Using Outlook for Android in business environments for email and scheduling
Sadly this s is not a fix. I contacted microsoft directly through the outlook app support request and was advised the launching in the outlook app internal browser is not configurable and is working as designed.
Perhaps even worse is links that refrr to apps i have installed like limkedin or amazon dont laumch the native app either and open the internal outlook browser. By this microsoft is ignoring the android config data that in my case is set to open these as "default apps'
Sadly i too will now remove this app.
