Hello All,

When I am trying to send mail I am facing this type of issue.

Error:- the SMTP server rejected the authentication request, as the authentication data is incorrect. verify that your username and password are correct and that the SMTP server supports the specified authentication type (basic). SMTP error code: 535.

Hi, are you using an App Password for your email account? That is needed if you have MFA required for your email account.

Below link will help you to create app password.
