Alternatives for SSRS Email Subscriptions After SMTP Deprecation in March 2026

Hi everyone,

We’re currently using SQL Server Reporting Services (SSRS) v15.0 with SMTP for email subscriptions. I’ve seen that Microsoft is disabling SMTP in March 2026, which means our SSRS subscriptions will no longer be able to send email notifications once that happens.

Since SSRS is a Microsoft product, I’d like to know what options or alternatives Microsoft recommends to continue delivering reports and alerts to users after SMTP is disabled.

Are there any planned updates or new delivery methods for SSRS subscriptions?

  • Is there a supported alternative?

Has anyone implemented a workaround or integration to replace SMTP-based delivery?

Any guidance or best practices from Microsoft or the community would be greatly appreciated.

Thank you!

    Hi Cristopher Aguilera,

    Thank you for posting your question in the Microsoft Q&A forum.

    Currently, Microsoft has not announced any official update to SSRS to support OAuth or new built-in delivery methods. The supported approach remains using SMTP relays or custom delivery extensions.

    After researching Microsoft’s official documentation and community guidance, I’d like to share the suggestions I found for handling SSRS email subscriptions once Basic Authentication for SMTP AUTH is retired in Exchange Online (March–April 2026).

    Continue using SMTP via a relay or modern service (recommended by Microsoft’s official article)

    Switch SSRS delivery method (workarounds)
    Use File Share delivery (built-in) and then distribute reports via Power Automate or scripts calling Microsoft Graph sendMail or ACS Email API.

    Since subscriptions in SSRS can have multiple recipients (to, cc), I'm not sure how Power Automate or scripts calling Microsoft Graph sendMail or ACS Email API, will be able to do this.

    Seems to me that you would have to statically set who gets the email in Power Automate for each folder it is monitoring.
