Starting with Exchange 2010, a new personal storage concept was introduced, called an archive mailbox. The idea is that you can give one or more users a secondary mailbox that can be accessed from anywhere, just like their regular mailbox, and it can be used to store older mailbox data, eliminating the need for a PST file.

In this chapter, we'll look at how you can manage archive mailboxes for your users through the Exchange Management Shell.

cmdlet, as shown in the following example:
Enable-Mailbox –Identity administrator -Archive
