Mail sitting in E2k3->E2k7 (Routing Group Connctor) Queue?

Mail sitting in E2k3->E2k7 (Routing Group Connctor) Queue?

We have an Exchange 2003 Server that gets the mail from the internet then
passes it along to the users on the Exchange 2007 Server.

Users are complaining that mail is taking 10+ minutes to get from the 
internet.

Looking at the Headers and the Queue on the 2003 server , you can see it 
stuck on the 2003 server.

I've also posted this:
http://forums.microsoft.com/TechNet/showpost.aspx?postid=2531367&siteid=17

I had to set the 2003 SMTP virtual server from 100 to 300 concurrent 
connections, then restart SMTP, No Luck

for recipient policies, I've converted over all my "Address Lists", and my 
"E-mail Address Policies"  to OPATH filters instead of LDAP filters

Under Accepted Domain, I have all of them listed and all set to 
Authoritative, though They were there, I don't remember doing anything to 
them.

 Both my E2k3 and E2k7 server are in the same site, same AD, same subnet, 
same room, though Different Racks... (-;

HELP!  the delay is annoying!

RE: Mail sitting in E2k3->E2k7 (Routing Group Connctor) Queue?

Hello Scott,

Thank you for posting here.

According to your description, I understand that the emails send from 
Exchange 2003 to Exchange 2007 will delay. If I have misunderstood the 
problem, please don't hesitate to let me know.

Based on my research, when you set up a new Exchange 2007 Server and joined 
it into his existing Exchange 2003 Organization, also created a 
bi-direction Routing Group Connector between his Exchange 2003 RG and 
Exchange 2007 RG. Then, you found e-mail from the mailbox in Exchange 2003 
server to the mailbox in Exchange 2007 server will fail or delay.

This issue is caused by the LinkState table in Exchange 2003 which is no 
longer supported in Exchange 2007 and that will cause message routing issue.

I suggest you disable LinkState on all his old Exchange 2003 Server and 
reboot the server. To disable LinkState information:

a) Open a command prompt and navigate to the ..\Exchsrvr\bin directory in 
your Exchange installation directory. By default, this directory is <drive 
letter>:\Program Files\Exchsrvr\bin.
b) Type the following command:

Regsrv32 -u xlsasink.dll

c) Restart the following services:

Microsoft Exchange Routing Engine service (RESvc)
SMTP service (SMTPSVC)
Microsoft Exchange MTA Stacks (MSExchangeMTA)

More Information:
--------------------------
To make the mail flow working between Exchange 2003 and Exchange 2007 
servers in a mixed Org, we need to ensure the following 3 pre-requirements 
done:

1. Create two RGCs (bi-direction) between Exchange 2003 RG and Exchange 
2007 virtual RG by using Exchange System Manager in Exchange 2003 (don't 
recommend do this by using Exchange 2007 Management Shell), and make sure 
select one Exchange 2007 Hub Transport Server as local bridgehead server.

2. Disable LinkState info on all old Exchange 2003 Servers.

3. Ensure the computer account of all old Exchange 2003 servers is 
belonging to the ExchangeLegacyInterop security group under the Microsoft 
Exchange Security Groups OU in ADUC. This is because old Exchange 2003 
servers need appropriate permissions to access Exchange 2007 resource.

Hope this will help you handle such kind of issues in the future. Also I am 
looking forward to more and more knowledge sharing messages regarding 
Exchange 2007 and this will help us get solid on the new product support in 
a short period.

I hope these steps will give you some help. 

Thanks and have a nice day!

Best regards,

Terence Liu(MSFT)
