Use the Microsoft 365 App as an Alternative Scanner

Bypass the Microsoft Lens synchronization failure by using the built-in scanner within the Microsoft 365 mobile app, which offers more reliable OneDrive integration.

Since Microsoft Lens and the Microsoft 365 app share similar scanning technologies, the 365 app can serve as a direct replacement. Because the Microsoft 365 app is inherently integrated with your Microsoft account and OneDrive, it often avoids the upload glitches currently affecting the standalone Lens app.

Download and launch the Microsoft 365 mobile app on your smartphone or tablet, and sign in with your Microsoft account.

Access the Capture Feature

Tap the 'Capture' or 'Create' button located at the bottom navigation bar of the application.

Scan the Handwritten Pages

Choose the scanning option, align your device camera with the exam pages, and capture the images.

Save to OneDrive

Reliable Sync: Using the centralized Microsoft 365 app generally offers a more stable upload path to OneDrive than the standalone Microsoft Lens app.
