Scheduling Data Synchronization 
You schedule data synchronization based on any of the following events:
When you open or close Microsoft Outlook
When you open or close the connection between SAP Business One and Microsoft Outlook
When you schedule data synchronization, you can define the type of synchronization (allows for criteria check or not) and also choose to examine any proposed changes before they are written to the system(s).
Note
After you have scheduled automatic data synchronization, it is still possible to start a synchronization run manually by choosing, in Microsoft Outlook, or Quick Synchronize.
You have established a connection between SAP Business One and Microsoft Outlook.
In Microsoft Outlook, choose .
The SAP Business One - Synchronization Settings window appears.
Check the default settings on any of the following tabs and make any necessary changes:
On the Schedule tab, specify the fields.
For more information, see Data Synchronization Default Settings: Schedule Tab.
Choose the Save Settings button.
When the event(s) that you selected occur(s), the systems automatically synchronize new items (calendar appointments, tasks, and/or contacts) according to your default settings.
If you selected Opening Outlook or Closing Outlook and you are not logged on to SAP Business One when the event that initiates an automatic synchronization run occurs, the SAP Business One - Log On window appears. Synchronization will only begin after a successful logon. If you choose Cancel in the Log On window, the systems cancel the automatic synchronization run.
