I defaulted and reconfigured a NAM 3.0 on a MICS 6. After I built the mailboxes I went through the initial setup on a few mailboxes I discovered I could not log in to any of them unless I was at the extension itself. If I tried I'd get "invalid password." I don;t do a lot of these but I don;t seem tor recall a setting which allowed for remote mailbox logins.
