New Outlook - Link functionality not working properly

Recently in the new Outlook environment a change was made to the way Links are handled. It used to be so that when I clicked a link, a new tab was opened in my edge browser. Since this week suddenly a new window opens (looks like EdgeWebview) that doesn't accommodate my web plugins (Dashlane) nor calls upon cookies to prefill fields.

So for example when i follow a link to new courses on the Learning Platform, it forces me to log in manually. Of course I can rightclick copy paste the link, but it is still a nuisance. 

All information i could find refer to older documentation and functionalities that are not present in the current settings menu.  

Does anyone have a clue how to change the behavior for handling hyperlinks within outlook?
