Unassign Client Access Licenses

You have reached the maximum number of CALs that can be assigned to user accounts or devices. To resolve this issue, you must unassign a license to enable the license to be reassigned to another user account or device.

For more information about unassigning a CAL, see "Unassign a Client Access License" at the Microsoft Web site (https://go.microsoft.com/fwlink/?LinkId=136788).
