Solution 1Recommended

Diagnose and Clear App Cache

Identify the root cause by checking storage, verifying the network, and clearing the app cache to resolve common processing and syncing issues.

Because images upload successfully but heavier, processed formats (like OCR Word or PDF) fail, the issue often stems from local cache corruption, insufficient cloud storage, or a network timeout during file processing.

Check Available Storage

Open the OneDrive app, tap your profile icon, and verify that you have enough available cloud storage to accept the new PDF, Word, or PowerPoint files.

Verify Network Connection

Switch between Wi-Fi and mobile data. Document processing and uploading require a stable connection, and timeouts frequently occur on weak networks.

Clear App Cache

Navigate to your device's Settings > Apps > Microsoft Lens. Select 'Storage' and tap 'Clear Cache'. Repeat this process for the OneDrive app.

Reinstall Apps

If clearing the cache does not work, uninstall both Microsoft Lens and OneDrive, restart your device, and reinstall them from your respective app store.

Information to Collect for Support: If the issue persists, take note of your device model, operating system version, available storage, and any specific error messages. This information is critical if you need to contact Microsoft Support.

Seamless Document Scanning

Scan and Save Documents Directly with WPS Office

Avoid syncing issues between separate scanner and storage apps by using WPS Office. With its powerful built-in scanner, you can easily digitize physical documents and instantly save them as PDF, Word, or PowerPoint files directly to your device or cloud.

1. Open WPS Office: Launch the WPS Office app on your mobile device and tap the '+' or 'Create' button.
2. Select the Scanner Tool: Tap on the 'Scanner' icon to activate your device's camera for document capture.
3. Capture and Adjust: Align the document within the frame and capture the image. Use the smart crop tool to adjust the borders and enhance readability.
4. Convert and Save: Tap 'Export' and choose your preferred format, such as PDF, Word, or PowerPoint. The file will be saved instantly to your local storage or WPS Cloud.

Frequently Asked Questions

Why does Microsoft Lens upload images but not PDF or Word files?

Images process locally and upload quickly, whereas PDF, OCR Word, and PowerPoint outputs require server-side processing and more storage space. An interruption in the processing service or low OneDrive storage usually causes these specific formats to fail.

How do I check my available OneDrive storage on mobile?

Open the OneDrive app, tap on the 'Me' or profile icon located at the bottom right corner of the screen, and you will see your current storage usage and available free space.

Will I lose my scanned files if I reinstall Microsoft Lens?

Yes, files that have not been successfully uploaded to OneDrive or saved to your local gallery may be lost when you uninstall the app. Attempt to export them locally before reinstalling.

Can I save Microsoft Lens scans directly to my phone instead of OneDrive?

Yes. When on the saving screen, uncheck the 'OneDrive' option and ensure 'Gallery' or 'Phone Storage' is selected so the PDF or image is saved locally to your device.
