Scenario: Server1 Exchange 2003 with SP2 Lotus Notes Connector Server 2 Lotus Domino Server 6 Bridgehead 1. Configured that when directory synchronization, contacts will be created on the Active Directory 2. Some parameters (based on the mapping table) of Exchange and Lotus Notes (ex: Country) to be also synchronized. 3. Initiated synchronization (successful) contacts were created on the Active Directory (Notes to Exchange) and also from Exchange to Notes 4. Here's the problem: When the "Manager" field was added to the mapping table (for synchronization purpose, Exchange to Notes) and then initiated synchronization, existing contacts from Active Directory that has a defined Manager field from Lotus Notes was deleted/gone on the Active Directory Users and Computers 5. Also simulated this issue on a lab and still the same behaviour occured (Notes to Exchange Synchornization = deleted existing contacts from the ADUC) Do you have a copy of really customized mapping table (consisting of the manager and city field)? Thanks much
