Fix Microsoft 365 App Cannot Open Existing Word Documents on Android
Question details
The user is unable to open previously edited Word documents using the Microsoft 365 app on an Android tablet, even though newly created blank documents open without any issues.
- Product
- Microsoft 365 App
- Device & OS
- Android (Galaxy Tab)
- Scenario
- Attempting to open existing Word documents synced from a computer on an Android tablet.
- Observed behavior
- Existing documents fail to load or open in the app, despite basic troubleshooting like reinstalling, signing out, and applying software updates. Blank documents open normally.
Ensure your Android device has a stable internet connection so that cloud files can sync properly, and verify that the file isn't currently locked or open on your desktop computer.
Restore an Earlier Version from Cloud Storage
Reverting to a previous version of the file can bypass file corruption or sync conflicts that might be preventing the current version from opening on Android.
If the document was edited on a computer and synced to OneDrive or SharePoint, the latest version might have encountered a sync error or contains unsupported elements.
Open a web browser on your computer or tablet and log in to your OneDrive or SharePoint account.
Navigate to the folder containing the Word document that refuses to open on your Android device.
Right-click the file (or tap the three-dot menu icon on your tablet) and select 'Version History' from the context menu.
Find an older version from before the issue started, click the three-dot menu next to that version, and select 'Restore'. Wait for it to sync to your tablet.
Open the Document in Word for the Web
Using the web-based version of Microsoft Word serves as a quick workaround when the dedicated mobile app fails to open specific files.
Contact Your Organization's Microsoft 365 Administrator
If the issue persists and involves a school or work account, administrators can collect diagnostic logs and contact Microsoft Support for a backend fix.

Frequently Asked Questions
Why do new blank documents open but existing ones fail in the Microsoft 365 app?
This discrepancy usually indicates an issue with file synchronization, a corrupted app cache, or unsupported content (like complex macros or specific formatting) within the existing document that the mobile app struggles to render.
Will clearing the Microsoft 365 app cache fix the document loading issue?
Sometimes. You can try going to your Android Settings > Apps > Microsoft 365 > Storage, and tapping 'Clear Cache'. This removes temporary files that might be causing the app to freeze when opening existing documents.
Can I use an alternative app if Microsoft 365 refuses to open my files?
Yes. If you urgently need to access your documents, you can use highly compatible alternative office suites like WPS Office for Android, which can directly open .docx files natively.
