EWS除去必需的与会者时，发出邀请函给大家 [英] EWS sends invitations to everyone when removing a required attendee

问题描述

我有以下代码：

（会议beeing交流预约）

(Meeting beeing the exchange appointment)

For Each Recipient As String In emailAdresses 
    For i As Integer = 0 To Meeting.RequiredAttendees.Count - 1
        If (Meeting.RequiredAttendees(i).Address).ToUpper() = Recipient.ToUpper() Then
            Meeting.RequiredAttendees.RemoveAt(i)
            Exit For
        End If
    Next
Next

Meeting.Update(ConflictResolutionMode.AutoResolve, SendInvitationsOrCancellationsMode.SendOnlyToChanged)

现在，你可以看到我使用SendInvitationsOrCancellationsMode。 SendOnlyToChanged。

Now as you can see i'm using SendInvitationsOrCancellationsMode.SendOnlyToChanged.

但是，即使我使用此模式下，仍然是发送预约所有与会者的。

But even though that i'm using that mode it is still sending the appointment to all of the attendees.

我看了 MSDN 和代码是完全一样的。和MSDN告诉我下面应该发生：

I've looked at msdn and the code is exactly the same. And msdn tells me the following should happen:

保存会议并发送会议取消消息，已删除的与会者或与会者

Save the meeting and send a meeting cancellation message to the attendee or attendees that you removed

所以基本上MSDN最高审计机关它的作品，但事实并非如此。有一个变通此问题或其他任何人遇到同样的问题？

So basically msdn sais it is works but it does not. Is there a work around for this issue or is anyone else experiencing the same problem?

我们的Exchange服务器2007 SP1版本。

our exchange server is a 2007 SP1 version.

答案可以在C＃或VB.NET中，我将它翻译成我们所需要的语言。

The answer can be in C# or VB.NET, I'll translate it to the language we need.

PS。添加成员和使用这种模式会导致邀请发送到只新添加的成员。但正如我以前说过删除不具有此相同的行为。

PS. Adding members and using this mode causes the invite to send to the newly added member only. But as I said before deleting does not have this same behaviour.

推荐答案

这样做的：

Meeting.Update(ConflictResolutionMode.NeverOverwrite, SendInvitationsOrCancellationsMode.SendOnlyToChanged)

而不是：

Meeting.Update(ConflictResolutionMode.AutoResolve, SendInvitationsOrCancellationsMode.SendOnlyToChanged)

解决我的问题，我不知道为什么，什么它具有虽然麻烦了。

Solved my problem, I do not know why and what it was having trouble with though.
