Please excuse my lack of experience. We just put up our first Exchange 2003 server this month and began migrating mailboxes from our 5.5 server. I noticed a very large amount of files in the MDBDATA folder where the priv1.edb file is. They have names like 30000A1d.log and are all 512o kb in size. There are hundreds of these. Can I get rid of these and how should I do it. I hate to delete something that I need. Thanks Byron
