That's just what Outlook, already the most targeted email system, needs! Ads from Microsoft that make the phishing emails seem more plausible.
This is a footgun second only to ActiveX.
What a backwards rationale. Instead of growing the user base of the app and try to allure people to office 365, they chose to pester potential future clients.
I see no ads using uBlock Origin.
There no uBO for mobile devices / browsers.
uBlock Origin works on Firefox for Android, but it won't help with the Outlook app.
I already uninstalled Outlook on Android because it added an unremovable "Search with Bing" option to the browser context menu. At least the web version will be subject to adblockers now.
That't why i don't use it.
"-Doctor, if i hit my face it hurts. - Don't do it then."
Well, can't see ads if you are using a third party email client.
