In order to fix a BB issue for a user, we have exported the mailbox content to a PST file, removed the existing mailbox, recreated a new mailbox, then finally imported the PST file back in. This has resolved the BB issue. However, now we have a new major problem:
For ALL the old meeting entries in his Calendar, if he wants to cancel a particular meeting occurence, it will be deleted without prompting user the option to send cancellation to attendees or not. It works fine for new meeting entries.
As this user is an MD and we've basically tried everything, any tips or advise would be great~
