Current Environment - Windows 2003 Forest & Domain Functional Level and Exchange 2003
Still one or two customers on NT4 Domains connected via Trust Relationship to above environment.
XP clients in NT4 Domain use Outlook 2003 to connect to Exchange 2003 organistation.
We plan to introduce additional Exchange servers probably Exchange 2007 servers co-existing with Exchange 2003.
My question is: Will the XP clients in the NT4 Domain still be able to retrieve email after the schema upgrade that will allow us to introduce Exchange 2007 servers and if so can the mailboxes for NT4 users be hosted on the Exchange 2007 servers or will these have to be on the Exchnage 2003 servers?
Thanks for any advice in advance
P.S. I know we should be decommissioning the (unsupported NT4 domain) and this will be the case soon however there is a need to introduce additional Exchange servers first
