This is odd to me, not sure what would cause this, as my three other mail providers (gmail, iCloud, yahoo) are working fine since the install. I hadn't changed any settings. It gives me the warning "Unable to verify account name or password". However I am still able to login via the web with my credentials, but I am using 2fa with Microsoft authenticator that way. I tried removing and re-adding the account in MacOS sys prefs, but it didn't help. MacOS doesn't ask for the authentication either, so I wonder if it's an issue with MacOS not being able to do the 2FA step? This is happening on both my desktop and laptop. Oddly my iPhone has no problem continuing to access hotmail via the Mail app and is using the Fiber via wifi. Anyone else encounter this?
