PythonでOutlook電子メールデータを抽出中にエラーが発生しました

os.walkとwin32com.clientを使用して、C：ドライブのフォルダとそのサブフォルダからOutlook電子メールファイル（.msg）から情報を抽出するPythonスクリプトがあります。それは動作するように見えますが、返されたデータフレームで何かをしようとすると（emailData.head() Pythonがクラッシュするなど）。パーミッションエラーのため、データフレームを.csvに書き込むこともできません。PythonでOutlook電子メールデータを抽出中にエラーが発生しました

私のコードがoutlook /各メッセージを適切に閉じていないのか、それが問題の原因ですか？どんな助けもありがとう。
