Question

当对方拒绝会议并提议新的时间。在Outlook中，您可以看到建议的时间。

现在我正在尝试使用Microsoft Graph API来获得建议的时间。

例如，原始会议日期为 2018-03-08 ，另一人拒绝并建议新的日期 2018-03-12 。

我试过

GET /beta/me/messages/{messageId}=?$expand=microsoft.graph.eventMessage/event

但是，我无法从返回的结果中找到建议的时间。我怎么才能得到它？感谢

Answer 1

API不会直接公开此信息。相关实体没有定义显示此信息的字段。但是，数据显然存在，您只需要知道如何实现它。答案在于extended properties。

基本上，由于Graph没有公开这些值，我们需要深入研究存储此数据的MAPI属性。在对Exchange服务器协议文档进行了一些挖掘之后，我找到了PidLidAppointmentProposedStartWhole和PidLidAppointmentProposedEndWhole。我们只需要将这些MAPI属性定义转换为Graph扩展属性语法。

从文档中，这些都在PSETID_Appointment命名空间中，它使用GUID {00062002-0000-0000-C000-000000000046}。 PidLidAppointmentProposedStartWhole使用id 0x8250，PidLidAppointmentProposedEndWhole使用id 0x8251。所以那些应该转化为：

PidLidAppointmentProposedStartWhole：'SystemTime {00062002-0000-0000-C000-000000000046} Id 0x8250'
PidLidAppointmentProposedEndWhole：'SystemTime {00062002-0000-0000-C000-000000000046} Id 0x8251'

如果按照Get singleValueLegacyExtendedProperty我们在$expand子句中使用它们，我们会得到类似的内容：

GET /me/mailfolders/inbox/messages?$expand=singleValueExtendedProperties($filter=id eq 'SystemTime {00062002-0000-0000-C000-000000000046} Id 0x8250' or id eq 'SystemTime {00062002-0000-0000-C000-000000000046} Id 0x8251')

响应看起来像这样（省略了其他属性）：

{
    "subject": "New Time Proposed: Let's meet",
    "singleValueExtendedProperties": [
        {
            "id": "SystemTime {00062002-0000-0000-c000-000000000046} Id 0x8250",
            "value": "2018-03-20T20:00:00Z"
        },
        {
            "id": "SystemTime {00062002-0000-0000-c000-000000000046} Id 0x8251",
            "value": "2018-03-20T21:00:00Z"
        }
    ]
}
