AlwaysOn High Availability doesn't work , can't activate it I am trying to activate the high availability
on my SQL server and getting below message:


SQL server version: Microsoft SQL Server 2017 (RTM) - 14.0.1000.169
(X64) Aug 22 2017 17:04:49 Copyright (C) 2017 Microsoft Corporation
Express Edition (64-bit) on Windows Server 2012 R2 Datacenter 6.3
 (Build 9600: ) (Hypervisor)
Operating System: windows server 2012.

Appreciate any help.
You need Enterprise edition for fully functional Always ON AG and a minimum Standard edition to use the basic Always On AG. Express edition of SQL Server does not supports Availability Groups
