1. Understanding Client Access Services in Exchange I want to spend some time now going over the concepts of understanding the client access services in Microsoft Exchange. Now, as I told you before, back when Exchange 2007 came out, they had broken Exchange into a bunch of different roles. And then slowly, over the years, […]

1. Understanding Public Folders So what are public folders? All right, so public folders allow our users to easily share and organise information into a folder that can be accessed by the different users in Microsoft Exchange.
