Attachments with underscore

If I receive any Excel or Word document with an underscore in the name, Thunderbird will not open it. I have checked this by the saving the documents in question, removing any underscore and then sending it to myself. It opens fine. I use LibreOffice for all MS related documents. This has nothing to do with the addition of an underscore that some people have pointed out. I am using Thunderbird on 2 different Linux computers and they both behave the same way. The computer I am currently on is using Thunderbird 91.6.2.

BTW, the saved, underscored document opens fine from the file manager (Nautilus, as I'm using Gnome).

Actually, I just had this happen again, but with a "normal" attachment. Is it possible that Thunderbird is not allowing me to open attachments from certain senders? Cause it's the same sender in both cases.

It "might" be that the sender is using some obsolete or non standards compliant mail product.

When viewing one of the emails open the message source (ctrl+U) Scroll down (it will probably be a long way) until you find the attachment definition. It will look something like this

Content-Type: application/x-zip-compressed;  name="emails.zip"
Content-Transfer-Encoding: base64 Content-Disposition: attachment; 
filename="emails.zip"

How is the attachment you are having issues with described?
