MS Powerpoint(.PPTX) Document Custom properties not visible if file downloaded from google drive RRS feed

  • Question

  • I am creating VSTO MS PowerPoint plug-in in .net c#.

    Programmatically I add some custom document properties to the PPTX document and using API I upload it on Google Drive. So when I download the same uploaded file from Google drive then Document custom properties are missing.

    I observe that Powerpoint is opening the file in Protected view and I already try with following manually in powerpoint,

    1. Go to File-> Option->Trust settings and off the protected view.
    2. Enable All macros.

    but when I tried to regenerate the case then also it's not showing the Custom properties of the document if I download the file from Google Drive

    Any kind of help appreciated. what should I need to do on this so I can get the custom properties after I download the file from Google drive
