Try importing into Live Mail (I think that’s what it’s called) or maybe Thunderbird.
I have gone through the pain of trying to train someone multiple times who kept gigabytes of message traffic and never got rid of anything. That person is learning Gmail.
My wife went through similar with going to 7 from XP and finding out that the Earthlink client didn’t work in 7. VirtualBox saved the day there.
I am done with standalone clients.

Thunderbird is much better anyway... you’ll need to locate your .pst file on the old drive...
