, I am writing
a
VSTO Outlook Add-In, and still have an issue where the Add-In loads twice
When debugging and sometimes starting Outlook 2007.

I have tried Mutex, registry checking and a variety of other methods to no
avail.

Any suggestions? My goal is to ensure only one copy of my Add-In loads
and
executes. I have confired the Add-In is loading twice as
"ThisAddIn_Startup"
is fired two times.

Thank you.
