Hi everyone, thank you for reporting this issue. I can help you diagnose this further if you send mail to
tohe@microsoft.com and let me know the following for the PC that experienced the unexpected uninstall:
- In your registry, do you see the following path: ‘HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\OneNote’?
- And under this path, do you see a DWORD key named ‘FirstBootStatus’?
If so, what is the Data/Value of this key?
- In your Documents folder under ‘This PC’, do you see a subfolder named ‘OneNote Notebooks’?
If not, do you recall ever moving the ‘OneNote Notebooks’ folder to another location?
- Do you recall running OneNote 2016 at least once on the affected PC since the last time you installed Office or started subscribing to O365 on that PC?
Thank you for your help! My apologies for the inconvenience.
Best,
Tony
