Code example for fetching folders and their counts. In this example, we are listing all first-level folders, and adding them to a common class list of folders, with a NewMessageCount object in there. Key is the Folder.Bind(myService, folder.Id).UnreadCount section.

public List ListFolders()
    {
        try
        {
            List myFolders = new List();
            Common.MailFolder myFolder;

            List myExchangeFolders = new List();

            FolderView myView = new FolderView(10);
            myView.PropertySet = new PropertySet(BasePropertySet.FirstClassProperties, FolderSchema.DisplayName, FolderSchema.Id);
            myView.Traversal = FolderTraversal.Shallow;

            FindFoldersResults myResults = myService.FindFolders(WellKnownFolderName.MsgFolderRoot, myView);

            foreach (Folder folder in myResults)
            {
                myFolder = new Common.ICE.MailFolder();
                myFolder.NewMessageCount = Folder.Bind(myService, folder.Id).UnreadCount;
                myFolder.FolderId = folder.Id.ToString();
                myFolder.FolderName = folder.DisplayName;
                myFolders.Add(myFolder);
            }

            return myFolders;
        }
        catch (Exception ex)
        {
            Logger.Log.Error("Exchange Helper - List Folders", ex, Utility.GetUserId());
            return null;
        }
    }
