Exchange Logs

Here's an interesting thing I learned about exchange logs. You know that you shouldn't be deleting them because Exchange should be taking care of that for you. But what if Exchange isn't clearing the logs for you? I have one customer that hasn't done a backup in over a year. We're going to install a new server on his site because a)the email server is at it's storage capacity, and b)he's still on Windows 2000 Server. In preparation for the new server I need to back up his current server. I bring the tape drive from my office and install it on his server and perform a full backup using ntbackup. Today he has over 40GB of storage space available on his harddrive. What happened? Did simply clearing the archive bit on all those log files give Exchange the okay to delete them? All my other customers do a daily backup so I've never seen this behavior before. I'll definitely have to keep this in mind for the future.
