Email migration from SBS 2003/EX03 to Server 2008/Ex20 and OWA
Posted on 2011-03-18
this weekend I plan on migrating mailboxes from EX03 to EX10.
I know that internal users will be able to access their email from within Outlook, whether the mailbox still resides on the EX03 server or has been moved to the EX10 server (because Exchange intelligently notifies the Outlook client of URL to the EX10 server).
But, what about external access to the mailboxes via OWA ?
While I am migrating mailboxes, will I need to provide two URLS....one URL that maps to the Ex03 server and one that maps to the EX10 server?
