Error:
Cannot drop the user ‘dbo’. (Microsoft SQL Server, Error: 15150)
Problem: trying to unmapped a user to a database , you may receive the above error message. This is because the dbo user is assigned the login of the user you are trying to remove. You will need to run the following query to change the user
exec sp_changedbowner ‘new user’
or if this is part of Active directory
exec sp_changedbowner ‘domain\user’
