have @ deleteitems method on exchangeservice class https://msdn.microsoft.com/en-us/library/microsoft.exchange.webservices.data.exchangeservice.deleteitems(v=exchg.80).aspx allows send batch deleteitem request. suggest page deletes though @ no more 1000 items @ time else may have issue throttling and/or requests timing out.
