// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();

// Use your previously obtained access token here:
http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN";

// This example will search /Inbox for a message we want to delete.
// First we need to get the folder ID for /Inbox.
// Then we'll search for messages based on some criteria, and delete the matching messages.

// Get the folder ID for /Inbox from the folder map created by this example

Chilkat.StringBuilder sbMap = new Chilkat.StringBuilder();
sbMap.LoadFile("qa_data/outlook/folderMap.xml","utf-8");
htFolderMap.AddFromXmlSb(sbMap);

// Get the ID for the "/Inbox" folder:
string folderId = htFolderMap.LookupStr("/Inbox");
if (htFolderMap.LastMethodSuccess != true) {
    Debug.WriteLine("Folder ID not found");
    return;
}

bool success = true;
Chilkat.JsonObject json = new Chilkat.JsonObject();
json.EmitCompact = false;

// Search for emails in this folder with the phrase "Amazon SES" in the subject, and return only the id and subject.
http.SetUrlVar("folder_id",folderId);
http.SetUrlVar("select","id,subject");
http.SetUrlVar("filter","contains(subject,'Amazon SES')");

Chilkat.StringBuilder sbResponse = new Chilkat.StringBuilder();
