Control the way in which your Agenda reconciles on-line and off-line Entries in this section. For example, if you made changes to an off-line Entry that has also been changed on-line, and then uploaded, your Agenda can either update the on-line Entry or show the Reconciliation dialog box, letting you decide on an Entry-by-Entry basis.
Select Update off-line Agenda after upload to make sure your
On-line and Off-line Agendas are identical after each upload.
