The organization's Exchange servers are isolated from the internet and cannot successfully retrieve new AntiVirus definitions via LiveUpdate. How to ensure definitions will be updated without internet access?
Configure an internal LiveUpdate Administrator 2.x (LUA 2.x) server to retrieve definitions for SMSMSE and distribute them to SMSMSE servers.
NOTE: This document is intended as a walkthrough to download virus definitions for SMSMSE 7.9 or later on a 64-bit computer by using LUA 2.x. For more general LUA 2.x information, see here. LUA 2.x must be version 2.2.2 or greater. Download the latest version of the LUA here.
The LiveUpdate Administration Utility lets you set up an intranet HTTP server. This mechanism lets you handle LiveUpdate operations for your network.
The LiveUpdate Administration Utility is available at the following location:

If you set up your own LiveUpdate server, you must edit the LiveUpdate configuration for Mail Security to point to the local LiveUpdate server.
