To forward your UL-Student Email to another address you:
Login to your ul account on a campus computer (csis does not count)
Open Outlook (generally there's a shortcut on the taskbar)
In the left-hand menu there should be a rules option (it may be a suboption, will double check and update this).
Select the "New Rule" option near the top of the window.
In the new pop-up window select forward mail, and input the desired e-mail address you want it forwarded to, leaving everything else blank.
Click accept and from now on all e-mail sent to your address will be forwarded
Side Note: It may be a good idea to select the "Delete e-mail after forwarded option" because the memory for student e-mail allocation is quite small, probably much less than whatever you're forwarding it to.
