MS Exchange/Outlook getting the following error when sending emails: "a program is automatically trying to send an email on your behalf, do you want to allow this

From Support

If you have a question or seek clarification, please call Technical Support.

Problem:

Apparently this problem can happen if the user is running MS Exchange and Outlook 98 or Outlook 2000 with the security updates.

To prevent worm viruses, such as the ILOVEYOU virus, from quickly spreading, Microsoft has restricted features that can potentially be used to write virus in Outlook.

Solution:

Start Outlook Express and then select "Tools/Options/Security". Then uncheck "Warn me when other applications try to send mail as me."
