If this setting is On, the DME client will initiate synchronization of the enabled resources (e-mail, calendar, etc.) according to the schedule specified below.
If this setting is Off, the synchronization of resources relies on client-initiated sync (pull, where applicable), manual synchronization, or push notification from the mail system. If On, the scheduled synchronization is based on the following settings:
- Interval (min.)
In this field you can specify how often scheduled sync. should be executed. By default, the permitted range is from 0 (never) to 99999 minutes, but you can change this. Note that the load on the DME server and the drain on the device batteries will increase, the lower a number you specify. Recommended value: 180 minutes.
- Start time (hours:minutes)
In this field you can specify the time of day at which the scheduled sync should start. You can for instance choose to start scheduled sync at 8 in the morning. Use together with the fields End time and Run on weekends.
- End time (hours:minutes)
In this field you can specify the time of day at which the scheduled sync should stop. You can for instance choose to not sync after your regular work hours. Use together with the fields Start time and Run on weekends.
- Run on weekends
If this setting is On, the client will perform a scheduled sync in the weekend also, during the interval specified by the Start time and End time settings.
