发送邀请时，它需要用户接受，当用户接受邀请时，Outlook日历将状态显示为忙
有什么方法可以发送不需要用户接受邀请并且Outlook日历显示为不在办公室"的邀请?
我已经尝试过这两个部分，但没有运气
when the invitation is send, it need the user to accept the invitation, and when the user accept the invitation, Outlook calendar shows the status as BUSY
is there any way to send the invitation that does not require user to accept it and the Outlook calendar shows as Out Of Office ?
i have tried with this 2 part but no luck
str.AppendLine("ACTION:Accept");
str.AppendLine("X-MICROSOFT-CDO-BUSYSTATUS:BUSY");
推荐答案
如果这是资源邮箱，则可以将其配置为自动接受会议邀请(文件|选项|日历|自动接受或拒绝).
If this is a resource mailbox, you can configure it to auto accept meeting invitations (File | Options | Calendar | Automatic Accept or Decline).
如果这是一个任意邮箱，那么在没有所有者允许的情况下不会发生任何事情.如果您有用户凭据，则最好的办法是使用Outlook对象模型/EWS/MAPI直接访问邮箱.
If this is an arbitrary mailbox, nothing happens without the owner's permission. The best you can do is directly access the mailbox using the Outlook Object Model / EWS/ MAPI if you have the user credentials.
