Make sure that a file system-based antivirus program running on the Exchange Server is not scanning the Exchange IFS drive (M drive). Additionally, make sure that any backup software used is not backing up the Exchange IFS drive. If the corruption cannot be isolated or corrected, restore the data from a backup.
