No ... depends how the mail flow works anyways if both these servers are in the same Exchange forest they should be able to work with a RGC created between them which will take care of the mailflow as of now<br />

Hi there, <br />
I have start to migrate exchange 2003 to 2010 (Add one server with exchange 2010)<br />
During the installation, I have defined unflow mail.<br />
Does it mean that if I create one new user (peter) on the new exchanger server 2010, the exchange 2003 server follow &nbsp;the incoming mail (from external organization and internal) for peter to peter ? And peter can send me to user who are on exchange 2003 server?<br />
Thanks,<br />
Regards,<br />
