Hi. Got this error when trying to install Exchange 2007 SP1 (windows 2008 SP2): Property IsClientAccessServer cannot be set on this object because it requires the object to have version 0.1 (8.0.535.0) or later. Current version of the object is 0.0 (6.5.6500.0).

Hello You will have to prep the forest and domain manually if not try it and re-run the setup again. Thanks Mhussain

Windows 2008 is new/first domain in network, I will prepare the forest and domain??

If it's a new deploy, why not install SP3 directly? http://www.microsoft.com/downloads/en/details.aspx?FamilyID=1687160b-634a-43cb-a65a-f355cff0afa6&displaylang=en Prereqs: http://technet.microsoft.com/en-us/library/aa996719%28EXCHG.80%29.aspx Release notes (read them ) http://technet.microsoft.com/en-us/library/ff607233%28EXCHG.80%29.aspxJonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hi, If this is a new deploy, please paste the related information of your ExchangeSetup log. You can find it in this path: The system disk\ExchangeSetupLogs\ExchangeSetup Also I think Jonas’s suggestion is good. If it is a new deploy, we recommend you to install Exchange 2007 SP3 directly. Thanks, Evan

Any update on this ? Thanks Mhussain
