Exchange 2010 Error: Unable to mount database

Q. My Exchange server crashed and I'm trying to mount the database, with no luck.

This is the error that I get:

--------------------------------------------------------
Microsoft Exchange Error
--------------------------------------------------------
Failed to mount database 'Mailbox Database'.
Mailbox Database 0610509261
Failed
Error:
Couldn't mount the database that you specified. Specified database: Mailbox Database; Error code: An Active Manager operation failed. Error: The database action failed. Error: Operation failed with message: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-515)
. [Database: Mailbox Database, Server: server.domain.local].

An Active Manager operation failed. Error: The database action failed. Error: Operation failed with message: MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-515)

MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-515)

A. You have a corrupted database or corrupted logs. Several tests need to be performed, to see what the issue is (this is an example for Exchange 2010, but it works for previous versions as well):

Check and Repair the database

1. Check the database:

eseutil /mh "C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\Mailbox Database.edb"

Look for the following in the output: State: Dirty Shutdown

1.a Since the database has not been properly shut down, it needs to be repaired.

Make sure you make a backup of the database before attemting any kind of repairs

To repair, run the following:

eseutil /p "C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\Mailbox Database.edb"

1.b Re-run the database check from 1.a and if all goes well, you should see this somewhere in the output: State: Clean Shutdown

You can try mounting the database. If it mounts, you are good to go, if it doesn't you have to check the logs:

Check and Repair the database logs

2. Check the exchange logs (don't forget to specify E00 - the starting sequence for the logs)

eseutil /ml "C:\Program Files\Microsoft\Exchange Server\V14\Mailbox\Mailbox Database\E00"

2.a There will be a list of logs and depending on their state, you may get an error. (They should all say OK, if the logs are clean) Errors vary, but most likely it is a file corruption and needs a chkdsk to run.

As a sidenote, if the database state is Clean Shutdown you can safely remove the logs.

We had also encountered similar problem in our Exchange 2010 mailbox store and the reason was corruption. We ran ESEUTIL /p tool to fix it but no luck. Then, one of MVPs suggested to go with a third party tool as the database was severely damaged. He shared a link with us to download and try it from the web: https://www.serversdatarecovery.com/exchange.html

I was surprised to see the output of this third party application as after few minutes, it displayed all data in their original format. And we successfully repaired and mounted all data with the help of this tool without any data loss.

hello first of all thank you for this,

I was doing a vmdk shrinking in vmware datastore as my previouse colleagues used C: drive as a thick provisioned.

I moved mailboxes DB,PF DB to another drive and and separated transaction logs too . taken a full backup but I forgot to add the newely created PF_DB drive to it.

after full backup I shrinked the vmdk file and it worked fine when i used the third party tool to shrink the C: drive it screwed the OS :P hahahaha.

so restored bakup within night it came back online mailboxes didnt had issue. PF was down

I restored the PF database from day before backup and ran this glorious command it fixed :) :)

but after I received a clean shutdown also it was saying =-1209 error which means traansactions logs was not found. but waited 15 minuets. test again mounting it worked :)

thank you so much , I know this pain working as a senior network engineer for consultancy and my client was financial MGMT company.

thank you again have a nice day

it fixed up the problem!

Thanks for this post, it works like a charm. I've checked the database and it was "ok", than I stopped the services and deleted the logfiles. Than I started the services again and mounted the database. :)

Unable to mount database

2 Wednesday, 29 August 2012 03:37

Brian Lenin

Running eseutil /p (hard repair) method may sometimes leads to serious data loss issues in the database. So, it is highly advised to keep a copy of databases before running these command line tools. If log files are missing and database files are severely damaged, it is good to use most recent backup file or a third party tool like Stellar Phoenix Exchange Server Recovery: https://exchange.stellarservertools.com/

thanks
Lenin

Thanks.
