CAUSE

This issue may occur if replication for the Messaging Database (MDB) on the server has been turned off.

You can turn off replication by using the Replication registry entry with a value of 0. By default, replication occurs if the key does not exist.

This issue may also occur in the following scenarios:

Remote procedure call (RPC) errors occur on another Exchange 2000 computer in the site, and the Recipient Update Service does not stamp the proxyAddresses public information store object. After you restart the server that has RPC errors, the Recipient Update Service stamps the public information store object on the new server and replication occurs.
An invalid GatewayProxy address generator exists, and the Enterprise Recipient Update Service does not stamp the proxyAddresses public information store object. After you remove the invalid GatewayProxy address generator and restart the Recipient Update Service server, the new public folder information store is stamped and replication works as expected.

RESOLUTION

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To resolve this issue, delete the Replication registry entry for this Messaging Database (MDB) from the following subkey:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\MSExchangeIS\<servername>\Public- <GUID of Public Store>

Note Do not delete the Replication entry if you are using specific values for replication that are overriding the default values, and you want to continue using the specific values. You may want to compare this entry against working servers to verify that they do not have this entry set, or it is set to a different value.

Use the following table to determine the decimal values for the Replication registry entry:

0	Replication is disabled.
1	Replication is enabled. (Use registry variable defaults. This has the same affect as deleting the entry.)
2	Replication is enabled. (Use registry variable overrides.)

Note To enable the rest of the override settings for public folder replication, set this value to 2.
