Microsoft has once again turned on the small banner ads in the Windows 10 Mail and Calendar UWP apps, according tomedia. The ads were last seen in November last year, when Microsoft called them an experiment. At that time, the ad would only appear in apps for non-Office 365 users, but now it appears in front of every user and doesn’t seem to be deleted.
These ads aren’t fixed — when you read Gmail, it recommends that people read Gmail on their phone, and if they’re reading Outlook.com, they’ll give outlook software-related recommendations.
But it’s a bit annoying for users to see ads and take up a lot of vertical space in the menu, even if they end up reading on the mobile client.
In response, Microsoft said: “No matter which email address you use, the ads for the app itself will appear.” It is non-deleteable, but you can submit suggestions in the Feedback Center of Windows 10: https://msft.it/6012TVPXG. “
