Yikes, that's pretty sad. I guess I'll look at some other cloud service for a shared calendar, too bad, seems like Microsoft should have had the best shot at working with other Microsoft products, but oh well.
Thanks for the reply,
I have Outlook 2013 on the desktop, and an office.com account setup in it (not the primary account though) and configure to use Exchange ActiveSync.
If I select the outlook.com calendar in Outlook 2013, and add an event, it never gets sent up to outlook.com. Any thoughts on what I could be...
