Outlook

Although often used mainly as an e-mail application, it also provides calendar, task and contact management.

It can be used as a stand-alone application, but can also operate in conjunction with Microsoft Exchange Server[?] to provide enhanced functions for multiple users in an organisation, such as shared mailboxes and calendars and meeting time allocation.

Versions for Microsoft Windows include:

• Outlook 95
• Outlook 97
• Outlook 2000, also known as Outlook 9
• Outlook XP, also known as Outlook 10

One of Microsoft's goals is for the email client to be easy to use. Unfortunately, the embedded automation features and the disregard of security features (which would inconvenience a non-sophisticated user), were exploited by numerous people leading to the phenomenon of email viruses, typically an email attachment executing on the user machine, replicating itself via mass-mailing to the machine address list.

Microsoft took some corrective steps, and the latest versions of Outlook suffer much less from this problem.
