C# EWS保存每个日历约会的Guid
我需要为每个约会保存一个Guid。 我曾尝试使用C# EWS保存每个日历约会的Guid,c#,guid,exchangewebservices,exchange-server-2010,C#,Guid,Exchangewebservices,Exchange Server 2010,我需要为每个约会保存一个Guid。 我曾尝试使用PolicyTag和ArchiveTag，但得到了一个 “属性PolicyTag仅对Exchange 2013或 以后的版本。” 例外 我们是否为Exchange 2010提供了类似的服务？ 据我所知，有一个appointment.ID包含自己生成的ID。 我宁愿不使用它。 谢谢。解决此问题的一种方法是创建一个扩展属性，并为约会放置guid，除非您从另一个约会复制了一个副本，否则它不会更改（毕竟它只是一个属性） 此解决方案在单一预约和使用本地Exc
PolicyTagArchiveTagappointment.ID谢谢。解决此问题的一种方法是创建一个扩展属性，并为约会放置guid，除非您从另一个约会复制了一个副本，否则它不会更改（毕竟它只是一个属性） 此解决方案在单一预约和使用本地Exchange的情况下都非常有效。这里的问题是，对于在线Web访问（OWA）中的会议，例如Office 365，约会的属性是从组织者的原始约会复制而来的，这些属性中包括扩展属性，其中包括AppointId。 因此，为了避免此问题，我们将与会者的约会id设置为与organizer中的原始id相似，只需添加服务所有者（生成通知的服务）的电子邮件地址。 如果没有此解决方案，内部系统中的约会将具有与原始预订类似的AppointmentID，并且将被视为一个约会，或者您可能有两个具有相同ID的不同约会

if（GetGuidFormetingAppoint（预约）.Length谢谢你的代码。我试过了，效果很好。这是否意味着我不能使用约会唯一id来更新、取消约会，因为它会在一段时间后更改？我可以使用此GUID绑定到会议，然后更新、取消它吗？关于唯一id，是的，你可以使用它，但很难跟踪它如果约会被移动到另一个文件夹，例如，如果它被删除，尽管您收到的通知来自同一个约会，但UniqueID将发生变化，因此如果您将UniqueID映射为主键，那么在会议中，同一个约会将有两行，这是不同且棘手的部分Organizer创建会议并将其发送给与会者，实际上它会将同一约会对象的副本发送给与会者。一旦创建了约会，扩展属性（“AppointmentID”）当然将为空，然后将发送给与会者。在这种情况下（在新创建的情况下）这没关系，因为与会者会将约会视为新的约会并放置自己的GUID。但是！一旦组织者更改会议，它将覆盖其余的所有属性，包括我们的“AppointmentID”！！！在OWA（在线Web访问）的情况下，此问题发生在我身上例如，如果您使用的是office 365。我在outlook的“内部部署”版本中没有遇到此问题（我不知道为什么）。无论如何，如果您希望我帮助您解决此问题，请在遇到问题后发表新帖子，我将与您分享我使用的解决方案。这样，更多人可以受益，我可以获得更多分数；）在这里，我使用Guid在exchange约会和内部数据库或内部日历中的约会之间进行映射。但您可以始终使用唯一ID将通知绑定到约会。我在这里的解决方案解决了那些希望将exchange约会与系统中约会同步的人的问题。我已更新了我的回答上面的问题并添加代码。现在这是我这边的解决方案，根据我们的需要，它可能与您需要的方式或您解决它的方式不同。但是看一看，试着理解这个概念，我几乎在每行后面都放了许多注释。
