How can I archive old emails using Outlook 2007 and 2003

I am trying to prepare documentation for our users to they can easily Archive old emails and view them from a PST when needed. I recall years ago having to manually move emails I wanted archived to a seperate folder and manually exporting that folder to a PST, then importing them back in to another folder and going back and deleting the originals. I know it is easier then that now or even a few years ago. I have Outlook 2007 and see an option to Archive. I go through the procedure to Archive my entire mailbox from all items earlier then say 04/23/2013. I see where it creates a PST file on the share I point to, but how to I bring it back in so it is convient to see? Will it be mixed in with my normal mailbox or do I need to go down to an archive folder to see older emails? All advice welcome. I know I can manually make this happen for users but I know there is an easier way then what I am doing. I basically want all emails older then a certain date to be stored in a PST file on a file server, but am hoping it is convient for them to view if needed. All advice welcome and if anyone has info on Outlook 2003 I need to write up a procedure for that also. We have Exchange 2007
