What about OAuth? Microsoft sunsetting SMTP Auth by Sept 2025

Feedback

When will OAuth be available for Email authentication? Our IT team notified me that Microsoft has announced the deprecation of Exchange Online Basic Authentication for SMTP Auth (client submission) effective September 2025.

After this date, the SMTP Authorization method Metabase uses to relay email via Microsoft 365 will no longer be supported by Microsoft.

What is the work-around for this? Will Metabase join the more modern authentication method and support OAuth for its users?

Microsoft recommends their Azure Communication Services for sending email with SMTP authentication.

I've found it much easier to just use a 3rd party SMTP server. I use SMTP2Go, the free version provides enough volume for most uses.
Just means modifying your SPF record to allow a new sending server.
