I haven't really been able to use outlook.office.com in anything but Edge, which on my Windows machine automatically authenticates with M365. In other browsers I regularly get stuck in an auth redirect loop between different Microsoft domains when I open the site. Sometimes it helps to clear all cookies and re-login (which is a real pain with 2FA and all) but it only ever helps once: If I close and re-open the site, I'll have to do it again.
How people voluntarily pay for this crap is beyond me. (In my case it's forced upon me by my client. On my own machines I switched to Linux in 2010 and never looked back.)
