How to fix Exchange database Dirty Shutdown error?
Updated On - April 18, 2025
While trying to mount a database, Exchange administrators may sometimes face a dirty shutdown error. This dirty shutdown error will not let them mount the database as it is in an inconsistent state. It is the sudden termination of the Exchange Server (due to reasons like power loss) that causes a dirty shutdown error.
When you make changes in an Exchange database, Exchange records updates information in transaction log files before committing to the database. But when the log files are not replayed into the database and the modifications you have done are not reflected in the Exchange Database. In such case, your database is in an inconsistent state. This results that the log files are corrupt, missing, or damaged. So, when your database is inconsistent and you are trying to mount this, you will face a dirty shutdown error.
Reasons of Dirty Shutdown error
There are many reasons of dirty shutdown error:
- Faulty Exchange server updates or relying on outdated versions.
- EDB files are not detached from log files properly.
- Log files are missing from the server.
- Log files are damaged.
- The server is unable to read the log files.
