Artículos de búsqueda de servicios web de Exchange(EWS) en todas las carpetas

Question

Estoy utilizando el siguiente código para encontrar todos los correos electrónicos enviados por un usuario, sin embargo, esto solo busca en la carpeta principal de la Bandeja de entrada y no revisa ninguna subcarpeta. Me gustaría buscar todos los elementos de correo, incluidas las subcarpetas.

He probado el WellKnownFolderName.Root y el WellKnownFolderName.Inbox y estos solo buscan esas carpetas, no las subcarpetas.

 private static void SearchItems(string email)
{
ItemView iv = new ItemView(10);
FindItemsResults<Item> fiitems = _service.FindItems(WellKnownFolderName.Inbox, "from:[email protected]", iv);
foreach (Item item in fiitems)
{
Console.WriteLine("Subject:/t" + item.Subject);
Console.WriteLine("Received At:/t/t" + item.DateTimeReceived.ToString("dd MMMM yyyy"));
Console.WriteLine();
}
Console.WriteLine("Press Enter to continue");
Console.ReadLine();
}

He encontrado información en la carpeta AllItems dentro de Exchange en el blog de Glen http://gsexdev.blogspot.com/2011/08/using-allitems-search-folder-from.html He portado el script de PowerShell a C # como se muestra abajo.

 private static void SearchItems()
{
ExtendedPropertyDefinition allFoldersType = new ExtendedPropertyDefinition(13825, MapiPropertyType.Integer);
FolderId rootFolderId = new FolderId(WellKnownFolderName.Root);
FolderView folderView = new FolderView(1000);
folderView.Traversal = FolderTraversal.Shallow;
SearchFilter searchFilter1 = new SearchFilter.IsEqualTo(allFoldersType, "2");
SearchFilter searchFilter2 = new SearchFilter.IsEqualTo(FolderSchema.DisplayName, "allitems");
SearchFilter.SearchFilterCollection searchFilterCollection = new SearchFilter.SearchFilterCollection(LogicalOperator.And);
searchFilterCollection.Add(searchFilter1);
searchFilterCollection.Add(searchFilter2);
FindFoldersResults findFoldersResults = _service.FindFolders(rootFolderId, searchFilterCollection, folderView);
if (findFoldersResults.Folders.Count > 0)
{
Folder allItemsFolder = findFoldersResults.Folders[0];
Console.WriteLine("Folder:/t" + allItemsFolder.DisplayName);
ItemView iv = new ItemView(1000);
FindItemsResults<Item> findResults = allItemsFolder.FindItems("System.Message.DateReceived:01/01/2011..01/31/2011", iv);
foreach (Item item in findResults)
{
Console.WriteLine("Subject:/t" + item.Subject);
Console.WriteLine("Received At:/t/t" + item.DateTimeReceived.ToString("dd MMMM yyyy"));
Console.WriteLine("Is New:/t/t" + item.IsNew.ToString());
Console.WriteLine("Has Attachments:/t/t" + item.HasAttachments.ToString());
Console.WriteLine();
}
}
Console.WriteLine("Press Enter to continue");
Console.ReadLine();
}

Si todo lo que necesita es una colección de todas las carpetas y subcarpetas en el servidor, puede enviar sus solicitudes y obtener toda la jerarquía de carpetas del servidor en solo unas pocas llamadas. La clave es la propiedad FolderView.Traversal .

Por ejemplo, para un buzón de Exchange con ~ 1,300 carpetas, el código a continuación solo hace 2 solicitudes. Puede configurar el tamaño de su página a lo que quiera, siempre y cuando se mantenga dentro o por debajo del límite del servidor.

Para su información: Exchange Online (Office365) se limita a un máximo de 1,000 artículos en una respuesta. No he probado, por lo que no puedo hablar de límites similares al consultar un servidor de Exchange local.
