If you email accounts still show in setup and you just need to enter a password to validate, then that is the first thing to try.

Be aware whether your service requires you to use an app password or not. This is common when you have two-factor authentication enabled on the service. If you have been trying to log in with your regular password and getting an error, then look into app password. (Different services may call it differently. App password is what Microsoft calls it. When you understand the concept, it's the same with others, just maybe another name.)

If your email account was still in setup after the OS upgrade, waiting for you to validate, and you validate properly and still get an error, then delete the account from the device, power off the device, wait 15-30 minutes or so (SWAG) and then power on the device and try again. Make sure, though, that you know whether to use app password or your account password.
