UpdateDelegateType class

The UpdateDelegateType class represents a request to update delegate settings on a mailbox.

Namespace:  ExchangeWebServices
Assembly:  EWS (in EWS.dll)

public class UpdateDelegateType : BaseDelegateType

The following example shows you how to update delegate permissions on user1's account. User2 is granted the None permission level for the Calendar folder and is granted permission to view private items. User3 is granted Reviewer permissions for the Journal folder. Meeting requests are sent to the delegates and information about the request is sent to user1.

static void UpdateDelegate()
    // Set the version, credentials, and the Client Access server on ExchangeServiceBinding.
    ExchangeServiceBinding esb = new ExchangeServiceBinding();
    esb.RequestServerVersionValue = new RequestServerVersion();
    esb.RequestServerVersionValue.Version = ExchangeVersionType.Exchange2007_SP1;
    esb.Credentials = new NetworkCredential("username", "password", "domain");
    esb.Url = "https://FQDN/ews/exchange.asmx";

    // Create the request.
    UpdateDelegateType request = new UpdateDelegateType();

    // Identify the mailbox for which delegate settings will be updated.
    request.Mailbox = new EmailAddressType();
    request.Mailbox.EmailAddress = "user1@example.com";

    // Update delegate user permissions for user2.
    request.DelegateUsers = new DelegateUserType[3] { new DelegateUserType(), new DelegateUserType(), new DelegateUserType() };
    request.DelegateUsers[0].UserId = new UserIdType();
    request.DelegateUsers[0].UserId.PrimarySmtpAddress = "user2@example.com";
    request.DelegateUsers[0].DelegatePermissions = new DelegatePermissionsType();
    request.DelegateUsers[0].DelegatePermissions.CalendarFolderPermissionLevel = DelegateFolderPermissionLevelType.None;
    request.DelegateUsers[0].DelegatePermissions.CalendarFolderPermissionLevelSpecified = true;
    request.DelegateUsers[0].ViewPrivateItems = true;
    request.DelegateUsers[0].ViewPrivateItemsSpecified = true;

    // Update delegate user permissions.
    request.DelegateUsers[1].UserId = new UserIdType();
    request.DelegateUsers[1].UserId.PrimarySmtpAddress = "user3@example.com";
    request.DelegateUsers[1].DelegatePermissions = new DelegatePermissionsType();
    request.DelegateUsers[1].DelegatePermissions.JournalFolderPermissionLevel = DelegateFolderPermissionLevelType.Reviewer;
    request.DelegateUsers[1].DelegatePermissions.JournalFolderPermissionLevelSpecified = true;

    // Identify how meeting requests are handled.
    request.DeliverMeetingRequests = new DeliverMeetingRequestsType();
    request.DeliverMeetingRequests = DeliverMeetingRequestsType.DelegatesAndSendInformationToMe;
    request.DeliverMeetingRequestsSpecified = true;

        // Send the UpdateDelegate request and get the response.
        UpdateDelegateResponseMessageType response = esb.UpdateDelegate(request);
        DelegateUserResponseMessageType[] durmt = new DelegateUserResponseMessageType[] { };
        durmt = response.ResponseMessages;

        // Check each response message.
        foreach (DelegateUserResponseMessageType resp in durmt)
            if (resp.ResponseClass == ResponseClassType.Success)
                Console.WriteLine("Delegate user updated: " + resp.DelegateUser.UserId.DisplayName);
            else if (resp.ResponseClass == ResponseClassType.Error)
                Console.WriteLine("Error: " + resp.MessageText);
                Console.WriteLine("Warning: " + resp.MessageText);
    catch (Exception e)
