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joebloggs@domainname.co.uk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.
编辑3：
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;
}
