Important

APIs under the /beta version in Microsoft Graph are subject to change. Use of these APIs in production applications is not supported. To determine whether an API is available in v1.0, use the Version selector.

Create a draft of a new message in either JSON or MIME format.

When using JSON format, you can:

Include an attachment.
Use a mention to call out another user in the new message.
Update the draft later to add content to the body or change other message properties.

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.

By default, this operation saves the draft in the Drafts folder.

Send the draft message in a subsequent operation.

Alternatively, send a new message in a single action, or create a draft to forward, to reply or to reply-all to an existing message.

* Note: S/MIME message payloads are currently limited to 4 MB. Submission attempts that exceed this limit will result in anHTTP 413 Request Entity Too Large error response.

This API is available in the following national cloud deployments.

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

Permissions

One of the following permissions are required to call this API. To learn more, including how to choose permissions, see Permissions.

Permission type	Permissions (from least to most privileged)
Delegated (work or school account)	Mail.ReadWrite
Delegated (personal Microsoft account)	Mail.ReadWrite
Application	Mail.ReadWrite

HTTP request

POST /me/messages
POST /users/{id|userPrincipalName}/messages
POST /me/mailFolders/{id}/messages
POST /users/{id | userPrincipalName}/mailFolders/{id}/messages

Request headers

Name	Type	Description
Authorization	string	Bearer {token}.
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 representation of the message object.

When specifying the body in MIME format, provide the MIME content with the applicable Internet message headers ("To", "CC", "BCC", "Subject"), all encoded in base64 format in the request body.

To use mention to call out another user in the new message:

Include the required toRecipients property, the mentions property, and any writable message properties in the request body.
For each mention in the mentions property, you must specify the mentioned property.

Since the message resource supports extensions, you can use the POST operation and add custom properties with your own data to the message while creating it.

Response

If successful, this method returns a 201 Created response code and a message object in the response body.

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".

Examples

Example 1: Create a message draft in JSON format

Request

The following example shows a request to create a draft of a new message.

POST https://graph.microsoft.com/beta/me/messages
Content-type: application/json

Important

Microsoft Graph SDKs use the v1.0 version of the API by default, and do not support all the types, properties, and APIs available in the beta version. For details about accessing the beta API with the SDK, see Use the Microsoft Graph SDKs with the beta API.

For details about how to add the SDK to your project and create an authProvider instance, see the SDK documentation.
