When I run I get this error

Windows 10, OneNote is part of the current Office 365 Or should I try the Windows 10 Version? Or should I search for the 2016 Version?

I repaired office, and now it is running, but I get a lot of errors. I will wait it to finish and then I will see. What I see is, something is generated in the target folder.

folders are created, but they are empty. And these are the errors:

I restarted Windows, restarted OneNote several times and now ti works. it looks like a communication error between powershell and OneNote

Great to see you figured it out! Hope it helps you.

Hi @SjoerdV, first of all: wonderful work on creating this, it will definitely release me from my onenote lock-in into the world of markdown notes!

I think I'm running into the same issue as @aisbergde. I'm using Office 365 & Windows 10. When I run the Powershell command, I get the following (I copied the example error log of 1 test notebook page called 'Test', which is output in the terminal):

#### Test
Error while publishing file 'Test' to docx: Exception calling "Publish" with "4" argument(s): "Exception from HRESULT: 0x80042006"

Error while renaming image file path references for file 'Test': You cannot call a method on a null-valued expression.

I think it's to do with the Onenote version. It seems to go wrong in the part where the .docx is created. I believe the error code 0x80042006 belongs to onenote, stating that something can't be found. When I opened onenote, I also didn't see the export option to a .doxc format.

After reinstalling office, I noticed now that the option to export a Onenote page to a .docx file was available, so my hopes were high, but I still got the same error.

Do you have any suggestions?

[dirkagterhuis]

ah, the thing that made a difference: I used "../targetdirectory" when I was asked to provide the target directory, but when I used the full path, it worked. Anyhow, thanks for making this!

[SjoerdV]

Great to hear you got it working and found it a useful script @dirkagterhuis, cheers!
