Hi Experts,

This is probably a silly question for you folks, but can you please explain from your own words what are the 4 main differences between Exchange 2007 and  Exchange 2010.

In addition to that, can you please provide a quick chart or comparison between both versions?

Thanks in advance

    The major reason I have been deploying Exchange 2010 is high availability with just two servers, using standard edition of Exchange - it would take four servers with Enterprise edition of Exchange on 2007.
    The other major advantage is I/O improvements, allowing a lot more users per mailbox server, 1000 users is easily achievable with Exchange 2010.

    Everythign else is really features and benefits from an admin point of view. Looking at the costs of the product, the reduction in server count and the HA are the major selling points.
