Help with Outlook troubleshooting

I've been using the Outlook app for Windows 11 for a while now for work. My company went to using a 2-factor authentification system where you have to type in a code they send to your phone almost every time to log in. Now on my computer, the Outlook app won't load any of my emails and it's not even requesting to send a code. I've reloaded the send/receive button a bunch of times and I've also updated the app to no luck. Any advice on what to do? Also, the app on my taskbar has an exclamation mark (!) for some reason I can't figure out.
