- Product
- Microsoft 365 Mobile App, OneDrive
- Device & OS
- Android
- Scenario
- Attempting to edit and save a OneDrive document on an Android phone using the Microsoft 365 app shortly after making modifications to the same file on a PC.
- Observed behavior
- The mobile app displays an error message stating that the file was not uploaded and changes cannot be merged.
Ensure your Android phone has a stable Wi-Fi or cellular data connection, and verify that you are signed into the exact same Microsoft account on both your mobile device and your PC.
Verify PC Synchronization and Check OneDrive Online
This error most commonly occurs because recent modifications made on your PC have not fully uploaded to the OneDrive cloud servers, creating a version conflict on your mobile device.
If the desktop OneDrive client is paused, disconnected, or still processing the upload, the Microsoft 365 mobile app will lock the file to prevent data loss. Forcing the sync to complete on the host PC usually resolves the mobile merge error.
On your PC, click the OneDrive cloud icon in the taskbar. Ensure it says 'Up to date' and that the specific document has finished uploading.
Open a web browser, navigate to OneDrive online, and sign in. Locate your document and check the 'Modified' timestamp to confirm it reflects your most recent PC edits.
Once the online version is confirmed, open the Microsoft 365 app on your Android phone. Go to the 'Recent' or 'Files' tab and pull down from the top of the screen to manually refresh the file list.
Tap the document to open it again. The app should now securely fetch the fully synced version and allow you to save or merge any new mobile changes.
Clear Microsoft 365 App Cache on Android
Clearing the temporary app cache can fix internal glitches that cause the mobile app to mistakenly believe a file is out of sync or failing to upload.

Frequently Asked Questions
Why does the Microsoft 365 app say 'changes cannot be merged'?
This happens when the mobile app detects a conflicting version of the document in OneDrive. It usually means an edit previously made on your PC or another connected device hasn't fully uploaded to the Microsoft servers, causing a version mismatch.
How do I force OneDrive to sync manually on my Android phone?
You can force a sync by opening the OneDrive or Microsoft 365 mobile app, navigating to your files list, and swiping down from the very top of the screen to trigger a refresh. Make sure you have a working internet connection.
Can I save the file locally if it refuses to upload to OneDrive?
Yes. If the cloud upload continues to fail, open the file menu in the Microsoft 365 app and select 'Save a copy'. Choose 'This device' to store the document in your phone's local storage until you can resolve the OneDrive network issues.
