Outlook Alternatives

Okay, here’s another groupmind query: does anyone know of a good application that would serve as an alternative to Microsoft Outlook? (Note: not to Outlook Express, which is just for email, but to Outlook, which has scheduling functions.) But here’s the catch: I also want this program to be able to sync up with my Pocket PC as well, as Outlook does. I’ve found programs that will replace my Pocket PC calendar program, and I have found things to replace Outlook, but nothing that will do what I want: sync my Pocket PC’s and my desktop PC’s scheduling information. (The email aspect of Outlook is irrelevant to me, so that doesn’t factor into this.)
