An Event is any single occurrence or activity which may take place on a single day or may be repeated over a number of days. Events may be either public or personal, which means that they may be used to keep personal events such as birthdays and anniversaries for individual users and they may also be used to record workgroup wide data such as public holidays, company holidays and other company events.
Once defined, events may either be shown in the Background Activities window or shown through onto the Appointment windows. In this way they achieve the same end result as a planner booking but without the need to define a planner and a set of planner keys.
Events may also be used to block out users' diaries. This can be useful if, for example, you wish to define a set of public holidays and you wish to ensure that meeting organisers will not accidentally arrange meetings on these days.
