Why are some Microsoft® Outlook® appointments rounded up or down?
Appointments in Microsoft Outlook can begin and end on any minute of the hour, but the Project Management module records time in half hour increments. Therefore, appointment times that do not begin or end in half hour increments are rounded up or down, depending upon which quarter hour they occur in.
- Minutes between :01 and :14 are rounded down to :00
- Minutes between :15 and :29 are rounded up to :30
- Minutes between :31 and :44 are rounded down to :30
- Minutes between :45 and :59 are rounded up to :00 and the hour is increased
Durations are rounded to the nearest half hour, with 30 minutes being the
minimum duration. For example, a 10 minute Outlook appointment will become
30 minutes of nonworktime in the Project Management module.
