I'm trying to recover a database from a storage group (SG) that contains three databases. I care about only one of the databases, but when I try to use Eseutil, it complains about the missing databases. How can I recover just the one database?

When you use the /r switch to perform a soft recovery, Eseutil will always try to play back the log files for all databases in the SG. Because the logs can contain transactions for all databases in the SG, this behavior is to be expected. To force Eseutil to ignore the missing databases, add the /i switch to your command line.
