Gross. Using the “New Outlook” that was forced on me, and there’s a sneaky ad at the top of my inbox, designed to look like an email, even though it isn’t. Accidentally clicking it - I didn’t notice the “Ad” box at first, and assumed it was a marketing email - opens a browser window that triggers a uBlock rule. And this is happening to a paying MS365 customer!

An advert from Canon in the New Microsoft Outlook, designed to look like an unread email in the inbox list. It has a tiny Ad marking but  otherwise looks identical to a regular email
