我需要从 Exchange 2003 中的用户日历中提取所有非私人项目。我已经完成了以下工作，它会提取他们的所有项目（包括 Private 字段）：

<?xml version="1.0"?>
<g:searchrequest xmlns:g="DAV:" xmlns:mapi="http://schemas.microsoft.com/mapi/">
    <g:sql>
        SELECT "http://schemas.microsoft.com/mapi/Private", "urn:schemas:calendar:uid", "urn:schemas:calendar:location", "urn:schemas:httpmail:subject", "urn:schemas:calendar:dtstart", "urn:schemas:calendar:dtend", "urn:schemas:calendar:busystatus", "urn:schemas:calendar:meetingstatus", "urn:schemas:calendar:instancetype" 
        FROM Scope('SHALLOW TRAVERSAL OF "%s"') 
        WHERE NOT "urn:schemas:calendar:instancetype" = 1 AND "DAV:contentclass" = 'urn:content-classes:appointment' AND "urn:schemas:calendar:dtstart" > '2003/06/01 00:00:00' AND "mapiPrivate" = 0 
        ORDER BY "urn:schemas:calendar:dtstart" ASC
    </g:sql>
</g:searchrequest>

但是，当我尝试将 Private 字段添加到时，WHERE我得到一个BAD REQUEST错误响应。以下代码是我将 Private 字段添加到WHERE子句的方式。

<?xml version="1.0"?>
<g:searchrequest xmlns:g="DAV:" xmlns:mapi="http://schemas.microsoft.com/mapi/">
    <g:sql>
        SELECT "http://schemas.microsoft.com/mapi/Private", "urn:schemas:calendar:uid", "urn:schemas:calendar:location", "urn:schemas:httpmail:subject", "urn:schemas:calendar:dtstart", "urn:schemas:calendar:dtend", "urn:schemas:calendar:busystatus", "urn:schemas:calendar:meetingstatus", "urn:schemas:calendar:instancetype" 
        FROM Scope('SHALLOW TRAVERSAL OF "%s"') 
        WHERE NOT "urn:schemas:calendar:instancetype" = 1 AND "DAV:contentclass" = 'urn:content-classes:appointment' AND "urn:schemas:calendar:dtstart" > '2003/06/01 00:00:00' AND "mapiPrivate" = 0 AND "http://schemas.microsoft.com/mapi/Private" = 0
        ORDER BY "urn:schemas:calendar:dtstart" ASC
    </g:sql>
</g:searchrequest>

我究竟做错了什么？这不可能吗？

您需要请求 PR_SENSITIVITY 属性（DASL 名称http://schemas.microsoft.com/mapi/proptag/0x00360003）。对于私有 apppoitments，其值为 SENSITIVITY_PRIVATE (=2)
