Hallo. I have a issue with my exchange2007.
First we were uanble to send to a specific user all others users seems to work fine - when we send to the user it gives us the follwing error:

There's a problem with the recipient's mailbox. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.

#550 5.2.0 STOREDRV.Deliver: The Microsoft Exchange Information Store service reported an error.

after further investigations i found out that the ntbackup failed last nigth with the following error:
The 'Microsoft Information Store' returned 'Error returned from an ESE function call (d).

' from a call to 'HrESEBackupRead()' additional data '-'The 'Microsoft Information Store' returned 'Error returned from an ESE function call (d).

' from a call to 'HrESEBackupRead()' additional data '-'
The operation was ended.

For me it seems like a corrupt database.

I have run a eseutil /mh against the database and it says that it is in a "clean shutdown" state.

I have run a eseutil /ml against the log files and there is 5 corrupted files

I am able to restore the backup from monday night, but will miss about 3 hundred log files from the first corrupted log files to the newest log files.

I checked the .chk file and all log files is comitted to the database - so i have started a repair process on the database. Is this the right way or what do you guys think.

Or is it not a coruuptes database?

Best regards michael

Can you move the mailbox to a different store?

Which switch did you use to repair the database? /r, /p, /c?

I only have one exchange server so i could not try to move mailbox to another server.

I ran the folloing utilities:
1) Eseutil /p
2) Offline defragmentation
3) 2 times ISINTEG �fix -test alltests until all fixes and error were 0.

The 3 steps solved my problem but i do not know what i have lost during the repair.

You will never know what is lost. Yeah, you will know "how much" by having a look at database size "before-after" the defragmentation.

Try understanding how complex can database look like from this article.

There are many causes responsible for corruption of Exchange server. The first solution is to use the in-built utility, such as ESEUTIL or ISINTEG tools. However, at times of severe database corruption, these tools fail to repair the damaged .edb file. Actually, these tools repair database by removing the corrupt pages with the database file. In such cases, using an third party Exchange server recovery software is best option to repair and recover data from damaged server database.

One of the best and globally used third party tools, can be downloaded from here: http://tinyurl.com/ne4q6lb

This software is designed with powerful scanning method to scan the damaged database data completely. After scanning the corrupt or damaged database file, it gives the option to save the data either into .edb file or .pst file. Versions supported by the software are MS Exchange Server 2016, 2013, 2010, 2007, 2003, 2000, 5.5, and 5.0. Free demo version of the product can also be evaluated before going to get full version.

Whenever Exchange Server Database corrupt, t is really very bad situation faced by the Exchange server administrators. It is true that eseutil /p repair method remove the corrupt or unrecognized items from database (.edb) file to bring the database into consistent state. However, there are some third party tools which rebuild the corrupt items and make the database consistent. Thus, users should take backup on regular basis to prevent data loss situations and also to handle the disaster situations efficiently. In the absence of valid database backup, it is good to use a third party tool like this: http://bit.ly/1QvJlkZ
This tool has been designed with strong scanning modes to handle the corruption and to prevent data loss issues. This software rebuilds the damaged items and enables the users to directly mount the database to MS Exchange Server.
