 Outlook 2007 unable to connect to Exchange 2007
Domain Controller, Exchange 2003, Exchange 2007, Outlook 2007
My environment is 2 DCs (one of them is the GC), new Exchange 2007 server, and an old Exchange 2003 server. For some reason when I am setting up a new account in Outlook 2007 with the new Exchange 2007 server, it says the following error when trying to Check Name. "The action can not be completed. The connection Microsoft exchange is unavailable. Outlook must be online or connected to complete this action. It is working fine if i try to enter in the old exchange server or the GC any suggestions? Thx.

Yes those roles are installed. I checked that DNS is working ok. Also it was never a DC. I am running it on Windows Server 2008 Datacenter without HyperV 64bit version SP 1

Are you able to ping the new Exchange server by IP? By name? Is the machine from which you are trying to connect using an internal DNS server, or an external DNS server?

You should have no problem pinging by IP address. If you cannot ping by name, then the source of DNS should be investigated to determine if it is using internal DNS, which it should be. If it is not using internal DNS, fix that problem and try to ping the Exchange server again. If it is using internal DNS, then check to see that the Exchange server is listed in the local DNS table by the name you are using to connect to it. If it is listed, but the name is not the one you are using,change the name in Outlook. If it is not listed, add it to the DNS entries.
