Office365 O365合规性搜索硬删除不工作

用户删除的邮件中有超过40GB的电子邮件。她已经证实，她不需要它们来恢复

我已经使用这里概述的方法运行了一个搜索来提取她的“已删除邮件”文件夹id

然后，在2020年3月30日之前，我在合规中心为她的用户创建了一个搜索，以文件夹id作为搜索词进行搜索。搜索返回20 GB以上的结果

我使用connect IPPSession通过2fa连接到法规遵从性服务 并运行以下命令

新合规性搜索行动-搜索名称“2020年3月30日之前删除的项目”-清除-PurgeType硬删除

动作立即完成显示

结果：吹扫类型：硬删除；项目计数：0；总尺寸0；详细信息：{}

用户邮箱的大小根本没有缩小，所有已删除的邮件仍然存在。再次运行搜索将返回相同的20+GB结果

我尝试了软删除和硬删除选项，结果是一样的，什么都没有发生

---

我已通过Get ComplianceSearch确认，powershell中显示的搜索名称的数据估计为20GB，那么为什么HardDelete没有删除任何内容？

因此我了解到清除操作一次只能删除10个项目。至于为什么你和我没有看到任何电子邮件被删除，我从来没有完全弄清楚。我怀疑每次运行都会删除10个邮箱，但由于我搜索了多个邮箱（根据我的要求），结果不清楚。从那以后，我成功地使用了一个脚本（如下所示），我根据自己的需求对该脚本进行了调整

非常感谢Tony Redmond，我修改了他的剧本
