Send the message specified in the request body using either JSON or MIME format.

When using JSON format, you can include a file attachment in the same sendMail action call.

When using MIME format:

  • Provide the applicable Internet message headers and the MIME content, all encoded in base64 format in the request body.
  • Add any attachments and S/MIME properties to the MIME content.

This method saves the message in the Sent Items folder.

Alternatively, create a draft message to send later.

To learn more about the steps involved in the backend before a mail is delivered to recipients, see here.

Permissions

Choose the permission or permissions marked as least privileged for this API. Use a higher privileged permission or permissions only if your app requires it. For details about delegated and application permissions, see Permission types. To learn more about these permissions, see the permissions reference.

POST /users/{id | userPrincipalName}/sendMail

Request headers

Name Type Description
Authorization string Bearer {token}. Required. Learn more about authentication and authorization.
Content-Type string Nature of the data in the body of an entity. Required.
Use application/json for a JSON object and text/plain for MIME content.

Request body

When using JSON format, provide a JSON object with the following parameters.

Parameter Type Description
message Message The message to send. Required.
saveToSentItems Boolean Indicates whether to save the message in Sent Items. Specify it only if the parameter is false; default is true. Optional.

When specifying the body in MIME format, provide the MIME content as a base64-encoded string in the request body.

Response

If successful, this method returns 202 Accepted response code. It doesn't return anything in the response body.

Note: A 202 Accepted response code indicates that the request has been accepted; however, it does not indicate that the request processing has completed. Delivery of the message is subject to Exchange Online limitations and throttling.

If the request body includes malformed MIME content, this method returns 400 Bad request and the following error message: "Invalid base64 string for MIME content."
