Hello -
We have about 30 conference rooms that are currently configured as normal user mailboxes in our Exchange environment. These mailboxes were created in Exchange 2000 and have over the years been migrated into Ex 2003, 2007 and finally Exchange 2010 SP2 (no update rollup). Since the old way of processing cancelled meeting requests was to just append the subject with "cancelled:" in the conference room's mailbox, we have a lot of "cancelled:" meetings, especially ones that repeat forever in these rooms, and meetings that were created by ex-employees.
If I switch these normal users to resource mailboxes, what should I expect to happen with the existing appointments in the room? Will the "cancelled:" appointments be deleted?, will the organizers / participants be notified in any way? What's the best way to address this issue and configure our conference room mailboxes the proper way for Exchange 2010?
We're also using the Calendar Repair Assistant and it's set to run nightly during off hours.
Thanks
Nick
