I have an ICS calendar hosted at http://efw27.user.srcf.net:8080/IA/lent/178-180.ics.

Google calendar is just fine with it, but when I try to subscribe to it on calendar.live.com, I get the error:

What's wrong with the calendar?

EDIT: If I download the calendar and host it at mysite.com/cal.ics, outlook is fine with it. Looks like a refusal to accept port numbers.

Turns out outlook blindly drops the port number and replaces it with the default - http://site.com:port/ -> http://site.com:80/ –  Eric Oct 31 '14 at 13:37
