So, I recently got my HP Jornada 540 to work with a computer running windows XP. The only trouble I'm having with the sync is the e-mail. The only thing I can set up in outlook is a Microsoft Mail account. Which asks for a post-office and such. For me under the services tab, I cannot find the internet mail option, just other stuff that I really don't know how to use. I'm wondering if there is some sort of update I need to preform on the program that will give it the service. As of now, I'm going to attempt to use Outlook Express to Sync to it for e-mail.
