hi all, i have Exchange 2010 with only default DB and it's dismounted and when i try to mount it i got and error stated that the E00.log file is missing in the event log there is event ID's : 455 and 9518 and there is no backup how can i fix that and mount the DB. ThanksTarek Khairy

Stop Exchange Services Backup all E*.log files in the log directory Delete all E*.log files from the log directory. Your log folder at this point should only have e00.chk, res1.log, and res2.log. If not , move all other files somewhere else. Restart Exchange Services Mount the database

thanks for the reply but there is no res1.log or res2.log files in the DB folder and there is .JRS files ThanksTarek Khairy

How did the database get into this state, i.e. power outage, system crash, hardware issues?By chance did you have AV on the box configured to scan the .LOG files? If so then you may find the E00.log in quarantine.Have you made a copy of the EDB to an alternate location?Have you reviewed the System & Application event logs to find, review and correct critical issues Need to know the answers to above to give you more feedback since it very well could be you have an issue with the Disk subsystem, AV configuration quarantined or deleted E00.log, etc. Could be as easy as finding out what happened to the log, or you may need to repair the database, or use a 3rd party utility like Lucid8's DigiScope 4.0 http://www.lucid8.com/product/digiscope.asp that can do a Forensic Mount of a DB to allow access to all mailboxes, folders and messaging items so that you can either export to PST & MSG or Import/Migrate all data from an Offline database to a Production\Live server (even cross version i.e. 2003 --> 2007 --> 2010 Troy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers with Lucid8's DigiScope

thanks for the reply but there is no res1.log or res2.log files in the DB folder Hi Tarek, If the database is in clean shutdown state(ESEUTIL /mh), you can move all files except the .edb file to another folder for backup , then try to mount the database again. But you may also need to check why the E00.log was lost. Frank Wang TechNet Community Support

hi thanks for the reply i followed the solution to move the logs and start the services again and the logs created but when i try to mount the DB or run esutil /mh i got the following error : Error -1032= ' JET_errFileAccessDenied'= File cannot be accessed any help Tarek Khairy

That error designates that the file is currently locked by another process so this database is OFFLINE, correct? if so then check to ensure that your antivirus, backup application or some other product is not trying to access and therefore has a lock on this file. If you cannot figure it out you may need to reboot the server.Does the disk its located on have free spaceHave the rights changed for the folder that db is located Check your System and Application event logs for errors and correct any problems found Troy Werelius www.Lucid8.com Search, Recover, & Extract Mailboxes, Folders, & Email Items from Offline EDB's and Live Exchange Servers with Lucid8's DigiScope
