Migration Exchange 5.5 to 2003

HI
We have a network with two 2003 servers install with AD, we also have a
exchange 5.5 install in the domain, We install a new exchange 2003 in the
existing exchange 5.5 organization to migrate all mailboxes from the 5.5 to
the 2003 exchange. That part went perfectly. All mailboxes have been migrated
to the exchange 2003.

The problem we are experiencing is that when we create a new user in AD, the
mailbox is created ok and is created in the new Exchange 2003, but that user
cannot receive any emails from the outside world??? all the mailboxes that
have been migrated from the 5.5 to the new exchange 2003 server are able to
receive emails. users new or old are able to send emails in the local lan.

We are wondering do we have to remove the exchange 5.5 to make those user
with new mailboxes able to receive emails and do we have to create a smtp
connector in the exchange 2003 to be able to receive email for these new
users.

I have procedure to remove the last Exchange 5.5 from a organization is
there any docs or info to hepl us out.

Thank you

National

What have you done so far to test that internet mail will not get to your new
users. It sounds like a problem with the recipient policy.
