We have just brought up a client in a new server environment. We are running the same configuration as we have used for multiple other clients, but we are getting a very weired and problematic issue on this server.
The Exchange Server 2010 runs inside of a Hyper-V session. 6GB ram assigned to it and about 35 or so active email account. They receive about 1000 emails per day. We imported all of the PST files over the weekend (they were on on a domain prior to this).
We have an issue where the system is generating about 2GB of transaction logs every 1/2 hour. We have verified that there is no open relay and no abnormal amount of email messages being processed.
Per other online help documents, we disabled SMTP for a period of time and the transaction files continue to accumulate at the same accelerated pace.
We can run a backup and truncate the logs, but they keep continuing to build.
The problem appears to be something in the store that is running and creating the transactions. But we cannot fully determine what is causing the issue.
