自作したOutlookアドインのツールヒントの無効化

Question

いつもいつもお世話になっております。

すごい勢いで質問してしまい申し訳ございません。

OutlookのVSTOアドインで自作したリボンにマウスホバーすると、ツールヒントが表示されるのですが、

ここの赤枠の箇所を、削除もしくは意図した文字に書き換えたいのですが、方法が分かりません。

Excelの自作したアドインのみでは、ここの部分を非表示にすることはできないという記事を見つけたので（すべてのアドインで表示、非表示を切り替えなければならない）、Outlookのアドインでも同様に

設定できないのではないかなと思います（自由に設定できるのは赤枠の上の部分までという認識）。

なにか参考になる情報など教えていただけないでしょうか。

宜しくお願いします。

美味しい魚屋さんさん、こんにちは。フォーラムオペレーターのHarukaです。
MSDNフォーラムにご投稿くださいましてありがとうございます。

既に見つけたように、その赤枠の箇所をカスタマイズすることはできません。
Office リボンはこの機能を公開しておらず、今後は公開するニュースもありません。

どうぞよろしくお願いします。
