EWS C＃国际字符在电子邮件地址返回错误

Question

当电子邮件地址包含外来字符时，我在使用EWS将电子邮件地址保存到联系人时遇到问题。特别是，德国变形金刚给了我一些问题。以下是尝试创建有效电子邮件地址的示例。 EWS返回错误，指出电子邮件地址无效。有人可以帮忙吗？感谢

Mailbox mailbox = new Mailbox("box@blah.com");
FolderId folderId = new FolderId(WellKnownFolderName.Contacts, mailbox);
Contact contact = new Contact(service);
contact.GivenName = "John";
contact.Surname = "Döe";

EmailAddress address = new EmailAddress();
address.Address = "JohnDöe@blah.com";
address.RoutingType = "SMTP";

contact.EmailAddresses[EmailAddressKey.EmailAddress1] = address;
contact.Save(folderId);

Answer 1

Exchange是否允许电子邮件地址中的变音符号？

电子邮件地址的管理规范

RFC 5321不允许这样做。有关详细信息，请参阅this SO question on allowed email address characters。
