I have been tasked to setup up a new Mac for a local company.  They have a slow old PC running Office 2003.  The total personal folders export as a 4.7Gb .pst file but when dropped onto an external hard disk with 50Gb space I get a message saying the disk is full.  I solved this by exporting each folder in the emails one at a time.  These imported into the Mac which is running iMap email (the PC ran POP3 email), but came in as a new folder "on my computer" and did not merge into the existing email folders as I normally expect when going from PC to PC. My question is why when I imported contacts.pst does it create a folder which is empty when the file size of the contacts pst is 1.7Gb?  Any help would be greatly appreciated.  I did advise them not to buy a Mac but they insisted.

Do I have to import the .pst into a newer copy of Office and re-export to get it to work maybe?
