Insufficient privileges error when changing Account ownership of a Portal enabled account
|Knowledge Article Number||000003835|
Account Owner is unable to transfer an Account that has Customer Portal enabled to another user, however a System Administrator can.
This is expected behavior: When a customer portal account is being transferred, the role of any portal users is also changed. You cannot change a user's role without the manage users profile permission. So in order to transfer ownership of this account the user would need to have the manage users profile permission.
Edit Self-Service Users Permission will also work for transferring records
