I stumbled upon the answer to my problem and it was quite simple. In Outlook 10, under File, Account Settings, the Email tab shows the primary email account which is by default the primary data file. Under the Data Files tab you can click on any of your other data files for which file you want Outlook to start in. I simply changed it to my Hotmail account and voila, the Hotmail calendar and appointments appear in the right-hand panel. No longer any need to move/duplicate appointments. The only downside is that when Outlook starts, my Hotmail email inbox is what loads in the main window. A simple click on my Personal Folders inbox puts that email account in focus. Much, much simpler to do that rather than keeping calendars in sync.
