A reader recently asked how to set a different calendar as default: "I have a Google Calendar in my Internet Calendars section of Outlook 2007. When I start Outlook 2007 the calendar is by default not active. I do not use the built-in Calendar under "My Calendars" but instead only use/need the Google Calendar under "Other Calendars". Can I set up Outlook 2007 to (a) enable/display my Google Calendar at startup and (b) disable/do not display the Calendar under "My Calendars"? When I start Outlook I have already set the start page to Calendars instead of Outlook Today."

You can't get rid of the default calendar and you can't set the Google calendar as default but you can have any calendar you want active when you first open Outlook, provided you want the calendar folder to load when you open Outlook. Go back into Tools, Options, Other, Advanced... and pick the Google calendar as the start up folder. When you switch to the calendar folder this calendar will be active (until you deselect it).
