Reproducible: Always Steps to Reproduce: 1. Create and send a message to yourself. 2. Create and send a second message to yourself containing the first one as an attachment. 3. Create and send a third message to yourself containing the second one as an attachment. 4. Open the received message. Actual Results: You will see 2 attached messages in the attachment panel of the third message Expected Results: I was expecting to see only the second message (the second one) in the attachment panel of the third message. I was expecting to only see the first message if I opened the second message from the attachment panel of the third message. Another thing is that when you open any of the attached messages you continue to see both 2 messages in the attachment panel of each message's window but you cannot open any from there. Only from the main message (the third) window are you able to open the other messages. Microsoft Outlook and Outlook Express don't work this way. If you have an email containing several messages each one with its attachments then the attachments panel will be a mess and it will be difficult to know which attachment belongs to which message.
