Here is my delima, we are running CUCM-BE 7.0 with LDAP integrated. I have two users that both have mailboxes. However, user A (ext. 7980) was moved to a position where she will not have a phone but will still be using a computer and therefor need an AD account. User B who had ext. 2866 is going to be moving to take over user A's old job. She will inherit extention 7980 and 2866 will not be used for the time being. I went ahead and in CM associated user B with the device and set her primary extention as 7980. I removed device association with user A and have none as her pri extention. On the CM side all is well, however on Unity it will not sync. I am sure this is because user A still exists and because they dont have a primary extention it basically says no. All I really want to do is just remove the mailbox from user A (however cant do this because it is synced with CM which in turn is synced with AD) and then sync user B and it should inherit the new extention (I think). Does anyone know how I can execute this correctly.
