Outlook 2007 seems to have lost the ability to print appointments in small increments. You can still do it, but you'll have to give up a few hours.
Having a hard copy of your calendar is handy, especially if you like to make notes or pencil in changes throughout the day instead of working directly with Outlook. They're also convenient to refer to in meetings when you don't have access to your system.
Printing appointment blocks in small increments, such as 10, 15, and 30 minutes use to be simple. Unfortunately, Outlook 2007 has changed the format. Now, printing 10-, 15-, and 30-minute appointments seems impossible.
Outlook 2007 allows more room for handwritten notes, but at a price. The smaller the appointment interval, the fewer hours you can print. For instance, if you want a 10-minute appointment interval, you can print only 5.5 hours. To print 15-minute appointment intervals, you can print 8.5 hours. You can still have the smaller intervals, but you'll have to sacrifice overall hours. If you need more hours, print more than one calendar.
