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 to reply to the sender of a message in either JSON or MIME format.

When using JSON format:

Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.
If replyTo is specified in the original message, per Internet Message Format (RFC 2822), you should send the reply to the recipients in replyTo, and not the recipients in from.
You can update the draft later to add reply 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.

Send the draft message in a subsequent operation.

Alternatively, reply to a message in a single operation.

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.ReadWrite	Not available.
Delegated (personal Microsoft account)	Mail.ReadWrite	Not available.
Application	Mail.ReadWrite	Not available.

HTTP request

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

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.
Prefer: outlook.timezone	string	Sets the time zone for the `Sent` field of the reply draft message in HTML that this API creates based on the request body. The value can be any of the supportedTimeZones configured for the user. If not specified, that `Sent` field is in UTC. Use this header only if you're specifying the `Content-Type: application/json` header to create the reply draft message in HTML. If you use the `Content-Type: text/plain` header, this `Prefer` header does not have any effect. Optional.

Request body

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

Parameter	Type	Description
comment	String	A comment to include. Can be an empty string.
message	message	Any writeable properties to update in the reply message.

When specifying the body in MIME format, provide the MIME content with the applicable Internet message headers, all encoded in base64 format in the request body.

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".

Examples

Example 1: Create a draft in JSON format to reply to an existing message

The following example creates a reply draft, adds a comment and a recipient in the request body.

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.
