Well, I would say that your are correct on the default security code being reset. I just tried changing my own and our default that was set last year does not work... Now when I try to check my VM, I am met with "That security code is invalid" and then "maximum tries exceeded, goodbye".

I found the post below from 2010 where this guy had what seems to be a similar issue. You mention there being a mailbox called "default" as you did above. Is there a way to identify this mailbox from the emanager software or would I need to be consoled in and use some other Toshiba software or Putty?
