hi - I have a question here about exchange server 2010, it is in a test environment.
server1: windows server 2003 standard SP2, exchange server standard 2003 SP2. it is a DC with a mail server on it. for sure also with dns, dhcp and wins. mail flow is fine with internal and external.
I would like to replace this server with 2008R2 and exchange 2010. so
I install a 2008R2 server, join the domain, make it a DC. then dcpromo it to a DC. then demote the server1 to a regular server. on the new DC( server2), I raise the function level of domain and forest to 2008R2. and also move the dns and dhcp to server2. at this moment, everything is still fine: internet access, user login, mail flow...
then on server2, i installed exchange 2010. I can move mailbox from server1 to server2. I can see both servers in exchange system manager.
for these mailbox still in server1, I can access them either from http://server1/exchange
or from outlook 2003.
but i can not access these mailbox in server2 through https://server2/owa
or outlook 2003.
I tried these moved mailbox or new created mailbox, neither doesnot work.
on the OWA, it says 'The user name or password you entered isn't correct. Try entering it again.'
on the outlook, it says 'unable to open your default email folders. The microsoft exchange server computer is not available. either there are network problems or the microsoft exchanger server computer is down for maintenance'
the exchange 2010 installation seems a straight through. i do not know why it does not let me access the mailbox, anyone can help?
