I tried OsaSync years ago and it didn’t work very well, duplicating items and the like. I think I’ll wait to hear from someone who has actually tried the latest version before jumping on board again!

Or you could use a free service such as Microsoft Office Live, which provides a free e-mail account and includes an Outlook connector that provide free syncing of E-mail, contacts, calendars, tasks and notes.

From the http://SmallBusiness.OfficeLive.com site:

“Can I use Microsoft Office Outlook to manage e-mail, calendar, contacts, and tasks?

Yes, the Microsoft Office Outlook Connector enables two-way synchronization of e-mail messages, calendar items (available when you purchase the Premium E-mail service), contacts, tasks, and notes between Outlook and Office Live Small business Mail.
