message: forward

Namespace: microsoft.graph

Forward a message using either JSON or MIME format.

When using JSON format, you can:

• Specify either a comment or the body property of the message parameter. Specifying both will return an HTTP 400 Bad Request error.
• Specify either the toRecipients parameter or the toRecipients property of the message parameter. Specifying both or specifying neither will return an HTTP 400 Bad Request error.

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 forward a message, and send it later.
