A family of Microsoft products that enable users to capture, organize, and reuse notes electronically.
Hi Kartik and all,
About the root cause: not clear yet. I've talked to 2 support staff from Microsoft on the phone and 4 chats. Thanks to all the Microsoft staff involved, especially Vikram and Terrence Y who have been very helpful.
At the end all my OneNote files are syncing properly now, and I didn't have to restore a backup file, but no answer on the question what caused the issue, or how the issue was solved (by them). Maybe that will come.
The only change that happend on my side, is an update of my OneNote office client to version 16.0.7167.2036.
An updated summary of lessons learned:
- Use OneDrive for business if you can and put your OneNotes there. Although also on a regular OneDrive, files can be restored to a previous version.
- Backup your OneNotes frequently (every 12 hours?). See File > Settings > Backup.
- When you are in touch with a MSFT support person via chat, ask for a case number and an url to return to the chat when connection is lost. Happend to me 3 times...
- When your OneNote has sync issues, especially with error code 0xE4020017, do not panic and do not start with closing your local OneNotesfor instance. That way you will only loose your last edits.
- Only think about closing your local version when you've opened the online version and there all sections are accessible and in good condition.
- Online support via Twitter @microsofthelps did not give much results. Maybe I should have gone into DM with them?
- If the online version of your OneNote is broken, then COPY pages (or sections) from your local (also corrupt?) notebook into a new local OneNote. You can do this page by page and monitor synchronisation after each.
That is a safety and rescue operation. You can do this also on other devices that have the same OneNote in local version. It might be good to cut their internet connection during that operation. 8. Check also this document "Troubleshoot synchronization errors in OneNote 2016 for Windows". 9. Keep enjoying the power of OneNote. It still is a great product.
Best regards from Belgium.
All's well that ends well...
But I'm still curious about what caused all this...
