EWS C＃國際字符在電子郵件地址返回錯誤

Question

我遇到問題使用EWS將電子郵件地址保存到聯繫人，當電子郵件地址包含外部字符。特別是，德國的變音是給我的問題。以下是嘗試創建有效電子郵件地址的示例。 EWS拋出一個錯誤，指出電子郵件地址無效。任何人都可以幫忙嗎？謝謝

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是否允許在電子郵件地址中出現變音符號？

RFC 5321，電子郵件地址的治理規範，不允許他們。有關更多信息，請參閱this SO question on allowed email address characters。
