Imani T.Dec 30, 2025The answer is B. Outlook 2010 has a built-in attachment blocking feature that flags certain file types as potentially unsafe, and executable files like .exe are on that blocked list by default. When you saw that warning about an unsafe attachment and clicked Yes anyway, Outlook still sent the email, but the recipient's Outlook client blocked the .exe on the receiving end because of its own security settings. The warning you got was Outlook's way of telling you exactly what was about to happen, and the outcome confirmed it. The other options do not fit because a wrong email address would result in a delivery failure or bounce, not a successful delivery where the recipient just cannot open the file, and HTML format has nothing to do with attachment blocking.
Dragomir B.Dec 23, 2025B, obviously. That warning is Outlook's Level 1 attachment block talking, not some mystery.
Luis F.Dec 12, 2025Saw almost this exact scenario on my exam last month and I almost went with C because I figured maybe his Outlook was outdated, but then I remembered that Outlook 2010 has a built-in attachment blocker that flat out blocks .exe files on the receiving end even if the sender gets through with just a warning. B is your answer, the recipient's Outlook silently blocked it because .exe is on the unsafe attachment list by default.
Nina C.Dec 13, 2025Right, and the part that helped it click for me is that the sender's side only throws a warning because sending is not the same as executing, but Outlook classifies .exe as a Level 1 restricted file type on the receiving end, so the recipient never even gets a chance to open it.
Grace U.Jan 5, 2026Older Outlook cannot open attachments sent from a newer version, so C.
Luis F.Jan 8, 2026Hey Grace, totally see where you're coming from but the version difference actually affects how the message body renders, not the attachments themselves, which points to B. Attachments are handled separately from the message format, so older Outlook can still open them fine.
Nina C.Dec 18, 2025Pretty sure it is C, older Outlook just cannot open that.
Dragomir B.Dec 19, 2025Nina, appreciate the input but you need the question in front of me to get a useful correction here, and you did not paste it. Drop the full question text and I will tell you exactly why B is correct.
