EWS C＃国际字符在电子邮件地址返回错误

Question

我遇到问题使用EWS将电子邮件地址保存到联系人，当电子邮件地址包含外部字符。特别是，德国的变音是给我的问题。以下是尝试创建有效电子邮件地址的示例。 EWS抛出一个错误，指出电子邮件地址无效。任何人都可以帮忙吗？谢谢

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是否允许在电子邮件地址中出现变音符号？

RFC 5321，电子邮件地址的治理规范，不允许他们。有关更多信息，请参阅this SO question on allowed email address characters。
