Outlook

Depends on where it was installed.

Look for any file maked *.PST.

well, it depends on if you're using outlook, or if you're using outlook express.

outlook uses .pst files if you have it configured to do so. outlook express stores it in some goofy location under your profile. i don't remember the exact location but you can find it under tools->options->storage?

If you using XP it's C:\Documents and Settings\User name \Local Settings\Application Data\Microsoft\Outlook\ .PST

Search file with extention: *.pst
Usually c:\documents and settings\yourname\local settings\application data\microsoft\outlook

I noticed you're an IT manager, so I'm guessing you're using exchange.
I will also bet users have the mail available for offline use.
Then actually you want the ost file.
The .pst file is the personal file and not the default delivery location.
So, look again under
C:\Documents and Settings\USERNAME\Local Settings\Application Data\Microsoft\Outlook
for the "outlook.ost" file.
