You may occasionally run across a crisis while using Microsoft Exchange Server, wherein the Exchange mailbox stores belonging to a particular Storage Group fail to mount. Generally, this behavior is seen after an abnormal termination of the Information Store service, putting your database into a 'Dirty Shutdown' state.
An Exchange database in 'Dirty Shutdown' state may indicate damages in your Exchange database files, i.e. '.EDB' and '.STM'. In an event of Exchange dirty shutdown, you may get the below error after running 'Eseutil /k' command against your database:
ERROR: database was not shutdown cleanly (dirty shutdown)
Operation terminated with error -550 (JET_errDatabaseDirtyShutdown, Database was not shutdown cleanly. Recovery must first be run to properly complete database'
In order to work around this problem, you need to stop your Information Store service and back up everything (edb, stm, and log files) to a different disk. You must ensure that you have sufficient amount of free disk space. Now, follow the steps given below to get your database back to the clean shutdown state:
This command replays the transaction log files to make sure that all the database operations are successfully completed.
