Office 365 (iOS 7) - Subscribe to an external calendar

Best Effort Support Only

This document contains instructions on using a non-Microsoft email client, such as Apple Mail or Thunderbird. Microsoft does not recommend these clients for use with Office 365, and there are often significant limitations in client functionality as a result.

Because of this, the DoIT Help Desk is only able to offer best effort support for these clients, and certain issues may require the use of a Microsoft client in order to be resolved. For more information on Office 365 client support, please see: Office 365 - Which clients/protocols will be supported?.

The following document explains how to subscribe to an external calendar using the iOS Calendar app (iPhone, iPad, or iPod Touch).

    • Tap on Done at the top-right of the Calendars display to return to the main iPhone Calendar display and confirm that you see data on a day that is appropriate for the calendar to which you have subscribed.
