OneNote Searching (Indexing ?) Problem (Bug)
- Feb 11, 2026
Replying to my own post - BUT I FIXED IT! - BUT now have other problems.
Here's what I did.
First - Backed up OneNote (which I don't fully understand where, how that works)
Next - Found the Onenote location - then closed Onenote
Next - deleted all of the files in the Onenote cache
Next - Brought OneNote back up - and it came up EMPTY (with Errors)Jacked around with the Open Backups - AS WELL AS trying to use a New Notebook location
(where I had copied my Notebook files on the advice of another post).Anyway, I finally got Onenote back up and the Search function is now working and picking up recently added notes (which was the original problem).
However, WHERE AM I.
Onenote "Info" now shows 2 Notebooks (OneNote Notebooks 4 and OneNote Notebooks 2) - and the location shown for the OneNote Notebooks 4 is even worse
(https://onedrive.live.com/view.aspx?resid=C6E59%21s0bcbd9618347485ca665bf8f3012d298&id=documents&end=()&end).
OneNote is working (well, almost - another problem with the Search dropdown list showing a full path name instead of page names) - but things are still not right.
How do I get everything lined back up (notebook names, location, etc.) - plus I have a question about the locations in the "Save & Backup" Option.
Should I open another Post for these new problems.

Reffering the guidance below:
• Rebuild the Search Index: Microsoft’s official recommendation is to rebuild the index when search stops finding new content. In OneNote for Windows 10/11, this is done via Settings > Options > Search > Rebuild Index. This forces OneNote to re-scan all notes and refresh the search database.
• Limitations: Some enterprise-managed versions of OneNote (especially those deployed via Microsoft 365 with IT restrictions) may not expose the “Rebuild Index” option. In those cases, Microsoft suggests syncing notebooks fully, closing/reopening OneNote, or reinstalling the app if the index corruption persists.
• Notebook Size: Microsoft does not state a hard limit where search fails due to notebook size. Large notebooks (thousands of pages) are supported, but indexing can take longer and may stall if the cache or sync is interrupted.

Hi, for APIM product subscriptions the built-in approval flow is quite limited and usually routes through the APIM administrator flow rather than separate approvers per product. If you need team-specific approval emails, I would look at an external workflow using Event Grid, Logic Apps, or Power Automate around subscription requests, then have that workflow notify the right product owner and call the APIM management API after approva
