Send internal email action retirement

Microsoft announced the retirement SharePoint SendEmail API, known as SP.Utilities.Utility.SendEmail, which is utilized to send internal SharePoint emails. It is getting retired on October 31, 2025.
This means all email notifications send through this method will stop to work. This change affects skybow Send internal email action that has used this method. The action Send internal email will no longer work in SharePoint Online after October 31, 2025. 

With the latest update, end users will now see the following notification message:

To keep send email functionality, you must migrate Send internal email to the Send email action. You can perform the migration in one of the following ways: 

Migration steps for the solution in Teamsware studio

  • When you navigate to the solution, dialog window appears on startup if your solution contains any Send internal email action in one of the features. 

    Note:  The 'Actions retirement' dialog will continue to appear on startup as long as there are any Send internal email actions remaining in the solution and the Show this dialog on startup option is checked.
    Note: You can skip the Migration step for the whole solution, and do migration for feature or for individual action (see below). 


  • Click the 'Migrate' button in the dialog window.
    Note: Before migrating, please ensure all changes to the form are saved; otherwise, any unsaved changes will be lost. 
    Note: Send email action in Modern Forms, List Actions and Automation Actions requires to approve API access request with 'Mail.Send' permissions. This should be done once per tenant by a tenant admin.

  • Click the "Migrate" button displayed on the action. This will automatically switch the configuration to the new Send Email action. All previously configured settings will be saved. After the migration is complete, you need to finish configuring the Send Email action. Please follow the steps below: 

    • Approve API Permissions (This should be done once per tenant by a tenant admin.):
      for Modern Forms:  
      - Mail.Send — required to send emails.  
      -  Mail.ReadWrite — required only if the total size of attachments exceeds 3 MB. 

      for Scheduled/Triggered actions: 
      - Teamsware Exchange Connector - required to send emails. 

  • Configure Additional Options: Additional settings for the Send Email action can be adjusted as needed. These include fields such as Attachments, Fallback, Show before send and others.  


Migration of the Send Mail action in Rich Forms and Action Links can be done individually for each action. To migrate Send Mail action, follow these steps:   

  • Ensure versions are up to date. Before migrating, please ensure that the versions of Rich Forms and Action Links are up to date. If not, update them to the latest versions. 

  • Open Action Builder with Send Mail action. On the Action Builder click on 'Migrate' button. This will automatically switch the action to use Microsoft Graph Send Mail API. All previously configured settings will be saved. 

    Note: Please, make sure you have approved the Microsoft Graph 'Mail.Send' delegated permission for the SharePoint Online Web Client Extensibility. This should be done once per tenant by a tenant admin.
    Note: In Send Mail action, emails cannot be sent from external users.



Important

Important: After October 31, 2025, the Send internal email action will be automatically switched to the Send email action — only if the Teamsware Exchange Connector has been approved for the tenant in the Scheduled/Triggered actions. 

Important: In Send email action, emails cannot be sent from external users in Modern Forms, List Actions and Automation Actions.

Important: In SharePoint On-Premises 2019 and SharePoint Subscription Edition (SE), the Send email action functions as Send internal email. The following options: Attachments, Show before send, Save to sent items, Fallback will not work. These limitations are due to platform constraints in on-premises SharePoint environments.

Important: If you have active deployments, please make sure after migration create new package and update deployment for all target sites. Best to do this before retirement date.

Additionally, you are able to identify usage of the retired API via the Purview audit logs in the admin center (Admin center -> Microsoft Purview):

  3. Select a date range to run the audit search for (recommend running it for at least 90 days)
  4. Put the following text, “SendEmailApiInvoked” into the “Activities – operation names” textbox and click search.
  5. The request will be queued, and results will be available once processed.
  6. Click on the results and review each of the items.
