Exchange Server 2013 CU10 is now available for download.
Just as previous CU versions, this version can be used to perform a new installation of Exchange Server and you don’t have to install CU1, CU2… before you install this one.
CU10 doesn’t include any new Schema updates but depending on your current Exchange version you may need to do a Schema update anyway.
The Build of this version is: 15.00.1130.007
Besides all issues this CU update resolves, it is particular interesting.
This version will be the minimum version of Exchange Server 2013 you need to co-exist with Exchange Server 2016.
So, in order to be ready for Exchange Server 2016, this CU update need to be installed.
