Don’t you just hate it when you forget to attach something you said was attached?
In this case the email, from my work account using Outlook, included the words “happy to provide the attached PDF version“. Would it be so hard for Microsoft to include a little tool that detects the words “attachment”, “attached”, etc… and, where a sent item includes that word but no attachment, gives you a little warning.
Maybe they’ve done it already and I’m behind the times…Gmail did it two years ago:
