Excel VBAを使用して、受信した電子メールの毎日の集計をOutlookからファイルにエクスポートする

そのため、Outlookの1つのフォルダーについて、毎日受信した電子メールの数の集計をエクスポートできる場所を見つけました。問題は、何百ものフォルダーに対してこれを行う必要があるため、メインフォルダー内のすべてのサブフォルダーを調べようとしたことです。これは、1つのフォルダーを調べている場合は正常に機能し、非常にうまくエクスポートされます。自分の能力の限界に達したと思います。私は正しい方向に向かっていますか、それとも非常に非効率的な道に向かっていますか？

本当に解決策に近いので、クラッシュするだけです。何万通ものメールがあるからかもしれません。
