I have Microsoft® OneNote® 2021 MSO (Version 2306 Build 16.0.16529.20164) 64-bit. That’s the one that comes with Microsoft Office, and not the Windows built-in version of OneNote. A few days ago my Avast Free Antivirus updated itself to 23.6.6070 (build 23.6.8271.788). After that I noticed that OneNote is taking long to synchronize. When it syncs, you can see an overlay on your notebook’s icon.

That overlay was there for about 10 s, which is unusually long. Soon I noticed, that my changes don’t sync. I opened the Notebook Sync Status dialogue, and seen the following error messages:

OneNote can’t connect to the server. Sync will resume once we connect. You don’t need to take any action. (Error code: 0xE000006B b6d09)
I closed and reopened the notebook. OneNote wanted to sync the notebook before it closes it, but since it couldn’t, it offered to copy my unsynced changes to “Misplaced Sections”, and close afterwards. It eventually copied the entire notebook to “Misplaced Sections”, but successfully closed it. After I reopened the notebook, the error message went away. I could sync. But after a day the problem reappeared.
This Microsoft thread suggested Avast causes the trouble. And indeed, if I open Avast, go to Menu > Settings > Protection > Core Shields > scroll down to Web Shield > uncheck Enable HTTPS scanning, and restart OneNote, it can sync again. If I check it again, the OneNote error comes back.

So, the newest Avast causes sync issues in OneNote. Please fix it.
UPDATE1: User galfert [url=https://forum.avast.com/index.php?topic=324344.msg1711385#msg1711385]found[/url] a better workaround. You don't need to uncheck Enable HTTPS scanning. Instead it is enough to add a URL exception.
- Menu > Settings > General > Exceptions > Add Exception.
- Enter
https://contentsync.onenote.com
and press Add Exception.
User Leo3487 claims that adding https://onedrive.live.com
as exception worked the bug around for him (but not for me). So, the exception URL may be user dependent.
UPDATE2: Since January 2024 (after half a year) the bug is fixed. See [url=https://forum.avast.com/index.php?topic=324344.msg1713818#msg1713818]my reply[/url] on this.
