That was quick! 😀
Replace Microsoft Outlook with Thunderbird. Thunderbird is a Mozilla based (Firefox) email program, uses all the same settings and even runs on Windows.
Better yet, bypass the whole Windows operating system and sideload Linuxmint. I did a dualboot on my husband’s Windows—trying to wean him off of Microsoft—so it boots either a brand new Linux or your old Windows, so you can have both.
