I have a user who is having a weird issue in Outlook 2010. We are using it in conjunction with Exchange 2003.
What happens basically is that if he has a meeting in his calendar, recurring or not, and that meeting is updated by the organizer, he gets a message notifying him of the update. If he deletes that message, the meeting disappears.
Oddly enough, inside the message at the top it says "Please respond" but at the same time the buttons at the top of the message only say "No response necessary".
If he goes into his calendar and right-clicks the meeting (which at this point is semi-transparent and "tentative"), he can Accept it and it will be confirmed in the new time slot.
Anyone have any idea why this is happening? Thanks!
