Exchange 2010: OWA versus OWA light
Last week I got a question from one of my colleagues to see if there was a list available somewhere that describes the differences between Outlook Web App and Outlook Web App Light, as there is a list available describing the differences between OWA Premium and OWA Light in Exchange 2007 (Exchange 2007 = Client Features in Outlook Web Access).
The following link was easily retrieved: Supported E-Mail Programs and Features, which includes a table listing some of the differences when accessing your mailbox using OWA, OWA Light, Outlook, Entourage, Mobile Device, POP, IMAP.
A great article about using OWA Light 2007 can be found here:
Microsoft Outlook Web Access Light 2007
But not really an overview of comparing OWA, to its light version in Exchange 2010.
