SharePoint 2013: Opening Office Document (Excel) using https


  • Hello,

    I have two issues with SharePoint web application, where FBA (claims-based authentication) is configured at this web application,

    First issue:

    Excel documents whether they are in xls or xlsx, they prompt for authentication when opening the file, I've added below entries to web.config file, but still prompts for authentication

      <requestFiltering allowDoubleEscaping="true">
        <verbs allowUnlisted="true">
          <add verb="OPTIONS" allowed="false" />
          <add verb="PROPFIND" allowed="false" />

    I've also disabled the client integration and set it to "No" from Central Administration.

    Second issue

    In IE, any file cannot be opened using https, it throws a message saying "Sorry, we couldn't open https://site/subsite/doclib/excelfile.xlsx"

    Any advice would be much appreciated.
