I have a Word 365 document with extra document properties (Document type, meeting data, etc.) in addition to the standard properties (Author, Title, etc.). These extra document properties are added by SharePoint Online with a Library with these extra colums/metadata. These properties can be viewed with Word>Info 'Show All properties' and can be used in Word>Insert/Quick Parts>Document Property.
When converting to PDF only the standard properties are shown as metadata in the PDF. I'm using the latest versions of Office 365 and SharePoint Online. This metadata is important for the PDF document for a durable access of the document in an external Archive.
I read the answer of a simular question in feb 24, 2008 "Transfer of Document Properties in Word to Document Information in PDF" on this forum: with the right versions of Acrobat and Word custom properties are transferred to PDF. What should I do to solve this issue?
