Exchange Transaction logs not flushing after a backup

We have 2 exchange 2003 servers with multiple database stores on each. Each server has it's own incremental backup job. Each job seems to be identical. EXC03 server's logs are being flushed nicely after a backup.

EXC04 server's logs remain after a backup....creating a concern of disk space issues. I did migrate mailboxes off of exc04 a week ago......also, I dismounted and moved an empty data store onto a SAN. The store is dormant and is still dismounted. The other stores on EXC04 are still as is.....and are being backed up. However, the logs are not flushing. Any ideas?

The logs are only flushed after a full backup of the information store (no brick level backups). Also, this is only done if the backup was OK. Did you check the BE Logs?

If the date on the logs is a couple of weeks old......would it hurt to delete these out?

I would suggest checking that at least /some/ of your logs get deleted when you do a backup. That would indicate that the remaining ones are indeed orphaned, and therefore unlikely to be deleted automatically. There's some more guidance here:
