Microsoft Outlook - Be Considerate And Block Off Your Calendar When You're Away From The Office (Outlook 2000/2002/2003)
If you're on vacation, on a business trip, or otherwise unavailable for meetings, it's a good idea to block off these days and times on your Outlook Calendar. This way, others who have access to your free-busy times in Outlook don't try to schedule meetings with you for these times you're actually available.
Open your Calendar and click on a day that you'll be unavailable. Open a new Appointment form, and select the All Day Event check box. Select Out Of Office from the Show Time As dropdown list. Enter the effective start and end dates in The Start Time and End Time text boxes--the event can span multiple days. Enter a subject, and then click the Save And Close button.
