At first glance Outlook 2007 appears to be a new look slapped onto Outlook 2003. The preferences are almost identical and the most noticeable change is Office ribbon. There are a number of subtle changes though, and one that I just found today is the ability to email your calendar to someone.

Launch Outlook and in Calendar or Folder View right click on the calendar name and choose "Send via E-mail…". A blank message will open and a dialog window with options will present itself.

You can choose which calendar to use (if you have multiple), set working hours, change the layout and choose how much detail to include. Predefined date ranges are Today, Tomorrow, Next 7 days, next 30 days, Whole calendar and the option to choose a custom range.

The Daily Schedule layout shows all of your appointments and free time while List of Events only shows appointments. Both options also attach a .ics file to the email. This one of those features that is a huge help when trying to schedule a block of time with someone, and unfortunately I've only discovered it recently.
