Exchange 2000 Server - Select a Replication Direction

Coexisting with Previous Versions

Select a Replication Direction

For recipient Connection Agreements, you can choose the direction of replication based on the directory management requirements of your organization. You can select one-way or two-way replication. During one-way replication, directory information is replicated from Exchange to Windows or from Windows to Exchange. During two-way replication, directory information is replicated to and from both directories.

Note All public folder Connection Agreements require two-way replication. The direction is automatically selected when you create a public folder Connection Agreement, and you cannot change it.

For more information about ADC one-way and two-way replication, see Microsoft Exchange 2000 Server Planning and Installation.

To select a replication direction:

If you have not yet opened the Connection Agreement in Active Directory Connector, do the following:
1. On the Start menu, point to Programs, point to Administrative Tools, and then click Active Directory Connector.
2. In the details pane, double-click the Connection Agreement for which you want to set a replication direction
3. .
On the General tab, under Replication direction, click one of the following replication directions:
- To perform a two-way replication, click Two-way.
- By default, objects are first replicated from Exchange to Windows. To update the Exchange directory first, on the Advanced tab, in Initial replication direction for two-way Connection Agreements, select From Windows.
- To update the Windows directory, click From Exchange to Windows.
- To update the Exchange directory, click From Windows to Exchange.

Note To have the option of adding Exchange mailboxes when creating new users in Active Directory Users and Computers, you must configure a two-way Connection Agreement or a one-way Connection Agreement from Windows to Exchange. A one-way Connection Agreement from Exchange to Windows does not provide you with the option of adding a mailbox for the user because one already exists.
