Don't copy and paste the content of the message or forward the message (the original message is required so the message "headers" can be inspected, which contain important information about the email's origin).


You can attach multiple messages in the new message. Make sure that all the messages are the same type: either phishing messages or junk email messages.

  1. Leave the body of the new message empty.
  2. Use either .msg (default Outlook format) or .eml (default Outlook on the Web format) formats for the attached messages.
  3. When you're finished, click Send.
