Today I was approached with a request to change a CRM user’s username after changing the login in Active Directory. Seems like this would be a simple task to do through CRM, however when I tried it and pressed Save, I received this error:
 
“You are attempting to create a user with a domain logon that is already used by another user. Select another domain logon and try again.”
What I tried was first assigning the CRM user record an AD logon who is not already a user in CRM, saving, and then reassigning the user record with the new and correct AD logon. I tried it with a dummy AD user and found success, who would have guessed?

Thanks for the tip. I ran into this issue when I changed a lastname and username for user and forgot to immediatly change her CRM account. It worked perfectly.
