狀況
假設您建立就地 eDiscovery 搜尋在 [Exchange 系統管理員中心 (EAC) 以傳回由指定送到外部收件者的項目不收件者:"internalDomain"準則，在搜尋]。在此情況下，搜尋語法會傳回給只外部收件者，會傳送的項目，但是不包括內部和外部的收件者的項目。
原因
之所以發生這個問題，是因為 eDiscovery 使用關鍵字查詢語言 (KQL) 所使用的布林邏輯。因此，不收件者:"internalDomain"排除所有的項目包含了內部的收件者，甚至也有外部的收件者的項目。注意目前的設計並不會提供透過 [EAC 去蕪存菁的功能。
因應措施
若要解決這個問題，您可以使用下列方法之一。
方法 1︰ 使用 EWSEditor
若要解決這個問題使用釋放波EWSEditor應用程式。沒有 [eDiscovery] 視窗它可以用來搜尋項目。注意您必須設定讓稽核 RBAC 角色所使用的帳戶來執行這些搜尋。
方法 2︰ 使用不同的 API
使用不同的 API，不會依賴 KQL。您必須使用其他程式，例如 「 Exchange Web 服務 」 (EWS)，以建置自訂的解決方案。方案可以擷取資料 （較大的資料集） 的某些部分。方案可以進一步處理接收到的結果，使用外部的邏輯，來到達您想要的相符的訊息集是不收件者:"internalDomain"的標準為您會將它解譯。此外，為身份識別的發展這類訊息，更好的解決方案就是使用傳輸規則，可以將這類項目 （內部及外部收件者） 的副本傳送給稽核的信箱。以下是程式碼範例，如果要解決這個問題，使用 EWS 管理 API。注意在這個程式碼範例中，InternalDomain1.com、 InternalDomain2.com、 InternalDomain3.com 以取代您的內部網域名稱。這個版面配置區會出現在程式碼中的三個位置中。

方法 3︰ 預防監視為項目具有內部和外部的收件者的身份識別，建立傳輸規則，可以將這類項目的複本傳送到稽核的信箱。
