OneNote cannot sync (Error code: 0xE000006B b6d09)

For a permanent solution I hope that Microsoft and Avast can work together to formulate a solution. Without knowing the inner workings of OneNote and Avast it is almost impossible for me to determine if the blame is on one company or the other. I can see the issue being either Microsoft OneNote implementing a poor use of HTTPS to sync or perhaps Avast doing something too deterministic and limiting that prevents Microsoft from using HTTPS in an application to use as a sync conduit.

Therefore, I’ve also reported the issue to Microsoft. Unfortunately, it is a blind request as no case gets created when you contact Microsoft about this type of issue. The Microsoft Support Agent I first contacted said that the only way to file a report was to open a feedback report which is like I said a blind submittal.

This issue until properly addressed is unfortunately going to affect uninformed users that will not necessarily know that their antivirus and its default settings are the cause of the incompatibility and creating the OneNote sync issue.

True, we cannot tell for sure, whether Avast or Microsoft needs to fix the bug. So here are two counters. This time in years.

After half a year someone fixed it. Thank you! Although a little bit late. :slight_smile:

Now I have no exceptions in Avast, Enable HTTPS scanning is on, and OneNote syncs between computer and phone in both directions. I have no error messages in OneNote Notebook Sync Status.

byy the time from last reply, seem it was an avast patch
And sure, culprit was avast, as no problem with other AVs
