The light version of Outlook Web App includes fewer features. Use it if you're on a slow connection or using a computer with unusually strict browser security settings. We also support the full Outlook Web App experience on some browsers on Windows, Mac, and Linux computers. To check out all the supported browsers and operating systems, click here.


To protect your account from unauthorized access, EMHS automatically closes its connection to your mailbox after a period of inactivity. If your session ends, refresh your browser, and then log on again.
