  1. Hi,
    I know this is a bit old however, is it necessary to put in a password? I thought Room Mailboxes are basically disabled user accounts.


    • that is correct yes and when you create them via the Gui the password option is greyed out. In the script you can leave the password section blank as its not needed.
