Solution 1Recommended

Install the Microsoft 365 Mobile App for Android

Since Office 2021 licenses are strictly for one PC or Mac, you must use the separate Microsoft 365 mobile app to view or edit documents on an Android tablet.

Office Home & Student 2021 is a perpetual (one-time purchase) license limited to exactly one Windows PC or Mac. It does not grant installation rights for Android tablets or iPads.

1
Open Google Play Store

Unlock your Android tablet, open the Google Play Store app, and type 'Microsoft 365' into the search bar.

2
Download the App

Locate the official Microsoft 365 (formerly Office) application and tap 'Install' to download it to your device.

3
Sign In to Your Account

Launch the app and sign in with a free Microsoft account. Note that if your tablet screen is larger than 10.1 inches, a paid Microsoft 365 subscription is required to unlock editing features.

Frequently Asked Questions

Can I transfer my Office Home & Student 2021 license to a new computer?

Yes, Office 2021 can be transferred to another computer, but it can only be active on one PC or Mac at a time. You will need to uninstall it from the original device before activating it on the new one.

Is Microsoft Office free on Android tablets?

You can download the Microsoft 365 mobile app for free. However, if your tablet screen is 10.1 inches or larger, you will be restricted to viewing files unless you purchase a paid Microsoft 365 subscription.

Can multiple users share one Office Home & Student 2021 license?

The license is tied to the single Microsoft account used during the initial activation. Multiple people can use the same computer where it is installed, but they cannot install the software on their own personal devices using that single license.
