I'm having an issue with co-existance. My test user is having no issues with emailing from 2010 Exchange to 2003. When i'm trying to respond to that user from my 03 inbox my msg doesn't get delivered into 2010 test inbox. I ran msg tracking on my exchange 2003 and msg gets as far as being passed over to one of the HT servers.
I'm not sure what i'm doing wrong.

Don't know it this is your problem: By default Exchange Server 2003 is authoritative for every SMTP Address space in the Recipient Policies where the Checkbox "This Exchange Organization is responsible for all mail delivery to this address" is activated.
If so, you will need to unselect this checkbox.

Thanks for you help. I took your advice, but still weren't able to receive emails.
After some pocking around i increased the size of my test DB and Log particions. Now the messages are flowing.
