Dear Najat,
Thank you for reaching out and providing detailed information about your missing Sticky Notes in the OneNote app on your Android phone. I understand how concerning it is to lose your notes, and I’m here to help you explore ways to recover them.
Based on your description, it seems the notes may not be syncing properly because the Sticky Notes feature in OneNote is designed to work best when signed in with a Microsoft account and synced across devices. Since you mentioned you started signing in only after the notes disappeared and that syncing is not currently active, this might be why your notes are not showing up.
Here are some suggestions to help you troubleshoot and possibly recover your Sticky Notes:
1. Check the Sticky Notes App on Your Android Device
- Microsoft Sticky Notes is a separate app from OneNote. Please check if you have the Sticky Notes app installed on your Android device.
- If not, you can download it from the Google Play Store here:
Microsoft Sticky Notes - Google Play Store
- Open the Sticky Notes app and sign in with your Microsoft account to see if your notes appear there.
2. Sync Your Notes Properly
- Ensure you are signed in to the same Microsoft account in both the Sticky Notes app and OneNote app.
- Sticky Notes created in OneNote sync to the Sticky Notes app and vice versa, but only when signed in with the same account.
3. Access Sticky Notes via Web
- You can also try accessing your Sticky Notes online to check if your notes are stored in the cloud:
https://www.onenote.com/stickynotes
- Sign in with your Microsoft account and see if your notes are available there.
4. Check for App Updates
- Make sure both the OneNote and Sticky Notes apps are updated to their latest versions on your Android device.
5. Backup and Export Notes in the Future
- Once your notes are recovered, consider backing them up or exporting them regularly to avoid data loss.
