We are using the Microsoft APIs to download files from Sharepoint while immediately converting them to PDF on the fly.
End of July, this was still working fine; this weekend we run the same logic again and it fails consistently with this error:
[406] Error from Office Service. Url=https://euc.wordcs.officeapps.live.com/document/export/pdf HttpCode=UnsupportedMediaType
The error code is "OfficeConversion_DocumentProtected" but there's - as far as I know - no special protection enabled on the document...
When not exporting to PDF, it works fine to download the file. Any clues?

I first save the word doc into SP then immediately request a PDF version of it.
It is as if the newly saved doc is still busy applying properties although the doc id after creation has already been returned.
I now have a service running retrying each minute until there is a success. This seems to work. -
