Set Up Apple Calendar for Your Exchange Account

If you are using Apple Mail to access your Office 365 account, you'll probably find that Apple Calendar knows where to find your calendar information. This article describes how to add your calendar to Apple Calendar manually. Caution: If you're interested in using Two-Step Login for Office 365, please note that it doesn't work with Apple's Mail and Calendar on MacOS (it only works with those apps on iOS).

  1. Open Calendar, found on your dock or in your Applications folder.

    NetID@cornell.edu
    substituting your own NetID.
