About Synchronizing Employees
Bidirectional synchronization is not supported for the Employee domain because its use could allow users to create unauthorized employee records in Microsoft Outlook, and to synchronize those records with the Siebel database for the Enterprise, causing data corruption. The synchronization level for employees must either be set to the default value of Export Only or to None.
If Employee synchronization is set to Export Only, an employee's data is exported from Siebel Business Applications to Microsoft Exchange at the time that you designate the employee record for synchronization. For information about how to do this, see Enabling and Disabling Employee Records for Synchronization. As long as the employee remains on your Sync List, SSSE automatically exports employee record changes from Siebel Business Applications to Microsoft Exchange.
