I published a calendar from Outlook to office.microsoft.com; a feature in Outlook 2010. I then subscribe from calendars.office.microsoft.com to my calendar in Outlook.com (Live.com). Calendar refreshes can take weeks if they ever get refreshed at all.

If I go into Outlook.com and re-subscribe, I continue to get the same results; it won’t refresh.  I do get different results based on whether http or https is used (it converts the webcal and webcals to http and https respectively). The http result has many missing items; perhaps because it is an older version. It seems as though it’s a caching problem or a connection problem.

All changes made in Outlook do in fact get published to office.microsoft.com as is verified in a Google Calendar subscription which does not have the same issue.
