Microsoft Graphでメールを送信したフォルダを正しく読み取る方法は？

私のメールアドレスがに送信されました。 Graph ExplorerでMicrosoft Graphでメールを送信したフォルダを正しく読み取る方法は？

GET https://graph.microsoft.com/v1.0/me/mailfolders('outbox')/messages

、私は常に空の配列を取得：

{ 
    "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users('16f5a7b6-5a15-4568-aa5a-31bb117e9967')/mailFolders('outbox')/messages", 
    "value": [] 
}

を私は

GET https://graph.microsoft.com/v1.0/me/mailfolders

のみ送信済みフォルダ（送信トレイ）を実行したときに0電子メールを示しているが、実際にメールがありますフォルダに保存します。

フォルダを正しく読み取るにはどうすればよいですか？ありがとう
