如何使用EWS托管API从Microsoft Exchange检索所有联系人? [英] How to retrieve all contacts from Microsoft Exchange using EWS Managed API?
问题描述
我要做的就是从Microsoft Exchange检索所有联系人.我做了一些研究，对我来说最好的选择应该是使用EWS托管API.我正在使用Visual Studio和C#编程leanguage.
all I need to do is to retrieve all contacts from Microsoft Exchange. I did some research and the best possible option for me should be to use EWS Managed API. I am using Visual Studio and C# programming leanguage.
我认为我能够连接到Office365帐户，因为我能够将程序中的消息发送到特定的电子邮件.但是我无法检索联系人.
I think I am able to connect to Office365 account, because I am able to send a message in a program to specific email. But I am not able to retrieve the contacts.
如果我直接在源代码中创建联系人，则该联系人将在Office365-> People aplication中创建.但是我不知道为什么！我以为我正在使用Exchange应用程序.
If I create a contact directly in source code, the contact will be created in Office365->People aplication. But I don't know why! I thought I was working with Exchange aplication.
总结: 是否有可能如何从Office365-> Admin-> Exchange-> Acceptencers-> 联系人获取所有联系人?
Summarize: Is there any possibility how to get all contacts from Office365->Admin->Exchange->Acceptencers->Contacts ?
这是我的代码:

/*
// debugging
service.TraceEnabled = true;
service.TraceFlags = TraceFlags.All;
*/
service.AutodiscoverUrl("office365email@test.com", RedirectionUrlValidationCallback);
// send a message works good
EmailMessage email = new EmailMessage(service);
email.ToRecipients.Add("matoskok1@gmail.com");
email.Subject = "HelloWorld";
email.Body = new MessageBody("Toto je testovaci mail");
email.Send();
// Create the contact creates a contact in Office365 -> People application..Don't know why there and not in Office365 -> Exchange

How to retrieve all contacts from Microsoft Exchange using EWS Managed API?
如果您的问题是如何使用EWS检索Exchange联系人，那么您已经完成了.
If your question is how to retrieve the Exchange Contacts using EWS, you're already done with it.
Office365-> People就是处理您的Exchange联系人的正确应用程序.如果您签出People应用程序URL，则类似于 https://outlook.office365.com/owa/?realm=xxxxxx#exsvurl=1&ll-cc=1033&modurl=2 ，owa是Outlook Web App的同义词.
Office365->People is just the right app to manipulate your Exchange contacts. If you check out the People app URL, it's something similar to https://outlook.office365.com/owa/?realm=xxxxxx#exsvurl=1&ll-cc=1033&modurl=2, owa is the synonym for outlook web app.
