    Hi @WardH ,

    Take a look at this get-message-content, you can get the entire mail response including attachments.
    The response is returned MIME, that body in plain text, body in html and also attachments with Base64 encoding.

    GraphServiceClient graphClient = new GraphServiceClient( authProvider );  
    var stream = await graphClient.Me.Messages["{message-id}"].Content  
    	.Request()  
    	.GetAsync();  
    

    To get attachments of message, use below snippet.

    GraphServiceClient graphClient = new GraphServiceClient( authProvider );  
    var stream = await graphClient.Me.Messages["{message-id}"].Attachments["{attachment-id}"].Content  
    	.Request()  
    	.GetAsync();  
    

    References:
    Get MIME content
    attachment-get

    Hope this helps.

    Im currently trying to download the data of an inlined image however the Attachments property of the email does not contain any elements. Its empty. If I look at the body of the message it does indeed have an < img > property but Attachments is empty.

    How to I get to the data of the inlined attachment?
