No system notifications in Windows for Outlook mails and calendar event reminders

Hi Patrick,

It seems that Microsoft uses Google Push Notifications (Firebase Cloud Messaging). You can also test it on this site:

Or when you look in the browser console you will find a line like “owa.414231.m.js:1 Uncaught (in promise) DOMException: Registration failed - push service error” originating from a microsoft domain, e.g. “”.

Solution: Go to “brave://settings/privacy” and check the first switch “Use Google Services for Push Messaging” and restart the browser.
