Hello all,I'm in need of some good advice before I go insane.A user has come to me with a problem, he sends out meeting requests to 8 users, all of which are legit employees with functional accounts etc. However, every time he sends the invite, he gets sent an automated message to say a certain employee can't be contacted as the user doesn't exist (employee left, account deleted). I've checked his account myself, he's definitely not adding this user to the list of recipients. This only occurs when sending out an invite for 2 specific rooms. The rooms are set up as an account on AD. I've checked every setting I can think of and just can't put my finger on it. If its any help, the ex-employee in question was a P.A., and used to be an organizer for past meetings. Any help greatly appreciated!
