We are using SharePoint 2013 on-premise. We use HTTPS as default protocol for SharePoint browsing.
When our users browse with IE9, open a library, click RSS, the page
/_layouts/15/listfeed.aspx will be displayed.
When user click on "Subscribe to this RSS feed" link it jumps to
feeds://xxxxxx. Notice that the protocal become
feeds instead of
feed which IE9 do not recognize ass an RSS format.
Also, even I manually change the
feed I still cannot subscribe it because the "RSS" orange button on IE9 is grey out.
What can I do to manually subscribe to SharePoint 2013 using IE9?
