A user has left the company - should I delete them?

Yes, you should only keep current users on the system. If the user is an administrator, you will need to complete the Delete Administrator form to remove them from the service. 

If the user was not an administrator, they should be deleted by an administrator. Further details on how to do this can be found in the Administrator User Guide.

If you are a Trust, please refer to the Digital Helpdesk for guidance.
