this is the new "Outlook" that Microsoft forces on users that require an Outlook account because they e.g. own stuff via the Microsoft store. I opened it for the first time and clicked on the first mail, since I was confused with whom I had shared this dummy mail address.
Outlook OPENED A LINK IN A BROWSER WINDOW DIRECTLY. IT STARTED THE BROWSER AND OPENED THE AD LINK. THIS SCARED ME SO MUCH! before I noticed it said (Ad)
fuck microsoft btw
