Thank you for the kind review!

MACでOutlookユーザーに朗報

仕事上Windows版 Outlook .msg メールの保存が必須で過去分膨大なメールをMACのみで閲覧することが出来ずに困り果てていました。この為だけにParallelsに課金するのもバカバカしく、ひょんなことからこのアプリの存在を知り非常に便利で感激しています。
問い合わせや不具合への真摯な対応も好印象です。別途、PST Viewwerも購入し便利に活用させていただいています。お薦めです。

I paid 1,500 yen, but the header isn't showing up in the PDF file.
