What Is Dirty Shutdown of Exchange Server

The term Dirty Shutdown implies that the database is down and is not in a healthy state. The main reason for the dirty shutdown is the inconsistency in transactions of the transactional log files. If the EDB file is not properly detached from the transaction log files, the database goes in the dirty shutdown state. Then, the Exchange server is unable to access and read the transaction logs and lead to a transactional discrepancy.

When you encounter Exchange Dirty Shutdown, you can manually fix it by using Eseutil utility. If you fail after this method, you can still use EaseUS Exchange Recovery tool to help you automatically recover and repair mailboxes (EDB) files and contents in Exchange 2019, 2016, 2013, and 2010.

Manually Fix Exchange 2016/2013/2010 Dirty Shutdown Error Using Eseutil Utility

Follow the steps shown below to fix the issue and recover Exchange Server database after the Dirty Shutdown. If you are new to Exchange and know little about the Eseutil commands, you'd better use the automated way to resolve Exchange Dirty Shutdown error without more data loss.

1. Back up all the database files (.edb and .stm) and logs files to somewhere else.

2. Free up the disk space: To recover Exchange database from a Dirty Shutdown state, you need to ensure that there is 110% of empty disk space.

3. Check the database consistency. Run the following command to check the consistency of the database.

eseutil /mh "path of the priv.edb" (eg: eseutil /mh "c:\db\mailbox database.edb")

4. Check Exchange database status. The status of the database should be "Dirty Shutdown".

If the Exchange shows Dirty Shutdown, you can first try the "Soft Repair" to fix the issue. And if that does not work, then try using "Hard Repair". Let's look into each method:

Run Soft Repair

eseutil /r – run it from database log folder and specify log chk file (c:\dblog>eseutil /r E00).

or specify the following commands:

eseutil /r "prefix"/l > /d
Eseutil /r E00 /l c:\dblog /d c:\db

Check The DB Consistency: Check the database consistency again and if it shows a clear shutdown, directly go to Step 6. But, if the soft repair didn't work, then run the hard repair.

Hard Repair

If Soft repair doesn't work, try a hard repair.

Eseutil /p ,  eg: Eseutil /p "c:\program files\exchangesrvr\maildbdata\priv1.edb"

5. Defragment the database. Now defragment the DB using the eseutil /d command applied to the mailbox database file.

Eseutil /p , eg: Eseutil /p "c:\program files\exchangesrvr\maildbdata\priv1.edb"

After running this command, remove the log files in the MDBDATA folder before commencing with the database mounting.

6. Check database integrity. This command takes up to 10 minutes per Gig of Data. If you don't have time (runs at about 2 to 10 minutes per Gig of data) you can skip it after soft recovery. But, if you have attempted hard recovery, then you must run it.

isinteg -s "name of the server" -test alltests

If this integer check fails, then run the following command.

isinteg -s "servername" –fix –test - alltests

Run this command repeatedly till all the errors reach the level 0, or the status starts showing no changes.

7. Check the database consistency again. Now check the database consistency with eseutil /mh command, and it must show "clear shutdown" as the status.
