Whenever I save and close a calendar item I just created, I end up getting
a
pop up box that says Microsoft outlook has encountered a problem and needs
to
close... Send error report. The error signature contains the following
information
AppName: outlook.exe AppVer: 10.0.6626.0 ModName: mso.dll ModVer:
10.0.6804.0 Offset:00002600.

I have sent in the error report. Any help would be greatly appreciated.

Thank you.
