我有一个收件箱设置作为交换,hello @ mycompany.com
此外,还有一个别名,news @ mycompany.com,因此所有发送到新闻地址的电子邮件都会在hello收件箱中结束.
理想情况下,我希望能够使用EWS告知发送电子邮件的别名.
当我向news@mycompany.com发送电子邮件,并使用Microsoft Outlook检查邮件的Internet标头时,To：标头读取To：Hello< news@mycompany.com\u0026gt;这正是我想要看到的. 但是,使用EWS时,当我查看邮件的ToRecipients属性时,报告的电子邮件地址始终是主SMTP地址的电子邮件地址.此外,Webservices.Data.Item的InternetMessageHeaders属性不包含To：属性.我似乎也无法使用EWSEditor查看正确的地址来检查消息的所有属性.
this forum post的答案似乎表明,
…The Information about the actual email address a message is sent to is stored in the recipients collection which you can’t access (outside of exportmessage) in EWS…
我将如何以编程方式执行此操作,以便找到正确的To：地址？
解决方法
这对我有用：
private static string GetToAddress()
{
ExchangeService exService = new ExchangeService();
exService.Credentials = new NetworkCredential("username","password","domain");
exService.Url = new Uri("https://youraddress/EWS/Exchange.asmx");
ExtendedPropertyDefinition PR_TRANSPORT_MESSAGE_HEADERS = new ExtendedPropertyDefinition(0x007D,MapiPropertyType.String);
PropertySet psPropSet = new PropertySet(BasePropertySet.FirstClassProperties)
{PR_TRANSPORT_MESSAGE_HEADERS,ItemSchema.MimeContent};
FindItemsResults<Item> fiResults = exService.FindItems(WellKnownFolderName.InBox,new ItemView(1));
foreach (Item itItem in fiResults.Items)
{
itItem.Load(psPropSet);
Object valHeaders;
if (itItem.TryGetProperty(PR_TRANSPORT_MESSAGE_HEADERS,out valHeaders))
{
Regex regex = new Regex(@"To:.*<(.+)>");
Match match = regex.Match(valHeaders.ToString());
if (match.Groups.Count == 2)
return match.Groups[1].Value;
}
return ToAddress;
}
return "Cannot find ToAddress";
}@H_301_21@
