You haven't mentioned which version of why email client he is using. From reference to PST I assume it's Outlook but the version helps.
If it's a PST file then it has nothing to do with synchronising emails. PST are for emails you've received and moved into an archive. I have a few PST and moving them to a new laptop or if it gets rebuilt is not a problem. In fact moving to Outlook 2007 on Windows 7 from Outlook 2003 on XP, I just copied over the PST files and then opened them. For my live mailbox in Outlook it will have resynchronised.
