What's The Diffrence Between Microsoft Out Look & Out Look Express?

Both are email programs provided by Microsoft and both  have different versions but Outlook Express is the 'light' version that is usually free whereas Microsoft Outlook is the commercially available version that costs money.

Having just switched from express to outlook proper, my view on the relative use of them is mixed. Outlook has many more features - a calendar, tasks and other features whereas Express is more basic. However, Express is much easier to use when doing stuff like using signatures (total nightmare to set up in Outlook 2003!). On the other hand setting up new email accounts and testing the settings is a doddle in Outlook and a pain in Express.

My advice would be to try before you  buy...
