Using FindItems with EWSMA to display All Mail Items from an email

Question

I would like to use the EWSMA to show all emails from a given user.  Currently my sample code just shows the emails from the given user in the Inbox and not the sub-folders.  How can I ensure that FindItems will search the subfolders as well?
Also, what is the property to check if the email is flagged in Outlook and on the Exchange Web App?  I am testing against an Office365 Exchange account.
private static void SearchItems()
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();

Hi Luke,
while the EWS managed API indeed has a FindItems method which can search multiple folders at once, that method is marked internal. So, without some serious Reflection you won't be able to call it.
What you can do is call EWS directly. And you can combine it with the EWS managed API, to leverage AutoDiscover.
var service = new ExchangeService(ExchangeVersion.Exchange2007_SP1)
{Credentials = new NetworkCredential("username", "password")};
service.AutodiscoverUrl("mailaddress", url => true);
var binding = new ExchangeServiceBinding
Url = service.Url.ToString(),
Credentials = new NetworkCredential("user", "password")
var findItems = binding.FindItem(new FindItemType
ParentFolderIds = new[]
new
DistinguishedFolderIdType {Id = DistinguishedFolderIdNameType.inbox},
new
DistinguishedFolderIdType {Id = DistinguishedFolderIdNameType.sentitems},
Item =new
IndexedPageViewType { MaxEntriesReturned = 512, MaxEntriesReturnedSpecified
= true},
ItemShape = new
ItemResponseShapeType { BaseShape = DefaultShapeNamesType.AllProperties},
The code above will search both, the Inbox and the SentItems folder.
As for the Flag: You'll have to access some extended properties here. See
