我需要为每个约会保存一个指导。我尝试使用PolicyTagand ArchiveTag，但得到了 ,
"属性 PolicyTag 仅对 Exchange Exchange2013 或更高版本有效。",
例外。
Exchange 2010 有类似的东西吗？据我了解appointment.ID，其中包含自生成的 id。我宁愿不使用它。谢谢你。

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中复制它，否则它不会改变（毕竟它只是一个属性）
private static readonly PropertyDefinitionBase AppointementIdPropertyDefinition = new ExtendedPropertyDefinition(DefaultExtendedPropertySet.PublicStrings, "AppointmentID", MapiPropertyType.String);
public static PropertySet PropertySet = new PropertySet(BasePropertySet.FirstClassProperties, AppointementIdPropertyDefinition);
//Setting the property for the appointment
public static void SetGuidForAppointement(Appointment appointment)
{
try
{
appointment.SetExtendedProperty((ExtendedPropertyDefinition)AppointementIdPropertyDefinition, Guid.NewGuid().ToString());
appointment.Update(ConflictResolutionMode.AlwaysOverwrite, SendInvitationsOrCancellationsMode.SendToNone);
}
catch (Exception ex)
{
// logging the exception
}
}
//Getting the property for the appointment
public static string GetGuidForAppointement(Appointment appointment)
{
var result = "";
try
{
appointment.Load(PropertySet);
foreach (var extendedProperty in appointment.ExtendedProperties)
{
if (extendedProperty.PropertyDefinition.Name == "AppointmentID")
{
result = extendedProperty.Value.ToString();
}
}
}
catch (Exception ex)
{
// logging the exception
}
return result;
}
此解决方案在单个约会和使用 On Premises Exchange 的情况下非常有效。这里的问题是在线 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中复制的，这些属性中有 AppoinmentID 是其中的扩展属性. 因此，为了避免这种麻烦，我们在组织者中将参加者的约会 id 设置为与原始的相似，并添加服务所有者（产生通知的服务）的电子邮件地址。如果没有这个解决方案，内部系统中的约会将具有与原始预订相似的 AppointmentID 并被视为一个，或者您可能有两个具有相同 ID 的不同约会。
private static void SetGuidForMeetingAppiontment(Appointment appointment)
{
var log = "";
try
{
if (!appointment.IsMeeting) return;
if (appointment.Service.ImpersonatedUserId == null) return;
/*
* The only tricky case is that if the appointment is created at the attendee with no Guid.
* In this case the application should look for the original appointment from the organizer's side, and get its guid, to paste it in the new booking
* from the attendee side, and add the attendee emailAddress.
