Hi All,

I am facing an issue with a new Exchange 2007 Installation in a coexistence environment with Exchange 2003. I had earlier installed Exchange 2007 after making all the necessary changes in the domain. Domain already has an Exchange 2003 server.
Here is what I did in order
1. Created Windows 2003 x64 Standard Edition with SP2.
2. Installed Dotnet Framework 2.0 and Windows Powershell.
3. Ran following commands on the new Windows 2003 machines in following order:
setup /preparelegacyexchange permissions
setup /prepareAD
setup /prepareDomain
4. After that I installed the following roles on the server: Mailbox, Hub Transport, Client Access.
After the installation was complete, I tried to access the OWA site of Exchange 2007 and that didn't work. There were some issues with the IIS configuration, so I removed it and reinstalled, I also had to remove the Client Access Role and then installed it back. But that didn't fixed the issue.
So i uninstalled Exchange 2007 completely but running the setup. In the process of removing it, I removed the routing group connectors from Exchange 2003 System Manager which were created by Exchange 2007 setup for mailflow. and deleted the public folders directly from Domain Configuration partition as exchange Management console wasn't letting me remove it. After it was removed. I fixed the IIS issue. and reinstalled everything (Exchange 2007). But the Hub Transport Role didn't work. I thought there might be some issue with the registry of the Windows Server that might be conflicting with the Exchange configuration.

So I removed it again using the same procedure that I did before, and rebuilded the entire Windows Server system and installed Exchange 2007 from scratch. Now again the Hub Transport Server is not working. The Microsoft Exchange Transport Service is faling again and again.

I am getting the following three Error messages in Event Viewer:
______________________________________________________________
Event ID: 1009

The Microsoft Exchange Mail Submission Service is currently unable to contact any Hub Transport servers in the local Active Directory site. The servers may be too busy to accept new connections at this time.

Event ID: 491

edgetransport (5944) Transport Mail Database: An attempt to determine the minimum I/O block size for the volume "D:\" containing "D:\Program Files\Microsoft\Exchange Server\TransportRoles\data\Queue\" failed with system error 5 (0x00000005): "Access is denied. ".  The operation will fail with error -1032 (0xfffffbf8).
__________________________________________________________

I performed these steps as the Hub Transport Service is failing again and again:

http://technet.microsoft.com/en-us/library/bb125177.aspx 

I created the queue database again at a new location. One thing that I noticed is that in the default location of the Queue Database there were no files by name of  "Mail.que and Trn.chk " where as according to the document it should be there.
Even after creating a new queue database directory these two files were not created. So I am actually stuck at this point. I have an Exchange 2003 in working condition, and have an Exchange 2007 server on which the Microsoft Exchange 2007 service stops automatically after five minutes and it is not able to send and receive emails at all. I am able to start the service from the services panel but it will fail as soon as I will try to send an email from Exchange 2007 Owa or Outlook 2007. before it fails a warning message is generated in the Event Viewer indicating that the Mail submission service is currently busy and could not accept emails at the moment, after this error message, the above mentioned three error message comes up and I have Microsoft Exchange Transport Service in stopped condition.

Please help in this regards, every help would be highly appreciated. I know I have written a pretty long topic. But I want to provide as much information as I can to resolve this issue.

Thank you very much.

So at the point where the hub transport failed you removed exchange and resinstalled the OS and then reinstalled exchange and the same problem persists?  Did you use the same name for the server?  After you install windows, do you do anything special to the access control lists on the hard drives?  How about after installing exchange?

To expirament, I would first try to remove the hub transport roll from the server you're working on and then install just the hub transport toll onto another server.  Exchange should find the hub transport server and use it.  You will probably have to recreate the 2003 to 2007 connector manually since you deleted it.

Sorry, for the delay in reply. I did this however, it didn't help at all. I was still stuck with the same issue. But later on I figured out it was a permission issue. On a hub transport server we need to grant access to the network service on the transport Queue Directory (Their some other folders too). I did that but that didn't helped much. Later on I added Network Service on the C: drive (Assuming Exchange was installed on this partition). Once I did that I restarted mail submission service and Exchange transport service. That fixed the issue. So I am now actually out of trouble. As my hub transport server is now working fine. Though thanks for your help.
