Verify OS Version and Microsoft 365 System Requirements

Check your current Android version and update your device to ensure compatibility with the latest Microsoft 365 mobile apps.

Microsoft typically limits support for Microsoft 365 mobile apps to the last four major Android versions. As new Android versions are released, older operating systems like Android 8 or 9 are phased out. While existing installed versions may continue to open files locally, Microsoft does not guarantee indefinite cloud service synchronization.

Check Your Android Version

Open the Settings app on your Android device. Scroll down and tap on 'About phone' or 'About tablet', then select 'Software information' to view your Android version.

2
Check for System Updates

Return to the main Settings menu, select 'Software update' or 'System updates', and tap 'Download and install' to see if your device can be upgraded to a supported Android version.

Review Google Play Store Requirements

Open the Google Play Store, search for 'Microsoft 365', and check the 'About this app' section. The required OS section will explicitly state the minimum Android version needed for the newest update.

Frequently Asked Questions

How long will an older Microsoft 365 APK continue to work on Android 8?

While older installed APK versions may continue to function locally for offline document viewing, Microsoft does not provide a guaranteed timeline for how long cloud services, OneDrive synchronization, and account sign-in features will remain active on unsupported platforms.

Why does Microsoft 365 drop support for older Android versions?

Microsoft limits support to the last four major versions of Android to ensure the apps can leverage modern security protocols, privacy standards, and system APIs that older OS versions simply do not possess.

Is it safe to sideload an older Microsoft 365 APK?

Sideloading older, unverified APK files from third-party websites exposes your device to significant security risks, malware, and data breaches. It is highly recommended to only use software downloaded from the official Google Play Store.

What should I do if my managed company device is stuck on an old Android version?

If your company-issued device cannot be upgraded to meet Microsoft 365's minimum requirements, contact your IT department. They will need to either authorize a hardware replacement or provision a supported alternative office application for your workflow.
