Exchange Server 5.5 Service Pack 4 Overview

Published: May 21, 2001

This service pack addresses server issues that were previously available as Microsoft Quick Fix Engineering (QFE) updates. Service Pack 4 (SP4) is a cumulative release that contains all of the updates for Exchange Server 5.5 to date, including the feature enhancements and utilities from Service Pack 3 (SP3). We recommend installing the service pack on all servers running Exchange Server 5.5.
