Question details
The user needs to retrieve lost handwritten annotations made on a PDF using a tablet application.

- Product
- OneDrive
- Device & OS
- not provided
- Scenario
- Adding handwritten notes to a PDF document saved in OneDrive via a tablet application.
- Observed behavior
- Handwritten annotations disappeared, leaving only the first two words, and the missing changes are not recorded in the OneDrive version history.
Immediately stop editing or saving the affected PDF file to prevent accidental overwriting of any cached versions on your device.
Check OneDrive Web and Local Storage
Verify if the file synced completely to the cloud or if a cached version remains locally on your tablet.
Often, synchronization interruptions prevent tablet apps from uploading the latest annotations. The missing notes might still exist in a temporary local cache or under a different Microsoft account.
Open a web browser, navigate to OneDrive.com, and view the PDF online to see if the handwritten notes successfully synced to the server.
Ensure you are logged into the exact same Microsoft account on both your tablet's application and the web browser.
Open your tablet's file manager and look for a downloaded or cached copy of the PDF within your 'Downloads', 'Documents', or app-specific folders.

Contact OneDrive Support
If version history and local storage fail to reveal the notes, Microsoft support can investigate potential server-side sync failures.

Frequently Asked Questions
Why did my handwritten notes disappear from the OneDrive PDF?
This usually occurs due to a synchronization interruption, network dropout, or an application failure before the device could successfully upload the handwritten data to the OneDrive servers.
Can I recover previous versions of a PDF in OneDrive?
Yes, you can right-click the file on OneDrive.com and select 'Version history' to restore older versions. However, if your recent edits never reached the server, they will not appear in this history log.
Are cached PDF files stored temporarily on my tablet?
Yes, many applications store a temporary cached version in the device's app data. Using a file manager app to search for recently modified PDF files might help you locate this offline copy.
