I am using Azure AD Federation for logins on my Portal. One of my users filled out their profile incorrectly, so I wanted to remove their contact record so that they could "re-register" their user account in the portal. Apparently I only completed the job half-way, because now when they try to register they get a message that "The user name UID is already taken". I looked in all the obvious places for a record containing that UID, but could not find anything. Can anyone point me to where I should be looking to clean out that record?
Thanks
