Exchange 2010/2003 coexist OWA issue
Posted on 2010-09-13
I just installed 2010 Exchange into an existing 2003 forest. I did all the AD, domain, schema prep successfully, installation installled without issue. i can see all the legacy exchange mailboxes just fine in the 2010 emc, but when trying to log into webmail on a legacy 2003 account i get " Your request couldn't be completed because no server with the correct security settings was found to handle the request. If the problem continues, contact your helpdesk" But if i create a new user on 2010 i get in just fine?
