Our SBS 2003 Exchange database got corrupted yesterday morning after a power supply failure. We weren't able to recover any files off our backup tapes (another story) so we didn't have any functional backups of Exchange. Also, we lost all of the logs, so we couldn't do a soft recovery.
I was able to run eseutil /p, eseutil /d, and isinteg (repair the database forcibly, defrag it, and then run integrity checks) to get the database to mount. However, the database shrank from 17GB to 9GB, which means we lost a lot of data. Luckily, everyone runs Outlook in cached mode, so everyone should have an OST file on their local PC.
What should we do from here? Ideally I would love to a) move all of the mailboxes on the old store to a new store and b) force Outlook to resync everyone's OST to the server. Is that possible? Should we do a dial tone recovery? (I'm not sure if this will work for us since it seems to assume you have a good working backup)
