user: sendMail

Namespace: microsoft.graph

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.

This API is available in the following national cloud deployments.

Global service	US Government L4	US Government L5 (DOD)	China operated by 21Vianet
✅	✅	✅	✅

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.

Permission type	Least privileged permissions	Higher privileged permissions
Delegated (work or school account)	Mail.Send	Not available.
Delegated (personal Microsoft account)	Mail.Send	Not available.
Application	Mail.Send	Not available.

HTTP request

POST /me/sendMail
POST /users/{id | userPrincipalName}/sendMail

Request headers

Name	Type	Description
Authorization	string	Bearer {token}. Required.
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."
