I'm stuck in some sort of strange loop.
I tried to create an office 365 user, and did not have any available licenses. I followed the link to purchase an additional license, then went back and created my new user.
You guessed it - I now had two, identical mailboxes.
I deleted the Office365 user, and used Powershell to remove the mailboxes.
I then attempted to recreate the user, but it failed again because the email address wasn't considered available.
Using Powershell: When I run get-mailbox, it does not show anything. When I run get-user, it shows name as "User" and name_ also as user.
Using the web interface, there is no user in Office365, but 3 identical users with the same email address in "Deleted Users". I have restored one of these, but there is no corresponding mailbox.
How can I purge everything so I am able to re-create the user, or at least be able to recreate the user?
When I go to the Office365 admin interface, there's a notice that I have an error:
Exchange: The value "<name@domain>" of property "UserPrincipalName" is used by another recipient object "namprd07.prod.outlook.com/Microsoft Exchange Hosted Organizations/<domain>.onmicrosoft.com/<user>_a999aaa999".
