Most of your email will migrate over anyway if you are on a network and your email messaging is Exchange.
So might be best to setup and configuration your new PC first and then check to see what didnot come over before import the pst file
One way to do this is to creat a folder. Name it email info for example.
Then go into Outlook, select Import/Export
Export to a file, Personal folder file (.pst)
Include subfolder, Point to the folder named "email info" (get the pst file a name you will remember)
No encrption, No password
The file size could 20-300MB and up. So you will need a CD ROM or DVD to copy this file.
After copying these file to the media of your choose then Import the data to the new PC by using Outlook Import.
