HI All, i setup my Office 365 with this account:
This was the main admin account and a mailbox was setup for it etc...
I noticed that emails were bouncing back when sending to this address, decided to create a new admin account and deleted this one, i was going to recreate it.
The user account is gone but it shows "firstname.lastname@example.org" twice under the exchange mailboxes, i cannot edit the email address and therefore cannot create a new user as it says this email address already exists.
Been on a few sites and tried to remove it via Powershell but without any luck.
I am desperate to get this mailbox removed as i need to recreate this user account as i'm not getting any emails through
