Question

我需要检索和检查委托转发规则（EWS中的内置委托命令不足以满足我的需求，因为它们阻塞了用作委托的组。）

我能够成功找到“Schedule+ EMS Interface”创建的规则。但是，我无法检索PR_RULE_ACTIONS。打开跟踪。

我看到PidTagRuleMsgProvider属性返回正常，但PR_RULE_ACTIONS永远不会。

我怀疑我在属性集定义中使用了错误的MAPI属性类型，但我已经浏览了http://msdn.microsoft.com/en-us/library/exchangewebservices.mapipropertytypetype(v=exchg.140).aspx中列出的所有内容。有线索吗？

以下是相关的代码片段：

Answer 1

PR_RULE_ACTIONS的属性标记是0x668000FE。你可以在OutlookSpy中看到它（和属性数据） - 转到收件箱文件夹，单击IMAPIFolder按钮，转到PR_RULES_TABLE选项卡，选择规则，双击PR_RULE_ACTIONS属性。

Glen Scales能够让我走上正确的道路。事实证明，PR_RULE_ACTIONS不是通过EWS公开的，而是通过名为PR_EXTENDED_RULE_ACTIONS的属性公开的相同数据。现在，我很高兴地抛出代码来解析二进制blob。

如何通过PowerShell和EWS托管API检索PR_RULE_ACTIONS？
