We want to do defrags (eseutil) of our Exchange 2003 Information stores. We would like to do them one information store at a time to limit downtime (we have 12 Information stores across 2 virtual exchange servers on a 3 node cluster). Can we pause the email queues so that no email can go to/from only one information store at a time? The reason is that after the defrag is complete and we re-mount it, we want to do testing on it before allowing mail to resume to/from it.
The only thing I can see is to stop all the mail queues and SMTP service per Virtual Exchange Server. We want to do this on a per information store level, or even per storage group if possible.
