Why does onedrive not always save markings I made on a PDF?

Hello

I am Abdal and I would be glad to help you with your question.

There are a few possible reasons why your highlights might be disappearing when you close and reopen a PDF file. Here are a few things you might try to troubleshoot the problem:

Make sure you're using a compatible PDF viewer: OneDrive should work with most PDF viewers, but it's possible that you might be using one that doesn't fully support the highlighting feature. Try using a different PDF viewer, such as Adobe Acrobat Reader, to see if that helps.

Check your OneDrive sync settings: If you have OneDrive set up to sync your files automatically, it's possible that the changes you made to the PDF file might not have been fully synced before you closed it. To check your sync settings, open the OneDrive app and go to the "Account" tab. Make sure that "Auto save" is turned on and that you have a stable internet connection.

Check for any issues with the PDF file itself: It's possible that there might be something wrong with the PDF file itself that is causing the highlights to disappear. Try opening the file in a different PDF viewer or on a different device to see if the problem persists. If the issue only occurs in OneDrive, it might be worth reaching out to IT admin of your educational institute for further assistance as the university accounts are managed by them.

I hope this information helps.

Regards,

Abdal
