About Creating, Modifying or Deleting an Employee
Because the synchronization level for employees is Export Only, you must add or modify employees in Siebel Business Applications. Do not add or modify employees in Microsoft Outlook. Changes made to an employee record in Microsoft Outlook are not synchronized by SSSE and are overwritten when the employee record is next updated in the Siebel application. After adding an employee in the Siebel application, be sure to designate the record for synchronization, as described in Enabling and Disabling Employee Records for Synchronization.
If you delete an employee in Microsoft Outlook only, the employee record reappears in Microsoft Outlook the next time employee records are exported from Siebel Business Applications. To remove an employee from the Microsoft Outlook contact list, do not delete the employee record in Siebel Business Applications. Instead, users must remove their names from the Sync List for that employee.
