Adjusting Time Increments

By default, your Outlook Calendar is divided into 30-minute time increments. Depending on your needs, this may or may not be the most efficient. You can adjust the time increments to something that works best for you (e.g., 15 minute increments).

NOTE: Smaller increments can expand the view, but you may not be able to see the entire day at once.

You can alter the displayed time increments using the View menu.

1. On the Navigation pane, click CALENDAR
   The Calendar view appears.
2. From the View menu, select Current View » Customize Current View…
   The Customize View: (Current View) dialog box appears.
3. Click OTHER SETTINGS…
   The Format (Current) View dialog box appears.
4. From the Time scale pull-down menu, select an appropriate increment
5. Click OK
   The Format (Current) View dialog box closes.
6. Click OK
   Your Calendar view is adjusted to reflect the new increments.

You can alter the displayed time increments with fewer clicks by using the right click method.

1. On the Navigation pane, click CALENDAR
   The Calendar view appears.
