I recently switch from Outlook to Windows Live Mail. Using multiple computers I find several advantages to using a web based product. When I add an appointment to my calendar or a new client contact using my primary desk computer, it’s live and ready when I access my account from my laptop or smartphone. I was able to sync Outlook between computers but my program I used had to be updated manually. So far so good!
Windows Live Essentials includes email, calendar, writer (which I used to write this post), along with a few other bells and whistles. I was surprised at how similar Outlook and Windows Live are in regards to contacts and organizing your contacts into categories. So far so good!
