'Something went wrong. 5ssai.

I was able to get everything working again by resetting MFA here: https://entra.microsoft.com/.  Apparently after October 2024, if you try to setup a new phone it seems to error out until the MFA stuff is reset and I think enabled. It doesn't affect logins already established but it affects ones on new devices.

Here's an article on Godaddy that seems to cover the topic on how to reset it: I can't access my multi-factor authentication method | Microsoft 365 from GoDaddy - GoDaddy Help US

Good Luck!

Samsung sent me this and it worked! I turned my phone off for 5 mins otherwise followed instructions

Clear the cache of the app.

To clear an app's cache:

1. From the home screen, swipe either up or down to access apps.
2. Select Settings.
   3. Select Apps.
3. Select the sort by icon next to 'Your apps'.
4. Select the switch next to****'Show system apps' and select OK.
5. Select the appyou'd like.
6. Select Storage.
7. Select Clear cache.

Please note: this should not remove any saved game data.

Turn your device off for 20 seconds, and then turn it back on again.

Open the app again.

UPDATE:- I have my family Microsoft account that I use for my work docs and I also have a Microsoft account that is run through my website and email provider THIS was the one that needed to be set up for emails on my phone
BUT the issue was it needed to be completed at the backend through my website provider because MICROSOFT had locked all external providers out of their system (by woopsy) and all necessary passwords to be reset
Oh and stay away from the Microsoft authenticator app - it is terrible
