Let me begin by saying that I recently (within the past week) took over Exchange admininstration when our admin left. Of course, something had to go wrong. One of our log drives is filling up and is almost out of drive space. We have an Exchange 2003 Server with 3 storage groups. The information store gets backed up every night. The logs for 2 of the storage groups are being automatically removed after each backup, however, there are log files for the third storage group that are over a month old. I read several articles that said you have to be careful about deleting the log files because they may not have been commited to the database yet but wouldn't it be safe to delete the log files that are at least a week old?
