The Forgotten Attachment Detector (FAD) for Microsoft Outlook is a Grassroots Project from Bhavesh Chauhan, who works in Hyderabad, India, as a Software Development Engineer for Microsoft’s IT team.

When you send an email FAD checks it for keywords that indicate you’ve forgotten to attach an attachment. If it detects this, it notifies you and gives you a chance to correct any mistakes.

There is one more!

Missing Attachment Powertoy integrates with Microsoft Outlook and scans each message before it is sent, looking for words or phrases that would normally indicate an attachment. If it finds such references but the message does not have an attachment, it brings up a dialog to alert you and gives you the option to revise the message before sending. You can customize the list of trigger words based on your personal email habits and words that you would commonly use when sending a file attachment.
