Email Authentication changes

Note: These changes only impact IRIS Cascade customers who have moved away from the standard Cascade authentication (SendGrid) method to use another provider.

At the end of December 2026, Microsoft are removing support for Basic Authentication when sending emails and will be moving to an OAuth Modern Authentication. You will need to enter these new credentials into IRIS Cascade before the end of December 2026 for your system to continue sending emails.

We will be providing settings to support this new modern authentication in the very near future. Once released these settings will be found in a new area in Admin > Email settings.

Once released, all the email settings from System Properties will be in it's own area so this means you can assign access to this area in a role. You could give that role to your I.T. team so they can edit these settings themselves if needed.

If these settings are not changed before December 2026 your IRIS Cascade system may not be able to send any emails. This will impact workflow, requests, report schedules etc.

Please keep an eye on the release notes for confirmation when these settings will be available and how to use them. We are currently aiming for the May release.

For more details on the deprecation schedule, please see the Microsoft Exchange team blog

We will update this page with instructions and settings you'll need.

We will also be contacting the affected customers by email very soon.
