If I upload an ASPX file to the documents library in a regular SharePoint site, it renders properly when a user clicks on the file.
If I do the same for an ASPX file uploaded to the documents library in a SharePoint site that backs an Office 365 Group, the ASPX file is not rendered, but downloaded instead. Is there any way to get SharePoint to render ASPX files?
- Setting the "Default open behavior for browser-enabled documents" in the advanced library settings to "open in the browser" does not help.
- A SharePoint site behind an Office 365 group has a Pages library that obviously allows ASPX files. I am unable to upload to that library via the browser, but I suspect I could do this via code. I wonder if there is some specific setting on the document library that turns on this behavior. If so, I couldn't find it.
- I am aware of permissive file handling and that the default value for this does not allow rendering of HTML files. However, this does not appear to affect ASPX files. Interestingly, I am now unable to perform a
set-spotenant -PermissiveBrowserFileHandlingOverride $truein my test tenant. I get back a message indicating that "Permissive browser file handling setting is deprecated and can't be enabled."
