But since the mailbox has been migrated, users no longer receive such notification. Please advise what can be done to correct this behavior. Thank you. Never stop learning

Hi, How about creating a new test resource room and check if the issue also happens on the new room? Collect the room information by running the following command: get-mailboxcalendarsettings –ID room |FL Thanks, Simon
