Hello, I have taken over the duty of maintaining the phone system at my company, and am having an issue. We use T7316E. Someone's mailbox became locked, so i reset the password, and its still locked. I then deleted his mailbox, and tried to re-add the mailbox, but I am getting (ext Assigned) when I put in his extension. I am pretty sure all the mailboxes are assigned the same extension as the call in extension here. Is there somewhere else I need to delete the mailbox also? Thanks.
