How to install Office Insider apps on iOS

Office Insider for iOS is available in one level, called Beta in Apple TestFlight.

Note: If you already have an App Store version of the app installed on your device, the Beta app will replace that version. Once you’ve downloaded the Beta app, you’ll see an orange dot next to its name that identifies it as a Beta build.

Install Office Insider apps

  1. Using your iOS device, click the following links to open each app invitation:

  2. If you don’t already have Apple TestFlight, you’ll be prompted to install it.

    • Install TestFlight from the Apple Store.
    • Review the Terms and Conditions and information that’s collected when you use your apps.
    • Select Accept to install TestFlight.
  3. For each app in step 1, click Join the Beta > Start testing > Accept > Install


  • Each build is available to test for up to 90 days. You can see how many days are left under the app name in TestFlight. TestFlight will notify you when a new build is available.
  • There are a limited number of seats available in the iOS TestFlight program. We periodically remove inactive users (those who have not updated their build) to make space available. If you are unable to join, please check back in future months.
