Yesterday we had a power failure and the UPS did not work (it has worked perfect before). Everything seem to be ok when I started all the servers again except of the mail, when I try to mount the store I get the following message: “The database files in this store are corrupted”
Server: Exchange 2003 running on a Small Business Server
Latest full backup: one week old
Backup program: Backup Exec 9.0
This is what I have done:
1. Copy every file in the MDBDATA folder (edb, stm, log)
2. Run Eseutil /d for priv1.edb
3. Run Eseutil /p for priv1.edb (took seven hours)
4. Run Isintig –fix –test alltests, now it breaks down. Isintig fails with the following error: Isinteg cannot initiate verification process. Please review the log file for more information. The problem is that there is no log file created.
5. Giving up on this route I decide to do a restore from the backup, it fails with the following error: Unable to read the header of logfile E00.log. Error -501, and the error: Information Store (5976) Callback function call ErrESECBRestoreComplete ended with error 0xC80001F5 The log file is damaged.
My conclusion is that E00.log is damage, so how can I repair it so that I can restore the database? Or should I give up and try some other route?

Are your users connecting to Exchange via Outlook in cached mode? If so, you could restore the IS from your last full backup and let the Outlook clients resync with the mailboxes. This will take anything in the OST file that doesn't exist in the restored mailbox and put a copy in the mailbox.
If that's not an option, then my suggestion is to read this:
