Hi,

I can suggest you to check with the IT team if they have provided the correct ID and password, if that is incorrect then this error comes.

Hi Ramit,

Thanks for your answer

I get the error when i Username and password :

Mail authentication failed. Please verify your SMTP user name and password. If your SMTP server doesn't support authentication, please clear the SMTP user name and password. Server smtp.office365.com:587 using SSL/TLS supports the following authentication options: LOGIN, XOAUTH2.

Hi,

You need to select the ID and password, after that check the connection by 'Test Connection' option
