PLEASE allow Super Admins to save their Exchange server URL at a global level where it is not visible to users for security reasons...so the user is not required to enter it if connecting/reconnecting their personal email account via Exchange. If they attempt to connect/reconnect and the Exchange server URL is missing at the admin level, they could click a link to request the admin configure the Exchange settings...much like a user can request additional Sales Enterprise seats and admins are notified by email.
