I previously used CodePlex’s Attachment Reminder Add-in for Outlook 2007 which prompts for outgoing emails with "missing" attached files.
But now we have a more "official" version called the "Forgotten Attachment Detector" from Microsoft’s Office Labs.
The "Forgotten Attachment Detector" Add-in for Outlook 2007 checks 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.The "Forgotten Attachment Detector" uses the presence of certain keywords such as “have attached” and “find attached” to determine if a mail is likely to include an attachment. To improve its accuracy FAD also uses a set of secondary keyword pairs. These are words that have a lower likelihood of indicating a mail is likely to include an attachment except when they appear together. For example: Finding just the word “attached” in a mail isn’t a reliable indicator that a mail is likely to include an attachment. You might just be taking about your “attached garage” (it’s unlikely your actually going to be trying to attach a garage to an email now isn’t it?) However, if the word “attached” appears in the same sentence as say the word “file” (as in “I’ve attached the related file”) then we think there is a pretty good likelihood that the mail should include an attachment.
