All you have to do is add a new mailbox just like any other, but when it asks for an extension, try hitting the * key. If that switches to none or moves on the the next prompt in mailbox programming, just continue on as normal. If it takes you back to Mbox AA Other, just go back in to programming of the mailbox via the change instead of add, in order to finish off programming the mailbox. Make sure the ext is set to none. Remember to initialize that mailbox so it can be used.
