iam performing the installation of a new exchange server 2010.THe infrastructure was previously having exchange 2003 with domain on 2003 ser
ver,we migrated the domain to a new machine with 2008 r2 and we proceeded the installation of exchange 2010.Now the exchange installation has finished with co existance to the exchange 2003 and am able to move mailboxes also from exchange 2003 to 2010. i m also able to send mails from internet to the
mail boxes on the exchange 2010 and also can send mails from the users who are still on exchange server 2003.The point where iam really stuck is no mails are going out from the exchange server 2010 either to outside or neither to mailboxes on the exchange server 2003.
what could be wrong with this and wats the possible sol for this .do i need to create internal connector which will use exchange 2003 as smarthost ??
but i tried all this possiblities stll mails are going in the queue on the 2010 machine
need help please
