Your login session at work lasts exactly 168 hours (24*7) and at 168 hours and one minute, you get two MFA prompts simultaneously. You can't click on Outlook yet because the MFA system "didn't hear from you". After logging on, you join your daily Teams standup anonymously, because you don't have time to dig through dialog boxes that ding at you when you click on them to find the one with the working login button. A password prompt appears for a moment, you start typing, then it disappears again.
