Microsoft is making a significant change that could impact your OpCon environment. Beginning September 2025, Microsoft will retire legacy authentication methods (Basic Auth) for Exchange Online, requiring all users to transition to Modern Authentication (OAuth 2.0).
Why This Matters
Once Microsoft deprecates Basic Authentication, any OpCon job using SMTP Basic Auth for email notifications will fail to authenticate, causing emails not to send. Identifying affected systems now will help ensure you transition smoothly to Modern Authentication without disruptions.
What This Means for You
If your OpCon environment relies on email notifications sent via SMTP Basic Auth to authenticate with Exchange Online, your jobs may fail to send emails once this change takes effect. That means critical notifications might not reach your teams, potentially disrupting your automation workflows.
OpCon Cloud customers using the Relay component are NOT affected.
To ensure a smooth transition and assess the impact on your environment, we need your input.
How to Check Your Setup
Please confirm the following:
- Are you currently using email notifications in OpCon?
- Is the SMTP account for OpCon notifications a Microsoft Exchange Online account?
- If “yes” to both of the above, what is your OpCon version?
Action Required
If you answered “yes” to both Question 1 and 2, please reply to support@smatechnologies.com as soon as possible with your OpCon version to open a support ticket.
How to Find Your OpCon Version (On-Prem Customers only)
