Question

我正在尝试使用Exchange Web服务访问组邮箱。

已设置具有对组邮箱的完全访问权限的域帐户，但我收到以下错误：

When making a request as an account that does not have a mailbox, you must specify the mailbox primary SMTP address for any distinguished folder Ids.

我的代码如下：

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013);

service.UseDefaultCredentials = false;
service.Credentials = new WebCredentials("ServiceAccount", "<PASSWORD>");

//find web service url
service.AutodiscoverUrl("<GROUP MAILBOX EMAIL ADDRESS>", RedirectionUrlValidationCallback);

//find calendar ID
FolderId folderID = new FolderId(WellKnownFolderName.Calendar, new Mailbox("<GROUP MAILBOX EMAIL ADDRESS>"));

//find calendar
CalendarFolder calendar = CalendarFolder.Bind(service, folderID);

//create CalendarView
CalendarView view = null;

var propertySet = new PropertySet(
    AppointmentSchema.Id,
    AppointmentSchema.Subject,
    AppointmentSchema.Start,
    AppointmentSchema.End
);

view = new CalendarView(DateTime.Now.AddMonths(-1), DateTime.Now.AddMonths(1));
view.PropertySet = propertySet;

//get appointments
var appointments = calendar.FindAppointments(view);

如果没有为服务帐户设置邮箱，有没有办法实现这一目标？

当我使用我的凭据运行上述代码时，没有问题（我拥有组邮箱的完全权限，以及我自己的邮箱）。

使用impersonation。此代码非常适合我作为服务帐户连接到共享邮箱。

ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2013_SP1);
service.Credentials = new NetworkCredential(service_acct, password);

// Set impersonation to the shared mailbox
service.ImpersonatedUserId = new ImpersonatedUserId(ConnectingIdType.SmtpAddress, "sharedmbx@contoso.com");
