You can access Olivet email directly by visiting email.olivet.edu and entering your full Olivet email address (<username>@olivet.edu) and your email password. If you are a new student and have not yet changed your email password, you will use the default password (see above).
You can also access your Olivet email account by logging into My Olivet. At the middle-center of home page you should see a button labeled "email.olivet.edu." Just click that button to be taken to the email login page.
