We have installed Exchange 2007 SP3 HUB Server in Windows 2008 Server in an Existing Exchange 2007 organization. The active directory rangeUpper value is 14622 which is Exchange SP2 schema. In the new HT server we are unable to create a new receive connector. As per Microsoft technet I found the AD schema needs to be upgraded to SP3. Is there any way to roll back the Exchange SP3 to Sp2 and configure receive connectors. Please suggest.Ahmed Ali

Is there any way to roll back the Exchange SP3 to Sp2 and configure receive connectors. Please suggest. Ahmed Ali No, It's not possible to uninstall an Exchange Service Pack What you should do is to patch your other servers. Note: A CAS Server should always be the upgraded before HUB and MBSP2 hasn't been supported for over a year now.Martina Miskovic

Thanks Martina.Ahmed Ali
