Siebel Server Sync Guide > Using Siebel Server Sync > About Using SSSE with Employee Records >
Bidirectional synchronization is not recommended for the Employee domain, because its use could allow end users to create unauthorized Employee records in Microsoft Outlook, and those records would be synchronized in the Siebel database for the enterprise, causing data corruption. It is strongly recommended that administrators leave the synchronization level for Employees set to the default value of Export Only.
If Employee synchronization is set to Export Only, an employee's data is exported from the Siebel Application to Microsoft Exchange at the time that you designate the Employee record for synchronization. For information about how to do this, see Designating Employee Records for Synchronization. As long as the employee remains on your Sync List, SSSE automatically exports employee record changes from the Siebel application to Microsoft Exchange.
