I have an issue where whenever I create an appointment in Outlook 2007, save
it, then go back into it and modify it in any fashion (change location, add
an attendee, etc) it automatically changes the appointment to recurring
weekly without an end date. SOMETIMES, I can simply go back into the
appointment and remove the recurrence and that fixes it... other times I have
to delete the appointment completely and recreate it as I wanted it to be.

A work around I found is that I can change it to end after a single
occurrence... but that's just not reasonable.

Anyone know what could be causing this issue? What might be forcing the
appointments to recur upon editing? Any help would be greatly appreciated -
I'm pulling my hair out here.
