My sister uses Microsoft Outlook for her email; I use Thunderbird. Whenever she would send me an email with an attachment, it came to me as "winmail.dat", a useless item that I couldn't read. She tried fixing it on her end, but to no avail.

I found out about Lookout by reading a Mozilla help article, so I installed Lookout Fix Version 5.4 directly into Thunderbird as an add-on. (I am currently running Linux Mint 20.1, Xfce 64-bit, with Thunderbird version 102.15.1 64-bit.) This instantly solved the problem! No configuration was necessary! I was immediately able to read an email attachment that she sent to me.
