vba - 获取发件人电子邮件地址

Question

我有以下 VBA 代码，用于在收到特定主题时发送自动电子邮件。

Private WithEvents Items As Outlook.Items

Private Sub Application_Startup()
Dim objNS As Outlook.NameSpace
Set objNS = GetNamespace("MAPI")
Set Items = objNS.GetDefaultFolder(olFolderInbox).Items
End Sub

Private Sub Items_ItemAdd(ByVal item As Object)
If item.Class = olMail Then
    If Left$(item.Subject, 29) = "Hazard Identification Report" Then
        Dim Msg As Outlook.MailItem
        Dim NewForward As Outlook.MailItem
        Dim myFolder As Outlook.MAPIFolder
        Dim olApp As Outlook.Application
        Dim olNS As Outlook.NameSpace

        Set Msg = item
        Set NewForward = Msg.Forward
        Set olApp = Outlook.Application
        Set olNS = olApp.GetNamespace("MAPI")

        strSender = ""
        strSenderName = Sender.GetExchangeUser().PrimarySmtpAddress

        If itm.SenderEmailAddress = "EX" Then
            Set objSender = itm.Sender
            If Not (objSender Is Nothing) Then
                Set objExchUser = Sender.GetExchangeUser()
                If Not (objExchUser Is Nothing) Then
                    strSender = objExchUser.PrimarySmtpAddress
                End If
            End If
        Else
            strSender = itm.SenderEmailAddress
        End If

我在以下行收到编译/对象错误：

strSenderName = Sender.GetExchangeUser().PrimarySmtpAddress

发件人姓名显示为“空”。

如何提取发件人的电子邮件地址？

Answer 1

最初在评论中回答。

为什么不是 msg.SenderEmailAddress

Answer 2

以上接受的答案对我不起作用。相反，我正在使用它（也适用于 MeetingItems）：

Function GetSenderEmail(oM As Variant)

   Dim oPA As Outlook.PropertyAccessor
   Set oPA = oM.PropertyAccessor

   GetSenderEmail = oPA.GetProperty("http://schemas.microsoft.com/mapi/proptag/0x5D01001E")

End Function
