日历委派是Exchange的一项功能,Graph API和Outlook API不允许用户访问委派的日历.

目前,替代解决方法可以使用EWS.以下是供您参考的示例：

static void DelegateAccessSearchWithFilter(ExchangeService service, SearchFilter filter)

{

// Limit the result set to 10 items.

ItemView view = new ItemView(10);

view.PropertySet = new PropertySet(ItemSchema.Subject,

ItemSchema.DateTimeReceived,

EmailMessageSchema.IsRead);

// Item searches do not support deep traversal.

view.Traversal = ItemTraversal.Shallow;

// Define the sort order.

view.OrderBy.Add(ItemSchema.DateTimeReceived, SortDirection.Descending);

try

{

// Call FindItems to find matching calendar items.

// The FindItems parameters must denote the mailbox owner,

// mailbox, and Calendar folder.

// This method call results in a FindItem call to EWS.

FindItemsResults results = service.FindItems(

new FolderId(WellKnownFolderName.Calendar,

"fx@msdnofficedev.onmicrosoft.com"),

filter,

view);

foreach (Item item in results.Items)

{

Console.WriteLine("Subject: {0}", item.Subject);

Console.WriteLine("Id: {0}", item.Id.ToString());

}

}

catch (Exception ex)

{

Console.WriteLine("Exception while enumerating results: { 0}", ex.Message);

}

}

private static void GetDeligateCalendar(string mailAddress, string password)

{

ExchangeService service = new ExchangeService();

service.Credentials = new WebCredentials(mailAddress, password);

service.TraceEnabled = true;

service.TraceFlags = TraceFlags.All;

service.AutodiscoverUrl(mailAddress, RedirectionUrlValidationCallback);

SearchFilter sf = new SearchFilter.SearchFilterCollection(LogicalOperator.And, new SearchFilter.IsEqualTo(AppointmentSchema.Subject, "Discuss the Calendar REST API"));

DelegateAccessSearchWithFilter(service, sf);

}
