Dear Alex,
Thank you for reaching out to us. I understand how inconvenient it must be to have your OneNote on Android showing as "read-only" for over a month, especially when it works normally on your PC. I’m here to help you resolve this issue.
To assist you better, could you please help us with the following details?
- Account Type: Are you using a personal Microsoft account (e.g., Outlook.com, Hotmail.com) or a work/school account provided by your organization?
- Notebook Source: Is the notebook stored in OneDrive, SharePoint, or another location?
- Sync Status: On your Android device, do you see any sync errors or warnings in OneNote?
- App Version: Have you updated the OneNote app recently? If not, could you try updating it from the Google Play Store?
- Permissions: Are you the owner of the notebook, or was it shared with you? If shared, do you know if your permissions were changed recently?
Once we have this information, we’ll be able to guide you through the appropriate steps to restore full access on your Android device.
Thank you again for your patience and cooperation. We look forward to resolving this for you soon.
Warm regards,
Sophie N - MSFT | Microsoft Community Support Specialist
