I'm working on resolving an issue for a user that needs to reschedule appointments in 3 Conference Rooms when needed.
The user will open the meeting request and hit 'decline' and then attempt to edit the response before sending it back but then the appointment closes and the following message appears:
"You cannot respond to a meeting without an organizer. You must add an organizer field to the item. "
-End User has Full Mailbox Access
-Listed as a 'Owner' of the Calendar
-Delegate Rights granted to the Calendar as well
-Not in Cached Mode
Check Office updates and Office is up to date on patches.
User does not have a blackberry device.
Not sure of what else to do...I have researched this topic and all the items I have tried have not worked.
