I'm running SBS 2011. I have a user that I'm being asked to change their user ID. We use "cryptic" user ID's that represent their job duties, so if a user is the director of the maintenance, their user ID might be dom01. If that user leaves and is replaced, the new user would be given the user ID dom02. In this case they want the user ID to more closely match the position that the user does. So the user might be xyz01, and my upline wants to change it to abc01. The user's job is not changing and they still need access to all the same mapped drives, shortcuts, and email. This change also includes being able to get email as the new user ID. I'm wondering what you would recommend, renaming the user or copying the user and starting "fresh"?
