Hi All,
I am working on one of the projects and customer have a
couple of PDF documents in their organizations. They want to use this
PDF as template in the SharePoint Online environment.
I made a content type for this purpose in the SharePoint Online environment. However, when I tried to click on the New document for that PDF document as shown:
I get this error.
New Document' requires a Microsoft SharePoint Foundation-compatible application and web browser. To add a document to this document library, click the 'Upload Document' button.

I found several links as follows pertaining to this error:

Our company group policy for Internet explorer and I cannot configure any IE add on for that matter.
Any suggestion will be highly appreciated.
Thanks in advance.
