The UseRUSServer parameter does not work if an administrator has specified an RUS server on a target mailbox server

On a Microsoft Exchange Server 2007 with Service Pack 1 (SP1) server, an administrator can run the Move-Mailbox command together with the UseRUSServer parameter to specify a different Recipient Update Service (RUS) server to be used. However, if the administrator has already specified an RUS server on the target mailbox server, that RUS server is used instead of the RUS server that is specified in the UseRUSServer parameter. When this issue occurs, if the target RUS server is not available, the Move-Mailbox command fails because the RUS server that is specified in the UseRUSServer parameter is not used.

To resolve this problem, install Update Rollup 7 for Exchange 2007 Service Pack 1. For more information about Update Rollup 7 for Exchange Server 2007 Service Pack 1, see the following Exchange Help topic: For more information about how to obtain the latest Exchange service pack or update rollup, see the following Exchange Help topic:
