If you're having trouble setting up your app or client or you are no longer able to send and receive emails you may need to make a change to your password.
If the client or app does not meet modern security standards we may ask you to generate a special 16 character password to enter alongside your login credentials.
Please read this article and click on the "Generate a new app password and update your settings" link. You will be guided through the process of generating the 16 digit pass and setting up your email client with it.
