Period char in mailbox name


Anyone found a way of getting period chars in mailbox names?

The only way I know of setting the mailbox name is to make it a user mailbox, and that disallowes periods:

username must only contain letters, numbers, and/or underscores (_)

I’m trying to transfer to DH a domain and retain the mailbox names, some of which include period (email addresses need to be retained and I don’t want to inflict different email user-part and mailbox names on the users).



I’d contact support directly and see if they can figure out a solution for you.
