If you uninstall this cumulative update package, Exchange Server 2013 is removed from the server. Also, there are no way to uninstall CU10 from the Exchange 2013.


From what I can see, we don’t need to install CU1 or a later cumulative update for Exchange Server 2013 when you install Cumulative Update 10. We need to upgrade our Exchange 2013 SP1 server with the Cumulative Update 10 (CU10). CUs are a complete installation of Exchange 2013 and can be used to install a fresh server or to. Exchange 2013 CU19 has been released to the Microsoft download centre! Exchange 2013 has a different servicing strategy than Exchange 2007/2010 and utilises Cumulative Updates (CUs) rather than the Rollup Updates (RU/UR) which were used previously.
