Hello, I have a super-massive Outlook.pst file (~3GB), and a similarly massive archive.pst file (~2GB). I will soon be bringing up a new machine (Win7 Pro), and I want to import these 2003SP3 files into a later version of Outlook. I am attracted to the 2007/2010 version. This is because I'm seeing comments in other forums and reviews that Office has been going downhill since then, and that it now can be a big hassle just getting it installed. I would also be open to alternative email applications, if there are any that can import massive, old pst files. I would be grateful for comments, suggestions, and/or advice from users more expert than me. Thanks, Ed
