如何在VB.NET中使用Outlook.MailItem获取发件人电子邮件地址？

我尝试使用mailItem.SenderEmailAddress和mailItem.Sender.Address,但它们都返回一个如下所示的字符串：

/ O = DOMAINNAME / OU = EXCHANGE ADMINISTRATIVE GROUP(FYDIBOHI43SPCLT)/ CN = RECIPIENTS / CN = JOE BLOGGS8C3

实际上我希望[e-mail]被重新发布.

有人有主意吗？

非常感谢你.

编辑：我做了一些挖掘;它适用于“SenderEmailType”SMTP的电子邮件地址,它只适用于Exchange电子邮件地址.

编辑2：我已经尝试了指定here的代码,但我认为它已经过时了,因为它会抛出“无法创建Active-X组件”错误.

对于任何遇到与我相同问题的人,我找到了答案(在C#中,转换为VB.NET,仍然有效)：

Private Function GetSenderSMTPAddress(mail As Outlook.MailItem) As String
    Dim PR_SMTP_ADDRESS As String = "http://schemas.microsoft.com/mapi/proptag/0x39FE001E"
    If mail Is nothing Then
        Throw New ArgumentNullException()
    End If
    If mail.SenderEmailType = "EX" Then
        Dim sender As Outlook.AddressEntry = mail.Sender
        If sender IsNot nothing Then
            'Now we have an AddressEntry representing the Sender
            If sender.AddressEntryUserType = Outlook.OlAddressEntryUserType.olExchangeUserAddressEntry OrElse sender.AddressEntryUserType = Outlook.OlAddressEntryUserType.olExchangeRemoteUserAddressEntry Then
                'Use the ExchangeUser object PrimarySMTPAddress
                Dim exchUser As Outlook.ExchangeUser = sender.GetExchangeUser()
                If exchUser IsNot nothing Then
                    Return exchUser.PrimarySmtpAddress
                Else
                    Return nothing
                End If
            Else
                Return TryCast(sender.PropertyAccessor.GetProperty(PR_SMTP_ADDRESS),String)
            End If
        Else
            Return nothing
        End If
    Else
        Return mail.SenderEmailAddress
    End If
End Function

我看到你已回答了自己的问题.我会在这里发布我的C#函数,任何人都需要它,或者如果你想用它作为更多的帮助.我做你做的C#函数看起来像这样：

private string getSenderEmailAddress(Outlook.MailItem mail)
{
 Outlook.AddressEntry sender = mail.Sender;
 string SenderEmailAddress = "";

  if (sender.AddressEntryUserType == Outlook.OlAddressEntryUserType.olExchangeUserAddressEntry || sender.AddressEntryUserType == Outlook.OlAddressEntryUserType.olExchangeRemoteUserAddressEntry)
    {
        Outlook.ExchangeUser exchUser = sender.GetExchangeUser();
        if (exchUser != null)
        {
            SenderEmailAddress = exchUser.PrimarySmtpAddress;
        }
    }
    else
    {
        SenderEmailAddress = mail.SenderEmailAddress;
    }

    return SenderEmailAddress;
}
