I have built a 2010 Exchange Server (VM) Server 2008 64bit. I chose a typical install to keep it simple for the time being.
I have followed an instruction I found after a heap of research off the net: http://www.simple-talk.com/content/print.aspx?article=882
Anyway, all has gone rather well, I have totally snapshotted both servers, taken BUEX Sys Recovery images of my DC and 2003 Exchange server,a full backup of the mail database to tape and disk just in case I have to reverse anything.
I have moved a test user to Exchange 2010. I have tried emailing myself (internally) from the test user using Outlook 2007. I get nothing. Likewise if I do it from myself (internally) to Test User. If I send a mail to my external email account from test user, I get it and likewise when replying.
Now I read that Exchange 2010 creates a Routing Group Connector when installing in a 2003 environment. We run two domains here. One called domain1.com and the other domain2.com This is where I think it has broken down. I could be wrong but I am thinking that since it has seen two different domains, it has not created a routing group.
I have sort of confirmed my suspicions by opening up Exchange management shell and typing:
VERBOSE: Connecting to MX01.domain1.com
VERBOSE: Connected toMX01.domain1.com
Connector | fl
Low and behold, nothing is returned.
Now I have read that I can run New-RoutingGroupConnector but now I think I am wandering into dangerous territory and starting to mess with stuff that could leave me red faced and restoring mailboxes and DC's like crazy.
My question is, am I on the right track or have I missed something blatantly obvious upon installing Exchange 2010 or configuring it via the Console afterward.
I didn't choose custom installation as I wanted to keep it simple as written above. Should I have since it is not a straight forward install as it needs to co-exist with 2003 until I hit the delete button on the VM once I am done with it?
Also you should know that we don't run ISA here, we just have a Cyberguard firewall. Therefore, I created a definition to the new server and changed the firewall rule from our existing 2003 server to the 2010 server to see if mail flowed. It didn't... Not even to the account that was moved to the 2010 server.
A bit more info, is we use our ISP as a mail relay, so we just have our ISP send all 25 traffic to our IP, then within the firewall we tell it to on-send any 25 traffic to our internal IP
Also our domain functional and forest functional level was at Windows 2000! However exchange 2010 still installed. I have now brought both functional levels up to 2008, however this has made no difference.
Do I need to reinstall exchange because of this or am I missing something so very obvious?
Any help would be greatly appreciated
