Exchange 2003和Exchange 2007

　　最近我们看到很多Exchange 2003和Exchange 2007之间的公用文件夹复制问题. 当发生这个问题时会有下列现象:

　　1.　　Exchange 2007的邮箱无法看到Exchange 2003上的公用文件夹

　　2.　　公用文件夹复制邮件全部堵塞在Exchange 2003上的Messages with an unreachable destination队列

　　3.　　在Exchange 2003服务器上,你可能会看到下面这个事件:

　　Event Type: Warning

　　Event Source:　 MSExchangeTransport

　　Event Category:　　　Routing Engine/Service

　　Event ID:　　951

　　Description:

　　When sending mail to following address exchange2007name.domain.com.5B2DCAE3-0882-1148-8DEB-B36F641F9E2B, we have found the connector with target domain *.5B2DCAE3-0882-1148-8DEB-B36F641F9E2B matching destination address exists in DS. However, we have no way of getting there. Possibly, you need to check your topology and add appropriate connectors among Routing Groups.

　　这个问题发生的原因是在Exchange 2007 路由组和Exchange 2003 路由组之间没有Routing Group Connector. 在Exchange 2007安装时,会有个选项要求你选择Exchange 2000/2003 Routing Group Connector桥头堡服务器. 假若你跳过这个选项, 系统就不会帮你自动创建Routing Group Connector.

　　注意 第一个Routing Group Connector 只会在安装第一个Exchange 2007 Hub Transport Server 角色时创建.

　　要解决这个问题,你可以用Exchange Management Shell手工创建Routing Group Connector. 例如,下面的例子可以创建一个cost是100,允许public folder referrals的Routing Group Connector:

　　New-RoutingGroupConnector -Name "Interop RGC" -SourceTransportServers "Ex2007Hub1.contoso.com" -TargetTransportServers "Ex2003BH1.contoso.com" -Cost 100 -Bidirectional $true -PublicFolderReferralsEnabled $true
