There are several Outlook 2000 on eBay which is around the era Jornada 720 was released.
If you buy the link through this link, HPC:Factor gets a percentage. It's 9.99GBP to 15.00 EUR.
The one sold for 9.99GBP is without serial, so be careful.
Thanks for sharing the URL that got it working with us, I think this is a news for us here at HPC:Factor.
Well, about the screen, it might be good to hard reset, but proceed with caution as Jornada 720 may be showing signs of wear and it may do more harm. There are threads on HPC:Factor forum about replacing the screen. You can search for it, it's easy to find.
