Using 2013 Outlook. I shared by calendar by publishing to a WebDav server (hosted internally). 2013 will upload the .ics file 1 time to the server - it WILL NOT update the ics file.
In comparison, the same process with Outlook 2007 also uploads the *.ics file to the server.
However, when I press F9, Outlook 2013 will NOT update the *.ics file on the server, but Outlook 2007 WILL update the *.ics file EACH time I press F9.
Goal: I would like to publish the IIS Webdev server publicly and share the link http://mycalendar.fqdn/calendar/
<username>.ics to external vendors so they can see my free/busy time. BUT - Outlook 2013 will not auto-update the *.ics file, and Outlook 2007 will update.
