@elrebib, Exchange 2010 SP2 is supported until April 8th 2014 (See: http://support.microsoft.com/lifecycle/search/default.aspx?sort=PN&alpha=Exchange+Server+2010
support.microsoft.com/.../default.aspx) and customers will continue to receive normal support efforts from Microsoft as defined by the support lifecycle policy (Here:
http://support.microsoft.com/gp/lifepolicy
support.microsoft.com/.../lifepolicy) until that date. We continue to release security updates as necessary for SP2 as is seen here with SP2 RU7.
@chris, if you utilize the WebReady Document viewing feature in OWA we would recommend you apply SP3 RU11 to get the latest fixes to the Oracle Outside In library files which WebReady Document Viewing utilizes. This is what MS13-061 (Here:
http://technet.microsoft.com/en-us/security/bulletin/ms13-061
technet.microsoft.com/.../ms13-061) is for.
