Hello Eliane Palorca Jakowatz,

Thank you for reaching out to the Microsoft Community. We are happy to assist you.

It appears you are experiencing an SMTP server authentication issue, as indicated by the SmtpSubmissionPermanent5XXException error. This error typically arises when the SMTP server requires a secure connection or the client was not authenticated correctly.

To better address the issue, kindly provide details regarding the following inquiries:

1. Could you please confirm which email service you are using? Have you checked their SMTP server settings? Ensure that the SMTP server settings in Outlook are configured correctly, including the server address, port number, and authentication requirements.
2. If you have recently changed your email password, please make sure to update it in Outlook as well.
3. Have you verified that the authentication method you are using is supported by your email server? If not, you may need to contact your email server administrator for this information.

Providing this information will help us gain a better understanding of the issue.

We sincerely appreciate your cooperation and patience in this matter. Wishing you all the best!

Sincerely
