In Exchange 2003, IT managers often archived older e-mails as PST files on network shares. Aside from being slow and inefficient, it was tedious to keep track of everybody’s archived files and to make sure that users were not archiving to their local hard disk drives.

Exchange 2010 and 2013 allows for archived E-Mails to be stored on the Exchange server. You can create an Archive Mailbox and retention policy with just a few click of the mouse.

Importing PST files can be done using the Outlook client, but this has several drawbacks. The biggest drawback is that you have to log in to each user’s computer, open Outlook and then begin a process that can take a very long time.

Using PowerShell is fast & furious and allows for centralized management of the importation job.

To begin, place your PST files in a shared folder that is accessible from your Exchange server. Open Exchange PowerShell and execute the following commands:

New-ManagementRoleAssignment –role “Mailbox Import Export” –user username

This assigns the necessary role to the users that will import the PSt file. Exit and re-open PowerShell when finished.
