One of the prevalent requests we receive is to remove recurring meetings / appointments from room mailboxes which were created by user's who no longer exist within the organization. The problem we're having: when a user is terminated, within a week, their mailbox data is exported and then the mailbox is removed from the database. As it always seems to go, we receive the requests only after the mailbox no longer exists. To that end, I have two questions:
1) After the user is terminated and the mailbox is removed from the database, are there any feasible options to remove the orphaned calendar items? If so, how can this be accomplished? I am unable to find a supported solution.
2) If the first question isn't an option, I'll need to put onus on the manager to whom the user reported; to provide us with specific meetings / appointments that need to removed. Without re-enabling the mailbox, is there a feasible option to remove specific calendar items from the terminated users' calendar? If so, how can this be accomplished?
Any assistance would be very helpful as I've been unable to locate any supported / unsupported options.
