Change in Public Calendar behavior
 

I am using OLK 2003 SP1 on Exchange 2003 SP1.

I am the creator and owner of a public folder/calendar where I track
Training classes. Previously, when I would add a class, invite staff and
invite myself, I would be prompted with "Do you want to update your calendar
now?" and say yes. Now, I don't get the message. Instead, I ALSO get an
emailed invitation.
This is very annoying. Now only one event has happened - my machine was
reimaged. My admins claim nothing was changed, but I disagree.

Can anyone shed some light on what hotfixes or other setting changes may
have caused this change in behavior? I'd really like it back the way it was!

Thank you,
-Monica
