Email not sending on iPhone

Hi, I am having a very big problem with the mail app in iOS 16. I have two emails set up and when I reply to a email, it can’t send, it just goes straight to my outbox and a error message says server not found. I tried everything, I looked to see if my server for the emails is turned on and it is and I also re-added my two emails again and it still did not fix the problem. I did not change anything about my two emails since I had iOS 15. In iOS 15, did not have these problems but now I do. This is definitely a iOS 16 problem.

No it is definitely an email account that wasn’t set up correctly. An email account accesses 2 servers, one for incoming email and a different one for outgoing email. Each requires a user ID and password to be set up for each email account that you use. Usually the easiest way to fix this problem is to go to Settings/Mail/Accounts, tap on and delete the account with the problem, then restart your phone, and go back to the same setting and add it back. When you add an email this way iOS will ask the server what the correct settings are, and set up both incoming and outgoing.

Any time you change your email password you have to change it in two places, for incoming and for outgoing (SMTP). Or, just delete the account, restart, and add it back.
