In the mail and calendar again show an advertising banner.
Microsoft has again begun showing a small banner ad in mail and calendar applications for the Windows 10 operating system.
Advertising is offered contextual and depends on user actions. For example, it offers an Outlook application for a mobile device, when a user reads mail through an Outlook.com account, and when using a Gmail account, a Gmail mobile application. Microsoft has already confirmed that ads cannot be disabled on the system.
