Create message

Namespace: microsoft.graph

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

When using JSON format, you can:

Include an attachment to the 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 operation, or create a draft to forward, reply and reply-all to an existing message.

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}. Required. Learn more about authentication and authorization.
Content-Length	number	0. 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 representation of 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.

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 201 Created response code and 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".
