1 Exchange Server Enterprise 64bit Rollup 8 SP1
2 Windows 2008 R2 Server
3 Exchange Server 2007 Enterprise 64bit SP3 Rollup 10
4 Windows 2003 Server
Just installed 1 & 2 above 3 & 4 are existing on the network
3 receives email internally and externally
On the Exchange 2010 server I moved one email client over today from the 2007 server.
The move was successful
Restart outlook 2010 and the settings reflect the 2010 server name which is great.
My problem is this
Can not send mail or receive mail on the 2010 client.
sent email internally
sent email to external client
from 2007 client sent email to the 2010 client
from external client sent to the 2010 client
None of the above work.
I am trying to coexist with the 2007 server until I get all the client moved to 2010.
I have OWA working on 2010 just internally
Just mail flow not working at this point.
