SUMMARY
The InterOrg Synchronization tool is available in the Microsoft BackOffice
Resource Kit, Second Edition. Microsoft Product Support Services will use
commercially reasonable efforts in addressing all support problems. Please
do not confuse the InterOrg Synchronization tool with the InterOrg
Replication utility for public folders, which is available on the Microsoft
Exchange Server version 5.5 Service Pack 2 compact disc.
This tool allows multiple Microsoft Exchange Server organizations to synchronize the contents of their directories.
The connector works hierarchically, with a master service running in the master organization, and multiple requestor services running in the branch organizations. The Exchange Server computer of the master organization collects and distributes all of the directory changes from the branch organizations.
The requestor service in each branch organization collects any changes that have occurred in the directory of that organization and exports these changes to the master service. At the same time, the requestor receives the updated directory information from the master service. When the master agent receives updates from a requestor, the master agent creates a new entry and assigns it an Update Sequence Number (USN) that is greater than the USN for the last entry processed. Each requestor stores the largest master USN that it has received, so it requests only new entries to be posted to the global directory. The master and requestor services communicate using the Exchange Server Internet Mail Service. Therefore, you must have an SMTP infrastructure in place prior to configuring this service.
Processing Events
On a scheduled basis, the requestor service generates a mail message for the master service. This message includes any changes that have been made to the directory of the requestor organization, and the most recent (largest) master USN of the requestor. Note that the requestor exports only the directory information that is maintained on the General property page of an address book entry. That is, the requestor service does not export the information available in any of the custom attributes.
When the master receives a mail message from a requestor, it updates the master database with the appropriate changes, and then sends a reply message to the requestor. The message to the requestor contains all updates to the master database that have a higher USN than the one that was sent by the requestor. Although the master agent processes all requestor messages immediately, changes may not replicate throughout the entire system for at least 24 hours.
