我使用ews-javascript-api来管理我的交换联系人。我可以创建一个联系人并添加一个给定名称和姓氏，但我尝试添加电子邮件地址或电话号码的所有内容都会导致异常被抛出。这就是我现在正在尝试的。
let number = {type: 2, value: "1234567890"};
let newContact = new ews.Contact(window.exchangeService);
newContact.PhoneNumbers.entries.Add(number.type, number.value);
let address = {type: 0, value: "test@test.org"};
newContact.EmailAddresses.entries.Add(address.type, address.value);
我得到的例外......

设置这些项目的正确方法是contact.EmailAddresses._setItem(ews.EmailAddressKey.EmailAddress1, emailEntry1);
