Answer 1

我刚刚在错误消息中按此行，因为您还没有发布您的代码：

  

EWS_Mail_Object_New.New_Mail1（String UserName，String Password，String MailID，String Service_URL，String recipient，String Subject，   String message_body，String cc，Boolean SaveAsDraft，DataTable   附件，DataTable Inline_Attachments，String bcc，Boolean＆amp;   成功，弦乐＆amp;消息）

错误表示未设置电子邮件地址.E它是一个空字符串。 调试并检查recipient，cc和bcc是否设置了电子邮件地址。
