When you try to edit previous calendar entries you get the following error message:
This meeting was copied to your calendar and will not receive updates. Contact your Organizer, <user>, and user us set to be the organiser.
Recreating the calendar items is not an option.
1. A full backup of the Calendar was made before we had this issue.
2. When then re-imported this Calendar.pst to replace duplicates and try to resolve this.
3. We reloaded the Mail Profile.
4. Re-imported his calendar using CSV format, yet the problem still persists.
Any ideas on how to fix this urgently as the user is the Operational Director?
The user also have a Blackberry and I-Pad syncing to Exchange 2010 and a PA handling all the appointments in his Calendar..
