new MS Teams not working website outlook.office365.com

Hi all,
I have a problem in the new desktop version of MS Teams. When I insert the website outlook.office365.com into the website tab, it loads my emails on some computers. Specifically, on domain computers. However, when I try to open this website in the new Teams version on a different device than the domain PC, it doesn’t open the login window. It only loads the initial loading screen, and then the page stops displaying

Has anyone encountered the same problem? Is it somehow solvable?

Thank you very much for your help
