SMTP outlook.com basic authentication

Hello,

since yesterday, our mails sent from ReportServer (versions RS3.0.3-6000 CE and RS4.6.1-6098 CE) are giving errors.

When trying to send to SMTP server (outlook.com), mails are being refused giving this error:

Caused by: javax.mail.AuthenticationFailedException: 535 5.7.139 Authentication unsuccessful, basic authentication is disabled. [MA3P292CA0009.ESPP292.PROD.OUTLOOK.COM 2024-09-18T09:25:58.315Z 08DCD4EF15313DF1]

Current configuration for mail.cf is

<?xml version="1.0" encoding="UTF-8"?> smtp-mail.outlook.com 587 username@outlook.com password false true false ReportServer username@outlook.com true allow_mixed

I have tried changing several combinations for “ssl, tls, enable, require”, but no way.

Could you please help ?

Thanks

Alfredo

Hi Alfredo,

A quick search suggests that Outlook has deprecated basic authentication, as outlined in this link:
Deprecation of Basic Authentication in Exchange Online: https://learn.microsoft.com/en-us/exchange/clients-and-mobile-in-exchange-online/deprecation-of-basic-authentication-exchange-online
However, this specifically applies to Exchange Online, and I’m not certain if it affects ReportServer as well. Regardless, we’ve raised ticket RS-8658 and will investigate further.

Regards,
Eduardo

Thanks Eduardo,

yes, we know it.

The matter is to have a workaround to be able to send messages as it has happened until yesterday.

Excuse me Eduardo.

We know it = we know that Outlook has deprecated basic authentication.
