You must use an account that is in the Domain Admins group to perform this procedure.

Click Start, click All Programs, click Windows Essential Business Server, and then click Windows Essential Business Server Administration Console.
Click the Users and Groups tab, and then click User Management.
Click the name of the account that you want to remove.
In the tasks pane, click Remove user account.
If the user's Documents folder is not redirected to a shared folder, in the Remove User Account dialog box, click Yes.
If the user's Documents folder is redirected to a shared folder, click Delete the user's Documents folder to delete the folder from the server, and then in the Remove User Account dialog box, click Yes.
Removing a user account releases the CAL if one is assigned to the account. You can then reassign the CAL.
