Configuring Ecostruxure IT Data Center Expert to use Oauth for SMTP

[Curly71]

Microsoft have stated :

During September 2025, we will remove support for Basic auth with the Client Submission (SMTP AUTH) endpoints:

smtp.office365.com
smtp-legacy.office365.com 

Once Basic auth is permanently disabled, any clients or apps connecting using Basic auth with Client Submission (SMTP AUTH) will receive this response:

550 5.7.30 Basic authentication is not supported for Client Submission.

Can anyone advise if DCE supports OAuth for SMTP

Hi @Curly71,

Thanks for this question. Engineering has logged it.

Keep an eye on DCE release notes for information on future releases.

Best,
