User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36 Steps to reproduce: I receive a message that contains an attachment * .doc Actual results: Attachment appears as text in the message body. There is no possibility saving attachments. Expected results: Attachments should appear in a list at the bottom of the letter. Must be able to save an attachment.

I don't know how this message was generated. It does NOT contain a .doc attachment. The attachment is HTML. Read the message source: ------==--bound.269560.web1g.yandex.ru Content-Disposition: attachment; filename="=?UTF-8?B?0YHQvNC10YLQsC5kb2M=?=" Content-Transfer-Encoding: base64 Content-Type: text/html; name="=?UTF-8?B?0YHQvNC10YLQsC5kb2M=?=" TB displays the HTML as message body, since there is otherwise no message body. There's little we can do about that. The message is in many ways corrupt. Since TB displays the HTML, I copied that into a HTML file, which looks mainly like mojibake (https://en.wikipedia.org/wiki/Mojibake).

However, this investment has the extension * .doc. And this document is opened in Microsoft Word. The main problem is that I can not save it as a file. Any e-mail service (mail.ru, yandex.ru etc.), which has a web interface makes it without problems. I have to use the extension "Show All Body Parts 1.2" to save the attachment. I do not consider the problem solved.

I add. The name of the topic, I did not specify what kind of content is the file actually is. I ask to pay attention only to the file extension * .doch Thanks.

As I said, the message was corrupt. I've manually corrected it, so you now have a plain text part and an attachment. I can't open the attachment, but perhaps you can.

As I said, the message is corrupt. We have no resources to support users who present corrupt messages. Although you may not consider the problem solved, no one will work on it. If you found an add-on that offers a work-around, even better. Please respect the decision to close this bug.

Add-on comment says: You might need this if someone sends you a message with a “hidden” attachment, i.e., a message whose structure is *malformatted* such that Thunderbird is *“correct” not to display it*, but you still need to get access to it.

OK, I base64 decoded the text/html part. This time it looks right. It's not .doc, it's HTML data.

The message attachment contains HTML, not MS Word format. You can just open this with Firefox. MS Word will open it, too ;-)

I understand all that you have written to me. And I understand that the attachment was not formed properly and may not be a man. Still Tunderbird can not gracefully handle this situation. Why can not I save attachments even if I turn off the "Display attachments inline"? Web interfaces provide an opportunity to preserve such an attachment. Okay. It does not matter. I will use the extension. Many thanks.

OK, you can always make software more error tolerant. But we have no resources for that. OK, I'll reopen this with a different summary. Don't expect any action here soon ;-(

There is a hidden preference: mailnews.display.show_all_body_parts_menu Set this to true. Then under View > Message Body as you set "All body parts". That will give you access to all the parts including the attachment you're missing. I think this is graceful enough.
