What are the differences between Microsoft Outlook Express and Microsoft Outlook ?
Microsoft decided to give these two programs very similar names, for they have a very important common purpose: receive, write and send mails. But as you can guess from the very difference between the two names, Express is a light version of Outlook and can manage only mail, whereas Outlook has a whole set of extra functions not directly related to mails, and is part of the Microsoft Office package. Their files are different, and Express Archiver reads only Outlook Express.
