Symantec Endpoint Protection running on Exchange Servers: Fool me twice....shame on me

Note to self:  Disable all instances of Symantec Endpoint Protection (SEP) on ALL Exchange servers before and during a calendar migration.

Why?

* Insertion throughput dropped 99%: from 750 transactions/minute to four (4) transactions/minute.
* SEP stripped all of the Sumatra strings we associate with calendar items to process messages.

This product bit us two years ago.  It just bit us again.

It's your choice to deploy SEP in your Exchange environment (or not.)   But do not deploy SEP during a Sumatra calendar migration.
