Quick Outlook question

[Curio]

Does the autoarchive feature in Outlook '07 backup everything - or does it just move files of a certain age?

Basically, I want my machine to automatically backup all my Outlook e-mails, every night, onto a USB flash drive....without any prompting. What's the best way to do this?

Hmm it depends how you're saving them now, if you have a POP3 account then it's probably downloading to PST file locally on the machine, if you back this file up to your USB hard drive it would be a backup of all your email.

Is there a way I can make Windows 7 to this automatically for me - so I don't forget?
