This article is devoted to the common problem all Exchange administrators sooner or later come across – user mailbox damage (logical errors). The logical errors in Exchange mailbox will be represented by such problems as incorrect elements display in folder or their incorrect quantity, search errors, etc. These errors usually appear due to failures on the client’s side, in case when client incorrectly updates MAPI flags during mail folders elements processing, most often this happens with shared mailboxes with which several users work simultaneously. In most cases user can’t suspect errors in his mailbox or folders because formally everything operates correctly. But when some errors happen the user can have mailbox or certain folders access problems, sometimes he can’t view or delete emails or folders which are saved in this mailbox, etc. In case of such user problems Exchange Server administrator previously had to use one of three ways for recovery of damaged mailbox. • Data import from Outlook which is running in cache-able mode to PST file, deletion and creation of new mailbox for “problem” user and lastly data import from PST file to the new mailbox.
This method offers certain quantity of manual manipulations on user’s PC. In some cases you can try to transfer all working user`s mailboxes to the “healthy” mailbox database. In this case you can check store integrity without large quantity of users disabling. However this method is not always acceptable for the different reasons.
• Restore the Exchange database from backup ( ), import data from mailbox to PST file and further data transfer to mailbox. This method has one disadvantage – all emails which got to user`s mailbox after last backup execution time can be lost. Exchange servers administrators had to use all methods described above up to Exchange 2010 SP1 release, when more convenient functional for damaged mailbox logical structure appeared - new Powershell cmdlet New-MailboxRepairRequest. This cmdlet allows to find and to correct all logical errors in Exchange database on application level, moreover the search and errors correction can be performed either for the certain mailbox or for all mailboxes in the database (consistently). There is no need to switch all mail base to off-line mode, and at any particular time only one mailbox will be unavailable, that one for which check and integrity recovery is performed at the moment. Before performing any of described above radical ways to restore of mailbox integrity you should definitely try to use this command. After cmdlet initialization the repair process can be stopped only after mailbox database dismount.
Let`s look at one small case as a practice-oriented example of cmdlet usage. Exchange 2010 user came across emails viewing failure in one of Outlook folders. Appointed folder was recovered from mailbox backup copy. However it appeared impossible to delete the folder itself with a help of MFCMAPI neither from Outlook nor from Outlook Web App nor even from hard or soft. Moreover, Outlook 2010 error gave very little information. Yes Steve, due to some limitations New-MailboxRepairRequest cmdlet does not always work.
In our case, this built-in tool also did not work and then we took help from this third party Exchange server recovery tool: This application successfully repaired, rebuilt, and mounted the databases back to Exchange 2013 server. Hope this will also be help to those who are able to handle severe corruption issues with New-MailboxRepairRequest command line utility. It supports to all versions of MS Exchange server i.e. 2016/2013 / 2010 / 2007 / 2003 / 2000 and MS Outlook. Hi I am completely agreed with Steve Smith and Rachel Bel users.
The PowerShell Scrip New-MailboxRepairRequest doesn’t works on all types of corruption cases in Exchange server and also this feature not available in all Exchange server versions. In case if you are facing any problem which performing this New-mailboxRepairRequest feature then I recommended, try users friendly Exchange Recovery Software which helps to repair corrupted EDB file mailboxes from all version of Exchange server without any trouble.

By default, some tools such as Eseutil and Isinteg are installed to the. Exchsrvr bin directory during Exchange setup. To run these tools globally on your server (from any command prompt), add the full path of. Exchsrvr bin to your Windows Server 2003 system path.
For detailed instructions, see. After adding bin to your system path, you should be able to run Eseutil and Isinteg from any command prompt on your server. You should also be able to run any other tools stored in the. Exchsrvr bin directory. This section contains general information that you should know about if you use Eseutil or Isinteg to repair Exchange databases. For more information about using Eseutil or Isinteg, see Microsoft Knowledge Base articles 812357, ' and 182081, '.' Consider the following information when repairing Exchange databases: • Repairing Exchange databases with Eseutil and Isinteg can cause lost data in the Exchange databases you repair.
For this reason, copy the database files you are repairing before attempting the repair process. (For information about how to copy your database files, see 'Moving or Copying the Existing Versions of the Database Files That You Are Restoring (Optional)' in.) Because you cannot undo changes that were made to a database during the repair process, only use Eseutil and Isinteg as a last resort. As discussed earlier, it is recommended that you recover a damaged database by restoring a backup set instead of repairing a database. • If you use Eseutil to repair an Exchange database, you must have sufficient free disk space for Eseutil to run. If you are running Eseutil /P you must have approximately 20 percent of the size of the database you are repairing on the same drive.
If you do not have that much room, you can use command-line switches to redirect the temp files to a different location. If you are using Eseutil /D, you must have 110 percent of the size of the database. While you can redirect the temp files to another drive as you can with the /P switch, it will dramatically increase the time it takes to repair your database. If it is possible, have ample free space when using the /D switch. • Using the Eseutil and Isinteg utilities to repair a database file takes a substantial amount of time. Typically, it takes much longer to repair a database than it does to restore a database from backup.
• If both utilities run successfully (for example, if there are not any errors at the end of the last Isinteg run), the database is generally considered to be repaired and ready to replace the damaged database. If you plan to put the repaired database back in production you must: • Run Eseutil /P. • After Eseutil /P completes successfully, run Eseutil /D. • After Eseutil /D completes successfully, run Isinteg –fix –test alltests. If you only plan to salvage data from the disk, and do not plan to put it back in production, you can skip step 2 earlier in this section. Skipping step 2 will save time in your recovery process but might cause the database to have indexing and space allocation errors. These errors are not what you want in a production environment, but are unlikely to affect your ability to salvage data from the database.
• If Eseutil and Isinteg cannot fix every error in the database, it is best not to discard a repaired database. After Isinteg is completed, it should report zero errors in the database. If the error count is greater than zero, run Isinteg again until the count becomes zero or the count does not decrement on successive runs. If you cannot get the error count to zero, do not leave the database in production.
Full disabling (unmounting) of mailbox store and check its with Isinteg.exe utility (Information Store Integrity Checker) which allows to correct damages in Exchange. Exchange Server Recovery Software is helpful in various scenarios like hardware or software issue on the server, dirty shutdown, Jet Exchange error and more. As a result, EDB files get corrupt and Exchange Database fails to mount. The inbuilt utilities including Eseutil and PowerShell cannot repair Exchange database,.
Salvage data from it by merging or replicating folders to a new database or by moving mailboxes to a new database. • You can restore data from a damaged database by using another server. For example, you can restore a damaged database to another server, extract data from it using the Exmerge utility, and then insert the data into a new database file. You can also use a recovery storage group on the same server to restore data from a damaged database. For more information about recovery storage groups, see. By default, Eseutil and Isinteg are both installed into the Program Files Exchsrvr bin directory when Exchange is installed.
I am using Backup Exec for exchange backup and it told me I had a corrution in the transaction logs. I'm running Exchange 2010. So I dimounted the db to try to repair the trans logs and db and once I try to mount it I get the error: -------------------------- ---------- ---------- ---------- Microsoft Exchange Error -------------------------- ---------- ---------- ---------- Failed to mount database 'Mailbox Database'. Mailbox Database 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.

(hr=0x80004005, ec=-501). [Server: server.domin.com] MapiExceptionCallFailed: Unable to mount database. (hr=0x80004005, ec=-501) Does anyone know how to correct this?
First use eseutil /mh to confirm that it is in a dirty shutdown state Also check for the 'Log Required' Section And Make sure all the Required Log files indicated by above utility is avilable on the Location. In case if you have the backup of missing Log files then you can copy those log files to the location and try the eseutil /r/i/d again. Then use eseutil /r /l /d to get the database into consistency If the Database is clean shutdown then just mount the store (In case if the Database is clean shutdown but database is still not mounted in this case we need to move the log files ) If you are able to mount the Clean Shutdown database then there is no need to move the log files If you are not able to mount Clean Shutdown database then only move the log files Letus know if you have any further queries Check this out for refrence.
Hi, I have quite a problem on my hands and have been working on it for a few hours with no success. Firstly i dont have a recent enough backup, so i cannot restore. (i know, but there is nothing i can do about it now) The machine went a bit screwy over the weekend and was stuck on a reboot screen when they came in this morning. Everything but exchange came right on a hard reboot. The EMC tells me that 'Mailbox Database' is dismounted. When trying to mount i get gives the error output below. -------------------------- ---------- ---------- ---------- Microsoft Exchange Error -------------------------- ---------- ---------- ---------- Failed to mount database 'Mailbox Database'.
Mailbox Database 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.rapidspillrespo.loc al].

(hr=0x80004005, ec=-515) After a whole lot of ggling i have: Restarted the server again. Restarted all Exchange services quite a few times in between tries. Run an ESEUTIL /r ESEUTIL /p eseutil /ml checked that it is CLEAN Shutdown deleted 216Gb of logs but i still get the same -515 error. No, just the.log files. Exchange 2010 on SBS 2011 I've been looking for something that might make it easy to create a new store and distribute the PSTs or something to each user. Thare arent too many for it to be a big hassle.
Event ID: 454 Description: Information Store (3276) Mailbox Database: Database recovery/restore failed with unexpected error -515. Event ID: 9519 While starting database Mailbox Database, the following error occurred: 0xfffffdfd. Failed to configure MDB. Event ID: 9519 While starting database Mailbox Database, the following error occurred: 0xfffffdfd. Start DB failed. EventID:231 At '2012/08/27 06:32:21 PM', the copy of database 'Mailbox Database' on this server encountered an error during the mount operation. For more information, consult the Event log on the server for 'ExchangeStoreDb' or 'MSExchangeRepl' events.
The mount operation will be tried again automatically. Just sorted it out after a marathon session.
This is what i did: Link-> ran: eseutil /mh 'C: Program Files Microsoft Exchange Server V14 Mailbox Mailbox Database Mailbox Database.edb' found State: Dirty Shutdown ran: eseutil /p 'C: Program Files Microsoft Exchange Server V14 Mailbox Mailbox Database Mailbox Database.edb' and then re-ran eseutil /mh and found Clean Shutdown. As a sidenote, if the database state is Clean Shutdown you can safely remove the logs. Then i cut all log files from C: Program Files Microsoft Exchange Server V14 Mailbox Mailbox Database and pasted them elsewhere (for deletion later if all goes right.) i attempted to re-mount and it still didn't work. I rebooted and found the error had now changed to ec=-528 when attempting to mount.
Link-> I did a bit more digging on the interwebs and found that tmp.edb and e00tmp.log can be moved and recreated. So i cut and moved them, created blank.txt files and renamed them tmp.edb and e00tmp.log Tried to mount one more time and it hopped right on and outlook connected instantly. Check your mailboxes to make sure everything is there, and go ahead and delete the log files if everything is as it should be. There was probably a much more straight forward way, but this fixed it. Hope it helps someone else too.:). Check and Repair the database, Check whether the database state is dirty or clean.
If database state is dirty you have to repair database first and it state is clean then you can go directly for mount the database. May be database state is clean but some of log is creating issue, for that we have to check using chkdsk utility. How to check the database: Run 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 2 Database is not properly shut down so it should be repiared first.
Before attempting any kind of repiar make sure you have backup of database. To repairthe database, run the following command: eseutil /p 'C: Program Files Microsoft Exchange Server V14 Mailbox Mailbox Database Mailbox Database.edb' 3 Re-run the database check from Run eseutil /mh 'C: Program Files Microsoft Exchange Server V14 Mailbox Mailbox Database Mailbox Database.edb' 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 4 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' 5 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.
If the database state is Clean Shutdown you can safely remove the logs.
