OLE sounds like the easiest option for a script that will run from your computer. You will run into security/logon concerns if you try to put this on a server somewhere.

use Win32::OLE qw(in);

my $Outlook = Win32::OLE->GetObject("Outlook.Application")
 || Win32::OLE->new("Outlook.Application");

my $Session = $Outlook->Session;

for my $Folder (in $Session->Folders) {
    next unless $Folder->{Name} =~ /Personal Folders/;
    for my $SubFolder (in $Folder->Folders) {
        next unless $SubFolder->{Name} =~ /Code Eval/;
        for my $Item (in $SubFolder->Items) {
            print $Item->{Subject} . "\n";
            print $Item->{Body} . "\n\n";
        }
    }
}

This was taken from code I wrote a few years ago. I can't remember if it's important that I used regexps to match folder names instead of string comparisons.

Update: minor code tweaks
