What Is Same Between Exchange Server 2003/2007 And Exchange Server 2010?
Answer»
Core Infrastructure of Exchange Server 2003 or 2007 versus Exchange server 2010 in same, Microsoft continued to use the JET EDB database as the main database ENGINE
Exchange 2010 still use the concept of mailbox servers to hold US the user mailboxes and public folders
Users can access their email using Outlook, OWA and Active Sync Clients
Exchange 2010 uses the VSS API to freeze the exchange database to perform a backup of exchange server database.
Even if transition of mailbox from exchange server 20032007 occurs, older CLIENT access emails using outlook or OWA won't FEEL much difference on their client perspective, there is no compulsion of upgrading to Exchange 2010.
Exchange Server 2007 5 roles architecture is not changed in Exchange Server 2010. But the MAPI endpoint on Mail Server role is moved to client access server role, where in Exchange Server 2010, All the Exchange Server clients will connect CAS to access the mailbox and the public folders access will be directly threw or to Mailbox Database.
