I use Thunderbird version 31.5.0 Incoming email attachments and also some computer, windows 7, files come in an encoded form. A support popup asks to select the appropriate service and language to be able to read the message. None of these selections enable the message or file to be read. This question comes from a home user of basic knowledge of computer operation.

What do you call encoded format? All attachments are encoded, but it sounds like yours are not in the format you want.

A common problem people have when receiving mail from people using Microsoft Outlook is getting attachments called winmail.dat see https://support.mozilla.org/en-US/kb/what-winmaildat-attachment

Matt, thank you for the reply. Downloaded winmaildat - attachment, no improvement. fault occurs on receipt of a pdf file attachment In Mozilla Thunderbird. When opening I am faced with a pop up which says, 'Select the encoding that makes your document readable' choices being, Windows (default) MS - Dos Other encoding. Each selection as is the initial opening, just a mess of figures and letters!1 Regards, Gerrard.

Now that is a new error message. Do you get the same result if you save the attachment to your desktop and then open it?
