如何使用EWS托管API访问共享日历

Question

如何知道使用Exchange EWS API共享了哪个日历。

Answer 1

您可以只指定要在folderid中访问的日历。

FolderId folderIdFromCalendar = new FolderId(WellKnownFolderName.Calendar, "[e-mail]");

然后，您可以使用FolderIdFromCalendar检索您想要的日历项目，例如：

FindItemsResults<Item> appointments = ExchangeServive.FindItems(folderIdFromCalendar, ItemView);

请记住，程序必须在共享邮箱的用户上下文中运行。

FolderId folderIdFromCalendar = new FolderId("AQMkADAwATM3ZmYAZS1kNjE0LWU1ZmQtMDACLTAwCgAuAAADJRMtiupYBUGD‌​cKdcqUrr3AEA1/sqwbrw‌​UEeFM0Mc+UBFoQAAABzk‌​m1sAAAA=");

if (folderIdFromCalendar != null)
    {
        try
        {
            ItemView cView = new ItemView(1000);
            FindItemsResults<Item> appointments = service.FindItems(folderIdFromCalendar, cView);
            int count = appointments.TotalCount; //just an example of some random action on the folder calendar
        }
        catch (ServiceResponseException ex)
        {
            Console.WriteLine("The specified calendar was not shared with you. \n" + ex);
        }
    }
    else
    {
        Console.WriteLine("The specified calendar ID could not be linked to a calendar folder.");
    }

if (folderIdFromCalendar != null)
    {
        if (folderIdFromCalendar.Mailbox.ToString().ToLower() == "your-Mailadress".ToLower())
        {
            Console.WriteLine("The folder you specified is your own");
        }
        else
        {
            try
            {
                ItemView cView = new ItemView(1000);
                FindItemsResults<Item> appointments = service.FindItems(folderIdFromCalendar, cView);
                int count = appointments.TotalCount; //just an example of some random action on the folder calendar
                Console.WriteLine("You have been given access to this mailbox. Its owner is: " + folderIdFromCalendar.Mailbox.ToString()); //if you need to know, whos mailbox you are accessing right now
            }

    Folder folderFromCalendar = Folder.Bind(service, folderIdFromCalendar);

    AlternateId aiAlternateid = new AlternateId(IdFormat.EwsId, folderFromCalendar.Id.UniqueId, "[e-mail]");
    AlternateIdBase aiResponse = service.ConvertId(aiAlternateid, IdFormat.EwsId);

    var mailbox = ((AlternateId)aiResponse).Mailbox;

    if (folderFromCalendar != null)
