I have a user who's been migrated to a new machine. Her old one was a Dell GX270 with about 256MB RAM and XP SP2 and Outlook 2003. The new HP has the same software, but has 2GB RAM and is a new dual-core job.

The user has 563 PSTs. I wish I were exagerrating. She literally has some of these with 1 email in them. She has all of them "opened" in outlook (By that I mean she has them loaded, but not all are expanded). And... surprise, surprise, she's getting a lot of corruption in the PSTs, giving her problems opening emails and personal folders constantly.

Here's the kicker: The original machine runs them just fine. It's old and slow, but it chugs along and doesn't seem plagued with this issue. She has all of the files open in the same manner, and works.

Intensely frustrating, let me tell you. She refuses to believe that having 563 PSTs open is a bad thing because they work on the old machine.

So, has anyone ever seen anything of this caliber? Any suggestions? The obvious one of "Close them" isn't an option at this time, and merging them down isn't either. This user claims not to have time, and keeps referring back to the old machine where her setup has worked for 3 years.
