I'm trying to install a new Exchange 2007 server in order to migrate users off of Exchange 2003 but the Hub Transport Role fails to install with the following error: Read only MultiValuedProperty does not support this operation. I'm installing from the SP3 files and the server is Windows 2008 R2. I've tried installing onto a Windows 2008 server and have also tried installing from the SP1 files with the same result. I saw posts about the same error happening with the CAS role ( http://tinyurl.com/2eymads ) and have tried the fix mentioned but still get the same error. The ExchangeSetup.log has the following entries: [8/17/2010 9:09:06 AM] [1] Setup failed previously while performing the action Install. Looking for the failed task with ID bdcb76b3.

Hi, Do you have Exchange Server 2003 in the current network? Or do we have Exchange Server 2003 before? The problem could occur when the Default Offline Address Book was moved from the E2K3 server to an E2K7 server by using the E2K3 ESM. This prevented us from populating an attribute that is checked by the Exchange setup. If the OAB is initially moved by the E2K7 EMC (or by PowerShell) to an E2K7 server, we populate the msExchVersion attribute. We can solve the problem via the following steps: Use ADSI Edit to manually populate the msExchVersion attribute with the correct value on the OAB we had moved using the E2K3 ESM. 1. The AD object for the OAB is found at: Configuration -> CN=Services -> CN=Microsoft Exchange -> CN=<organization> -> CN=Address Lists Container -> CN=Offline Address Lists 2. Get properties of the OAB that was moved. 3. Set the value of msExchVersion to 4535486012416. I hope this will help you. Regards.

Hi Shafaquat, Thanks for your reply but I had already tried setting the msExchVersion on the Defualt OAB and it did not help. Any other suggestions? Thanks, Greg

I found the answer to this issue myself and thought I would share it. Hopefully it will save someone else some time and pain in the future. Open ADSI Edit Navigate to Domain -> DC=your,DC=domain -> OU=Microsoft Exchange Security Groups Right click CN=Exchange Servers and select Properties Change the msExchVersion attribute to 4535486012416 The Hub Transport role will install correctly now. Thanks, Greg
