Exchange 2007 error - 550 5.1.1 RESOLVER.ADR.ExRecipNotFound; not found
We migrated from Win 2003 with Exchange 2003
to SBS 2008 with Exchange 2007.
Now we get this error every time a user sends an email to another user within our domain.
External emails are OK.
Also getting a "connect to sites" prompt asking for a user name and password every time we do anything in outlook (eg start outlook or send email).
My DNS looks like this - have I set it up wrongly?

Whilst my own solutions was the correct answer on this occasion, I suspect that upgrading to SP3 may have also helped.

The "connect to sites" could have been resolved by the SP3 upgrade.
But, I was using Outlook 2007 and before I did the SP3 upgrade, I upgraded outlook on my PC from 2007 to 2010 and I think this seemed to fix the problem.
Actually I didn't really test it much before I also applied the SP3. So who knows? You were probably right anyway.
Anyway. A big thank you for your response.
THANK YOU !
