When I receive an invitation via email in Outlook 2007 (2003 did the same thing), it automatically posts the item to my calendar as “tentative” upon receiving it. It does not actually accept the invitation (auto-accept is not turned on) but still the item stays on the calendar until I accept, or decline it. If I delete an invitation without responding to it at all, the item stays on the calendar until I delete it from my Deleted folder.
This never bothered me before but now it’s causing problems when I sync to my Google calendar (for reasons I won’t get into here).
I have not found an option to turn this off. Is there any way to suppress this?
