I have been trying to find out what exactly the priv1.html file is on Exchange 2000, but cannot locate much information. I know that priv1.edb is the main databse for Exchange. I am assuming that since this file changes in size almost every second that inbound and outbound mail transactions are written to this file before the database, but would like some confirmation or correction on this thought. I am currently seeing this HTML file grow to 82GB in size, just three days ago it was 60GB. Any thoughts?
