Outlook on the web (for email, calendar, contacts, and tasks) requires no configuration and is available anywhere you have an Internet connection. For example, if you are away from the office (don’t have your own computer with you), and you need to check your UW-Madison email and calendar on someone else's machine, log into the web address: https://email.wisc.edu/
Note: You may also click on the Email/Calendar link found on many UW-Madison websites such as www.wisc.edu (the UW-Madison home page).
