How to reset Outlook 365 EDITOR settings to default?

[ringringhello]

I'm encountering problems with Outlook 365 as it consistently alters fonts when I import HTML files into the body of an email. For instance, where I've utilized <bold> with Arial, the editor changes the font to Times New Roman <strong>. Despite attempting to adjust all the editor settings, I haven't been successful. Interestingly, on another computer with the same version of Outlook, the font appears perfectly fine. I've also ensured that my settings match those of the other computer's Outlook.

Therefore, I am contemplating resetting the potentially corrupted Outlook to its default settings.
