运行交换 2013
我在 C# 服务中使用 EWS,该服务从服务帐户发送电子邮件。
我想让电子邮件有一个与发送帐户不同的回复地址,即通讯组列表地址。
我怎样才能做到这一点?这EmailMessage.ReplyTo
字段是只读的。
Code:
ExchangeService service = new ExchangeService();
service.Credentials = EWScredentials;
service.Url = new Uri(string.Format("https://{0}/EWS/Exchange.asmx", ExchangePath));
EmailMessage message = new EmailMessage(service);
message.ToRecipients.AddRange(receipients);
//This didn't work
message.ReplyTo.Clear();
message.ReplyTo.Add(replyToAddress);
message.Subject = subject;
message.Body = html;
message.SendAndSaveCopy();
尽管我没有使用 powershell,但只有其他似乎相关的线程:如何使用 EWS 托管 API 设置消息回复地址?
您可以使用 PidTagReplyRecipientEntries 扩展属性https://msdn.microsoft.com/en-us/library/office/cc815710.aspx这样做例如
EmailMessage DifferentReplyTo = new EmailMessage(service);
DifferentReplyTo.Subject = "test";
DifferentReplyTo.ToRecipients.Add("[email protected]");
DifferentReplyTo.Body = new MessageBody("test");
ExtendedPropertyDefinition PidTagReplyRecipientEntries = new ExtendedPropertyDefinition(0x004F, MapiPropertyType.Binary);
ExtendedPropertyDefinition PidTagReplyRecipientNames = new ExtendedPropertyDefinition(0x0050, MapiPropertyType.String);
DifferentReplyTo.SetExtendedProperty(PidTagReplyRecipientEntries, ConvertHexStringToByteArray(GenerateFlatList("[email protected]", "jc")));
DifferentReplyTo.SetExtendedProperty(PidTagReplyRecipientNames, "jc");
DifferentReplyTo.SendAndSaveCopy();
internal static String GenerateFlatList(String SMTPAddress, String DisplayName)
{
String abCount = "01000000";
String AddressId = GenerateOneOff(SMTPAddress, DisplayName);
return abCount + BitConverter.ToString(INT2LE((AddressId.Length / 2) + 4)).Replace("-", "") + BitConverter.ToString(INT2LE(AddressId.Length / 2)).Replace("-", "") + AddressId;
}
internal static String GenerateOneOff(String SMTPAddress,String DisplayName)
{
String Flags = "00000000";
String ProviderUid = "812B1FA4BEA310199D6E00DD010F5402";
String Version = "0000";
String xFlags = "0190";
String DisplayNameHex = BitConverter.ToString(UnicodeEncoding.Unicode.GetBytes(DisplayName + "\0")).Replace("-","");
String SMTPAddressHex = BitConverter.ToString(UnicodeEncoding.Unicode.GetBytes(SMTPAddress + "\0")).Replace("-", "");
String AddressType = BitConverter.ToString(UnicodeEncoding.Unicode.GetBytes("SMTP" + "\0")).Replace("-", "");
return Flags + ProviderUid + Version + xFlags + DisplayNameHex + AddressType + SMTPAddressHex;
}
internal static byte[] INT2LE(int data)
{
byte[] b = new byte[4];
b[0] = (byte)data;
b[1] = (byte)(((uint)data >> 8) & 0xFF);
b[2] = (byte)(((uint)data >> 16) & 0xFF);
b[3] = (byte)(((uint)data >> 24) & 0xFF);
return b;
}
internal static byte[] ConvertHexStringToByteArray(string hexString)
{
if (hexString.Length % 2 != 0)
{
throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number of digits: {0}", hexString));
}
byte[] HexAsBytes = new byte[hexString.Length / 2];
for (int index = 0; index < HexAsBytes.Length; index++)
{
string byteValue = hexString.Substring(index * 2, 2);
HexAsBytes[index] = byte.Parse(byteValue, NumberStyles.HexNumber, CultureInfo.InvariantCulture);
}
return HexAsBytes;
}
干杯
