exchange not connecting after sbs 2003 to 2008 migration

Recently performed a migration from sbs 2003 to sbs 2008. very simple migration, no sql or fancy programs to worry about. just the domain, exchange and a few files. i followed all the steps outlined in http://technet.microsoft.com/en-us/library/cc546034(WS.10).aspx to perform the migration. all seemed to go well until i turned the old server off....
it turns out that unless the old server is on, clinent machines cannot send or recieve emails.
all transport roles are setup correct from what i can see in the sbs 2008 box. and all email traffic is directed to the new sbs box via the router.
if i turn off the old server, cannot send or recieve anything, can connect to mailbox. but no transport.
any ideas?

if the router was correctly redirected to the new SBS 2008 box, it should be accepting emails and receiving them, if the migration was done correctly..

However, since you only receive emails if the old box is on, suggests that the router is still pointing to that IP address..

Try changing the static IP of the SBS 2008 server with the static IP of the old SBS2003 box.

router is definately pointing to the correct IP address. all outlook clients are pointing to the 2008 data store. have done several of these in the past with no trouble...

have you checked the DNS settings then?

Tested the SMTP with telnet from the outside?
That should tell you what service your connecting too..
