I am trying to configure one of the tabs in AD users and computers (related to modular messaging) but in any event it says that the info I want to assign is already being used by another user (X). However X is no longer employed and his user account and email has been deleted a long time ago - in fact until today X's information regarding his phone extension has been working in the current user's account. I go into ldap and adsiedit and can not locate anything on the former employee X - there is nothing in the lost and found container in AD users and computers either. Any thoughts on how to find this missing information and modify it? Thanks in advance.
