In Outlook 2007, I have access to my calendar and two other calendars.
Is it possible to see the other two users' calendars overlaid on each other while not seeing events from my own calendar? If so, how can I do this?
Click the 3 check boxes next to the two calendars you want to overlay plus your own calendar so that they are all checked.
Once that is done uncheck your own calendar so now only the calendars you want to overlay are checked. Then you can see the two calendars side by side in the view and click the little arrow in the title of one of the calendars to overlay both of them.
When you have multiple calendars open there should be an arrow in the title of the calendar that you can click on and push that calendar into overlay mode
