Mail Handling Integration - In September 2025 Microsoft Exchange Online to retire Basic auth for Client Submission (SMTP AUTH)
Are there plans for supporting more modern authentication methods (e.g., oauth2)?
I imagine that there are quite a few customers that use Microsoft Exchange (office365) as a relay and will be affected by the retirement of basic auth for Client submission. What, if any, are your plans for handling this?
Thank you

Hello,
Instead of enhancing the SMTP authentication, we’ll be following Microsoft recommendations and support sending emails by calling MS Graph APIs.
Thank you,
