How do I change the e-mail address of an existing account?

In some cases, an account is used in an active connection and the email address of this account is changed (e.g. in Microsoft 365). In this case, reauthentication is recommended (How do I reauthenticate an account?).

Please note: If it is a new account (delete and create a new one), this procedure is not possible and a new creation is necessary.
