我需要做的就是从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 Managed API。我正在使用Visual Studio和C＃编程leanguage。
我认为我可以连接到Office365帐户，因为我可以将程序中的消息发送到特定的电子邮件。但我无法检索联系人。
如果我直接在源代码中创建联系人，则会在Office365-＆gt;人员应用程序中创建联系人。但我不知道为什么！我以为我正在使用Exchange应用程序。
概述： 是否有可能如何从Office365-＆gt; Admin-＆gt; Exchange-＆gt; Acceptencers-＆gt; 联系人获取所有联系人？
这是我的代码：
class Program
{
static void Main(string[] args)
{
// connecting to my Exchange account
ServicePointManager.ServerCertificateValidationCallback = CertificateValidationCallBack;
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2007_SP1);
service.Credentials = new WebCredentials("office365email@test.com", "password123");
/*
// 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
/*Contact contact = new Contact(service);
// Specify the name and how the contact should be filed.
contact.GivenName = "Brian";
contact.MiddleName = "David";
contact.Surname = "Johnson";
contact.FileAsMapping = FileAsMapping.SurnameCommaGivenName;
// Specify the company name.
contact.CompanyName = "Contoso";
// Specify the business, home, and car phone numbers.
contact.PhoneNumbers[PhoneNumberKey.BusinessPhone] = "425-555-0110";
contact.PhoneNumbers[PhoneNumberKey.HomePhone] = "425-555-0120";
contact.PhoneNumbers[PhoneNumberKey.CarPhone] = "425-555-0130";
// Specify two email addresses.
contact.EmailAddresses[EmailAddressKey.EmailAddress1] = new EmailAddress("brian_1@contoso.com");
contact.EmailAddresses[EmailAddressKey.EmailAddress2] = new EmailAddress("brian_2@contoso.com");
// Specify two IM addresses.
contact.ImAddresses[ImAddressKey.ImAddress1] = "brianIM1@contoso.com";
contact.ImAddresses[ImAddressKey.ImAddress2] = " brianIM2@contoso.com";
// Specify the home address.
PhysicalAddressEntry paEntry1 = new PhysicalAddressEntry();
paEntry1.Street = "123 Main Street";
paEntry1.City = "Seattle";
paEntry1.State = "WA";
paEntry1.PostalCode = "11111";
paEntry1.CountryOrRegion = "United States";
contact.PhysicalAddresses[PhysicalAddressKey.Home] = paEntry1;
// Specify the business address.
PhysicalAddressEntry paEntry2 = new PhysicalAddressEntry();
paEntry2.Street = "456 Corp Avenue";
paEntry2.City = "Seattle";
paEntry2.State = "WA";
paEntry2.PostalCode = "11111";
paEntry2.CountryOrRegion = "United States";
contact.PhysicalAddresses[PhysicalAddressKey.Business] = paEntry2;
// Save the contact.
contact.Save();
*/
// msdn.microsoft.com/en-us/library/office/jj220498(v=exchg.80).aspx
// Get the number of items in the Contacts folder.
ContactsFolder contactsfolder = ContactsFolder.Bind(service, WellKnownFolderName.Contacts);
Console.WriteLine(contactsfolder.TotalCount);
// Set the number of items to the number of items in the Contacts folder or 50, whichever is smaller.
int numItems = contactsfolder.TotalCount < 50 ? contactsfolder.TotalCount : 50;
// Instantiate the item view with the number of items to retrieve from the Contacts folder.
ItemView view = new ItemView(numItems);
// To keep the request smaller, request only the display name property.
view.PropertySet = new PropertySet(BasePropertySet.IdOnly, ContactSchema.DisplayName);
// Retrieve the items in the Contacts folder that have the properties that you selected.
FindItemsResults<Item> contactItems = service.FindItems(WellKnownFolderName.Contacts, view);

看起来你已经在做一个FindItems（）方法做得很好。
为了获得所有你需要添加的联系人是SearchFilter，在这种情况下我建议你做Exists（）过滤器，因为你可以简单地说找到一个带有id的所有联系人。
如果您需要一个处理联系人的完整Windows应用程序示例，请参阅下面的示例，请参阅我的github页面github.com/rojobo
Dim oFilter As New SearchFilter.Exists(ItemSchema.Id)
Dim oResults As FindItemsResults(Of Item) = Nothing
Dim oContact As Contact
Dim blnMoreAvailable As Boolean = True
Dim intSearchOffset As Integer = 0
Dim oView As New ItemView(conMaxChangesReturned, intSearchOffset, OffsetBasePoint.Beginning)
oView.PropertySet = BasePropertySet.IdOnly
Do While blnMoreAvailable
oResults = pService.FindItems(WellKnownFolderName.Contacts, oFilter, oView)
blnMoreAvailable = oResults.MoreAvailable
If Not IsNothing(oResults) AndAlso oResults.Items.Count > 0 Then
For Each oExchangeItem As Item In oResults.Items
Dim oExchangeContactId As ItemId = oExchangeItem.Id
//do something else
Next
If blnMoreAvailable Then oView.Offset = oView.Offset + conMaxChangesReturned
End If
Loop

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，那么您已经完成了它。
Office365-＆gt;人们是操作Exchange联系人的合适应用。如果您查看人员应用网址，则类似于https://outlook.office365.com/owa/?realm=xxxxxx#exsvurl=1&ll-cc=1033&modurl=2，owa是Outlook网络应用的同义词。
