I downloaded the Outlook backup tool plugin which looks like it will just
copy the .pst file after you exit it. This is simple, but does what I want.

But can I automatically schedule this backup? It has a reminder for me to
do so, but it looks like it's just a reminder, and I have to do a
file->backup to execute this.

Can I have it automatically save the backup file every X days? If so, how?

thanks,

Perry
