I was made aware of the fact that the rss2 feed produces bogus publication dates in Outlook 2013. I went on to check the feed data and saw that it produced RFC 822 conform pubdates so that shouldn’t be a problem. Is RSS 2.0 not that widely supported? Both the RSS 1.0 and the ATOM feed produce correct results in Outlook and so on. I am considering to limit the feeds to those two iterations leaving RSS 2.0 out of the picture from now on. Any thoughts?
