Sometimes you may wish to block out days in your diary by using planner bookings from a specific planner. Blocking out days in your diary prevents other users from trying to schedule meetings with you on these days. For example, if you keep a planner representing the days on which you are conducting interviews, then you can use this planner, or one of its keys to block out the relevant days in your diary.
A blocked out day is represented differently in each diary view. In the Daily Appointments window, the colour of the slots is shown in light grey for blocked out days. You may customise this colour according to your personal preference. In the Weekly, Monthly and Custom views, a blocked out day is represented by a red cell header. Again, you may customise this colour according to your personal preference.
For more information on customising OfficeTalk, see Customising the Display.
If a meeting organiser tries to invite you to a meeting then any days blocked out in your diary will be shown as unavailable in the Meeting window.
