症状
假设您在 Exchange 管理员中心 (EAC) 返回通过指定发送给外部收件人的项目创建一个适当 eDiscovery 搜索不收件人:"internalDomain"中的搜索条件。在此情况下，搜索语法返回发送到仅外部收件人，项目，但不包括内部和外部收件人的项目。
原因
出现此问题是因为 eDiscovery 使用关键字查询语言 (KQL)，使用布尔逻辑。因此，不是收件人:"internalDomain"包含内部收件人，甚至还有外部收件人的项目的所有项目中都排除。注意：当前设计方案没有提供通过 EAC 更为精致的功能。
解决方法
要变通解决此问题，可以使用下列方法之一。
方法 1︰ 使用 EWSEditor
自由软件EWSEditor应用程序可以用来变通解决此问题。没有可用于搜索的项的 eDiscovery 窗口。注意：您必须设置用于审核 RBAC 角色的帐户执行这些搜索。
方法 2︰ 使用不同的 API
使用不依赖于 KQL 使用不同的 API。您必须使用其他程序，如交换 Web 服务 (EWS) 构建自定义解决方案。该解决方案可以检索数据 （大数据集） 中的某些部分。使用外部逻辑来达到所需的一套相匹配的消息，该解决方案可进一步处理接收到的结果不收件人:"internalDomain"的标准为您会将其解释。此外，为今后此类消息的标识，更好的解决方案是使用传输规则，可以将此类项目 （内部和外部收件人） 的副本发送给审核的邮箱。下面是示例代码，以使用 EWS 托管 API 变通解决此问题。注意：在此代码示例中，替换为 InternalDomain1.com、 InternalDomain2.com、 InternalDomain3.com 您内部域的名称。此占位符出现在代码中的三个位置。
