Last week, we had create New Send Connector so that all outboud mail will thorugh Exchange Hub Transport not Exchange 2003.

We should like to start MSExchange services before running demotion.Please help

The event IDs are very generic ones. Run Exbpa and see what exactly that comes up with. Also incresed the diagnostics loggin on the exchange 2003 server on AD and MTA components and then try to start the services.Also try to shut down the E2k3 box, reboot the GC in the AD site and then reboot the E2K3 again and see if that makes any difference.Raj

Actually we have 5 GCs in AD Site with Exchange 2003, 3 of them running on Windows Server 2008 while the rest running on Windows Server 2003. I restarted the GCs (Win2k3) due to its appear in Exchange 2003's DSAccess tab Please advice

run a DCDIAG and NETDIAG from the exchange and see the report.Looks like some issue with AD.Raj

I read an article saying that there was an issue if deleted default email policy due to Exchange 2003 using SMTP and X400 while Exchange 2007 only using SMTP to send an emails. Previously, there was an issue related to email policy in this coexistance enviroment. So, we decided to delete the default email policy and then recreate it using EMC(Exchange 2007). At that time, this problem not occur due we are not shutdown the Exchange 2003 server.I forgot the link of that article but could you provide me the instruction how to add back X400 address to recreated default email policy. This may help tp solve the problem.Thank

HiSure you are right, the issue maybe caused by the default Email Address Policy (EAP, a.k.a. recipient policy) has been modified or missed the X400 address type and the policy order was changed.You could solved it by 1. Added the X400 address type back to the default EAP. 2. Set the policy order of default EAP to 2147483647 (lowest).The detail procedures:1. Install Windows 2003 Support Tools from your Windows 2003 CD in case you haven't installed it. 2. Click Start->Run, type "adsiedit.msc" without quotes and then click OK. 3. Browse to the following location:CN=Default Policy,CN=Recipient Policies,CN=Headquarters,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=paclib,DC=com4. Right-click CN=Default Policy and then click Properties. 5. Locate the msExchPolicyOrder attribute and set the value to 2147483647.6. Locate the gatewayProxy attribute and add the following entry:X400:c=US;a= ;p=YOURHeadquarters;o=Exchange;7. Click OK. Regards!gavin
