time machine – Apple Mail will not connect after Migration Assistant transfer

I've recently used Migration Assistant to import data to a new Mac Mini from a Time Machine backup on my old Mac. After I finish, I can not log in to my email account because the error "Can not verify the account name or password". I know for sure that my password and account are correct because I can always connect to this email account on my old computer with the help of this login information.

I have tried:

  • restart
  • delete the existing email account and try to add the account again
  • Deleting the keychains associated with the mail of my access to the keychain under "connection"

Any help would be appreciated. Thank you!
