RE: Two questions - Exchange 2003 2010
Unfortunately there seems to be some other issue. We simply can't get mail flowing from EXCH2003 to EXCH2010. It's obviously some sort of communication issue since the Public Folders aren't replicating either. The various settings in the default receive connector look correct. I've verified that port 25 on EXCH2010 is open to EXCH2003, but still no go. I've read some good documents on the various post-installations steps that should be performed and we've completed all of them. We may redo our test installation and see if we have better results.

We can send from 2010 to 2003 and from 2010 to Internet addresses (i.e. non acadiau.ca addresses) but we're unable to send from Exchange 2003 to Exchange 2010 and from Exchange 2010 to other non-Exchange addresses within our domain (i.e. acadiau.ca addresses on other servers). Exchange 2010 appears to be trying to deliver them locally. Any pointers? Everything appears to be configured properly but obviously we've missed something. Also - our Exchange 2003 server occasionally gets tied up trying to deliver messages to domains that are registered but their DNS servers aren't answering to accept email (1800thriller.com just this afternoon for example). Our Exchange 2003 server is configured to send through a Postfix server before going on to the Internet. Our Postfix server is sending the message back to Exchange with a 450 error. Exchange retries 1 minute later. And as is configured, this continues for 2 days until Exchange gives up (or if we delete before then). This isn't usually a problem unless 3 or 4 outgoing emails get in this state at the same time then all outgoing email comes to a halt. I previously read about this issue and the fix I found mentions to not make the change unless Microsoft Support Services advises (the only URL I can find this aft is http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_24771370.html. it references Exchange 2007 but it's the same sort of thing for 2003) We've been addressing this issue as it arises and we're hoping it'll disappear once we migrate to 2010.

RE: Two questions - Exchange 2003 2010
I thought I would add a bit more info to Tammy's first question. Our two test servers are called EXCH2003 and EXCH2010. After the 2010 installation, two connectors were created and appear when using Exchange System Manager. In the First Routing Group (associated with EXCH2003), the new routing connector was called EXCH2003-EXCH2010. In the Exchange Routing Group (created by the 2010 install), another connector was created called EXCH2010-EXCH2003. These connectors cannot be modified with Exchange System Manager (complains that version 8 is required). Our understanding is that the first connector controls mail going from EXCH2003 to EXCH2010, while the second one controls mail from EXCH2010 to EXCH2003. They appear to configured properly, but obviously something isn't quite right. Email works from mailboxes on EXCH2003 to mailboxes on EXCH2003, from EXCH2010 to EXCH2010, and EXCH2010 to EXCH2003. However, EXCH2003 to EXCH2010 does not work, so our guess is that the EXCH2003-EXCH2010 connector is the one that is not working properly. If anyone has any suggestions on what to look for we would really appreciate it. We don't want to proceed with the production upgrade until we get all the details working in our test environment.

We presently have a test environment setup. Our 2003 test server is unable to send to our 2010 server. We can send from 2010 to 2003 and from 2010 to Internet addresses (i.e. non acadiau.ca addresses) but we're unable to send from Exchange 2003 to Exchange 2010 and from Exchange 2010 to other non-Exchange addresses within our domain (i.e. acadiau.ca addresses on other servers). Exchange 2010 appears to be trying to deliver them locally. Any pointers? Everything appears to be configured properly but obviously we've missed something. Also - our Exchange 2003 server occasionally gets tied up trying to deliver messages to domains that are registered but their DNS servers aren't answering to accept email (1800thriller.com just this afternoon for example). Our Exchange 2003 server is configured to send through a Postfix server before going on to the Internet. Our Postfix server is sending the message back to Exchange with a 450 error. Exchange retries 1 minute later. And as is configured, this continues for 2 days until Exchange gives up (or if we delete before then). This isn't usually a problem unless 3 or 4 outgoing emails get in this state at the same time then all outgoing email comes to a halt. I previously read about this issue and the fix I found mentions to not make the change unless Microsoft Support Services advises (the only URL I can find this aft is http://www.experts-exchange.com/Software/Server_Software/Email_Servers/Exchange/Q_24771370.html. it references Exchange 2007 but it's the same sort of thing for 2003) We've been addressing this issue as it arises and we're hoping it'll disappear once we migrate to 2010. I was hoping someone on this list might know the answer to that for sure.

RE: Two questions - Exchange 2003 2010
That's why I suggested you execute this command, and examine all the information output from it: get-routinggroupconnector | fl This is a PowerShell command, you'll execute it from the Exchange Management Shell on the 2010 server. You might want to do the same thing with get-receiveconnector | fl and get-sendconnector | fl. While there are another potential knobs and switches involved, with the output from those 3 commands we will likely be able to identify any culprit or provide an additional lead to continue the investigation.

Our two test servers are called EXCH2003 and EXCH2010. After the 2010 installation, two connectors were created and appear when using Exchange System Manager. In the First Routing Group (associated with EXCH2003), the new routing connector was called EXCH2003-EXCH2010. In the Exchange Routing Group (created by the 2010 install), another connector was created called EXCH2010-EXCH2003. These connectors cannot be modified with Exchange System Manager (complains that version 8 is required). Our understanding is that the first connector controls mail going from EXCH2003 to EXCH2010, while the second one controls mail from EXCH2010 to EXCH2003. They appear to configured properly, but obviously something isn't quite right. Email works from mailboxes on EXCH2003 to mailboxes on EXCH2003, from EXCH2010 to EXCH2010, and EXCH2010 to EXCH2003. However, EXCH2003 to EXCH2010 does not work, so our guess is that the EXCH2003-EXCH2010 connector is the one that is not working properly. If anyone has any suggestions on what to look for we would really appreciate it. We don't want to proceed with the production upgrade until we get all the details working in our test environment.

RE: Two questions - Exchange 2003 2010
I spoke too soon. The change allowed a manual telnet session to work, but mail initiated from Outlook still gets hung up. Does Exchange use standard SMTP/port 25 protocol for inter-Exchange email transfers, or does it use something different?

The Get-receiveconnector has so much information it's not entirely easy to decipher, this being our first Exchange 2010 server. I think I have narrowed down the problem though.

RE: Two questions - Exchange 2003 2010
Well, you've identified the problem. You shouldn't have disabled the default receive connector. If you take a look at it, you'll see on the Permission Groups tab, that Legacy Exchange Servers is one of the options. Exchange servers speak to each other using a number of extensions to the SMTP protocol. Those extensions are only allowed when you enable the permissions. The default receive connector allows those permissions from Exchange servers (2007/2010) and legacy Exchange servers (2003). However, the Internet receive connector should only enable anonymous. Generally speaking, most people just enable the anonymous permissions on the default receive connector so they can get by with a single connector. And to answer your other question - Outlook and Exchange preferentially communicate using MAPI, not SMTP. Regards, Michael B.
