如何获取Outlook.MeetingItem的发件人ExchangeUser和邮件地址

Question

When users accept/deny a calendar meeting request, and the organiser opens the confirmation/rejection message, the object type of the Inspector.CurrentItem is Outlook.MeetingItem.

MeetingItem does not seem to expose the Sender property. How can I get the Sender.GetExchangeUser() equivalent of a MeetingItem?

Like MailItem, the MeetingItem exposes a SenderEmailType property, which can hold the value "EX", meaning the SenderEmailAddress does not contain the actual email address. Microsoft has nicely documented how to get the sender of a an Outlook.MailItem by usage of the Sender property.

您可以使用MeetingItem.PropertyAccessor.GetProperty检索PR_SENDER_ENTRYID （DASL名称为http://schemas.microsoft.com/mapi/proptag/0x0C190102 ）或PR_SENT_REPRESENTING_ENTRYID （DASL名称为http://schemas.microsoft.com/mapi/proptag/0x00410102 ）。 ，使用PropertyAccessor.BinaryToString将其转换为十六进制字符串，并使用其调用Namespace.GetAddressEntryFromID 。
