Having an odd appointment issue - it's happened before with other users, so thought it was just a quirk, but has happened two times since, so ...
User sent out a monthly appointment to a group (not recurring, separate appointments). User tries to delete the appointment, but it doesn't prompt to remove from others mailbox.
She found this odd, so she looked at the properties of the appointment, only she can't. There is only the Appointment and Options tab. Looking at other appointments sent out, it looks as if the appointment properties are missing on some (so she can't see who has accepted or declined) and looks as if it is now a personal appointment, even though the recipients of these appointments show it as a group appointment in their calendars....
Thoughts?
