How to get MIME content of Office365 mail using Microsoft Graph API?

How to get MIME content of the Office365 mail using Microsoft Graph API so that i can create EML file?

Or is there other way to create EML file of the mail found in Office365 using Microsoft graph API?

I have already tried using EWS API but want to use Graph API.

Thanks in advance

As per the (Official documentation)

MIME is an industry email standard. Many email applications create messages in MIME format and save them in files with the .EML extension.

Even though Outlook does not save messages in MIME format, there are two ways you can get an Outlook message body in MIME format:

You can append a $value segment to a get-message operation on that message. If the message is attached to an Outlook item or group post, you can append a $value segment to a get-attachment operation on that item or group post.

GET /users/{id}/messages/{id}/$value

If the message is attached to another message in the user's mailbox:

GET /users/{id}/messages/{id}/attachments/{id}/$value

Example

The following is an example that requests a message in the signed-in user's mailbox to be returned with its MIME content.

GET /me/messages/4aade2547798441eab5188a7a2436bc1/$value

The following is the response. The MIME content begins with the MIME-Version header.

Microsoft Graph have an API to returning MimeMessage. That is

https://graph.microsoft.com/beta/me/messages/{Id}/$value

You should replace Id by your message Id. Then read response as stream and then it load to MimeMessage.

There is no support for MIME in Graph or Exchange REST at this time. Use EWS.
