I've had a few people ask if it is possible to check your LSUHSC email without using VPN. The answer is yes, but you just have to tweak a few settings:

Within Outlook...
1) Open Tools> Account Settings
2) Click Exchange Account and press Change
3) Press More Settings > Connection
4) Enable Connect to exchange via HTTP then press Exchange Proxy Settings
5) Input this for the connection URL: sh-mail.lsuhsc.edu

Enjoy,
