Hi,
Today you release this Security Update for Exchange:
https://support.microsoft.com/en-us/help/4018588/description-of-the-security-update-for-microsoft-exchange-july-11-2017
Our servers are Exchange 2013 CU15.
We downloaded:
Security Update For Exchange Server 2013 SP1
and Security Update For Exchange Server 2013 CU16
But it doesn't work. It show this error:
The upgrade patch cannot be installed by the Windows Installer service because the program to be upgraded may be missing, or the upgrade patch may update a different version of the program. Verify that the program to be upgraded exists on your computer and that you have the correct upgrade patch.
Exchange 2013 CU15 doesn't need the patch?
Regards
