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.

Reply to all recipients of a message using 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 the original message specifies a recipient in the replyTo property, per Internet Message Format (RFC 2822), send the reply to the recipients in replyTo and not the recipient in the from property.

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 to reply-all to a message, and send it later.

This API is available in the following national cloud deployments.
