Summary:
The SharePoint Utility.SendEmail API will retire on October 31, 2025. Tenants should identify usage via Purview audit logs and update any custom code or Power Automate flows using this API. Alternatives include Microsoft Graph SendMail API and Outlook connector in Power Automate.
Details:
Updated October 1, 2025: As previously announced in the October 31st, 2024, post, we will be retiring the Utility.SendEmail API on October 31st, 2025.
As a reminder, you are able to identify usage of the API via the Purview audit logs in the admin center
As a tenant admin, navigate to the Microsoft Purview Portal available within the Microsoft 365 Admin Center.
Open Audit to search for activities.
Select a date range to run the audit search for (recommend running it for at least 90 days)
Put the following text, "SendEmailApiInvoked" into the "Activities - operation names" textbox and click search.
The request will be queued, and results will be available once processed.
Click on the results and review each of the items.
Use the UserAgent and ApplicationDisplayName to help identify the caller.
[NOTE:] If the ApplicationDisplayName = "Workflow" then the items will be unaffected by this API retirement but will follow the SharePoint 2013 Workflow retirement. We will be retiring the Utility.SendEmail API from SharePoint. The SP.Utilities.Utility.SendEmail could be used to send emails from custom applications or processes within SharePoint Online, including Power Automate, and custom workflows.
From custom code the API can be referenced via REST as ("/_api/SP.Utilities.Utility.SendEmail") while for CSOM, it would be "Utility.SendEmail" with more information on the original implementation at Utility.SendEmail method for CSOM.
