Exchange 2019 CU14 New Setup Options

Exchange 2019 CU14 will enforce the use of Extended Protection (EP) by default.  This is the desired security configuration as we need to harden the traffic to help prevent Attacker In the Middle (AiTM) style attacks.  This is not a new thing, and the Exchange team added support for EP in the previous releases as an optional (but strongly recommended) feature.  The intent was that customers would … Read the rest “Exchange 2019 CU14 – Extended Protection New Setup Command Line Options”
