如何使用EWS JAVA API获得访问另一个邮箱日历的权限

Question

我可以使用以下代码在我的组织中获得可用的会议室，我需要获得特定房间的预约，所以我使用了以下代码

public static void main(String[] args) throws Exception {
    // TODO Auto-generated method stub
    static ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
    ExchangeCredentials credentials = new WebCredentials("[e-mail]", "zzzz");
    service.setCredentials(credentials);
    try {
        System.out.println("Check");
        service.autodiscoverUrl("[e-mail]",new RedirectionUrlCallback());



    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    NameResolutionCollection nameResolutions = service.resolveName("MeetingRoom1",ResolveNameSearchLocation.DirectoryOnly, true);
    System.out.println("nameResolutions==="+nameResolutions.getCount());

    for(NameResolution nameResolution : nameResolutions)
    {
        System.out.println("NAME==="+nameResolution.getContact().getDisplayName());


    }
    Date startDate = new Date();
    Calendar cal = Calendar.getInstance();
    cal.setTime(startDate);
    cal.add(Calendar.DATE, 30); // add 10 days

    Date endDate = cal.getTime();
       Mailbox meetingMailbox = new Mailbox("[e-mail]");
       FolderId CalendarId = new FolderId(WellKnownFolderName.Calendar, meetingMailbox);
       CalendarView cView = new CalendarView(startDate, endDate);
       FindItemsResults<Appointment> appointments = service.findAppointments(CalendarId, cView);
       for (Appointment a : appointments)
       {
           System.out.println("Subject: " + a.getSubject().toString() + " ");
           System.out.println("Start: " + a.getStart().toString() + " ");
           System.out.println("End: " + a.getEnd().toString());
           System.out.println();
       }
}`

如果我执行此代码，我能够获取组织中所有可用会议室的列表，名称为 MeetingRoom1，然后我正在尝试访问特定 [e-mail] 以获取该房间的约会，但抛出一些异常如下所示。

Exception in thread "main" microsoft.exchange.webservices.data.ServiceResponseException: The specified folder could not be found in the store.
at microsoft.exchange.webservices.data.ServiceResponse.internalThrowIfNecessary(ServiceResponse.java:262)
at microsoft.exchange.webservices.data.ServiceResponse.throwIfNecessary(ServiceResponse.java:251)
at microsoft.exchange.webservices.data.MultiResponseServiceRequest.execute(MultiResponseServiceRequest.java:146)

at microsoft.exchange.webservices.data.ExchangeService.findAppointments(ExchangeService.java:1089)
at com.hcl.GetRoomClass.main(GetRoomClass.java:58)

我想这可能是因为我没有访问会议室日历的权限。如何进一步获得预约。请帮我。我需要EWS-JAVA API。

提前谢谢。

您的代码运行的帐户需要委托访问会议室的日历才能使该代码工作。这是您的管理员需要在服务器上为您配置的内容。
