I don't even have a "Security and Privacy", just a "Privacy Settings", and then in there I don't see anything about Reset Advertising Id, just something like "Advertising Preferences" that has "Allow Outlook to s hare data to show you more relevant ads".

I think likely what I would have to do is add a personal email account to outlook, and then pay for a subscription on that, to get it to hide ads for my work email - but I don't really want to have to add a second email, I just want it for my work email, and then ideally I'd just pay through Play Store or whatever, but they don't even allow that.

Oh well. Maybe one day I will stop being lazy and find another email client that works well with my work email and has busy hours etc.
