Hi,
We have W2002 forest and Exc5.5 server.
First we installed new W2003 child domain. And We tried to install
Exc2003 in the same site an organization as Exc5.5. We completed
Exc2003 installation. Also we installed ADC and it works , because
when we create a user mailbox in new W2003 it is replicated to Exc5.5
Directory.
So When we send e-mail from Exc2003 to Exc5.5 it waits in the queue of
EXC5.5 X400 ExchangeMTA. At the same time when we send e-mail from
Exchange5.5
to Exc2003, we receive an undeliverable message as soon as sending.
How can I solve this. Is this a problem with Exchange2003 installation?
Tunca.
