With the introduction of Symantec Endpoint Protection (SEP) version 12.1, antivirus definitions will no longer be shareable with other products. SEP will assume full control of its definition sets in order to optimize performance and security.
Providing definitions independently allows Symantec to:
Configure SMSMSE to independently download definitions. See the following article for options: Virus Definition Update Methods Available for Symantec Mail Security for Microsoft Exchange (SMSMSE).
This must be done prior to implementing SEP. Otherwise, SMS will continue to scan emails, but with outdated definitions.
(Page19) of the SEP manual
LiveUpdate no longer shares definitions among products You can use LiveUpdate to update your definitions. However, those definitions will not update your other Symantec products.
To work around this change in LiveUpdate, re-enable the scheduler in your other Symantec products and update them independently of Symantec Endpoint Protection.
