Since last year, Microsoft is testing native notifications support for Microsoft Teams on Windows 10. The feature was available only as part of the public preview program. Now the company has started rolling out this feature to all Microsoft Teams users on Windows 10.
When you enable Windows 10's native notifications, Microsoft Teams notifications will be delivered through the Windows notification center. This will adhere to your device's Do-Not-Disturb (DND) settings and move to the Action Center if you miss the notifications.
