Depends on what you changed. :-) You might have just wiped out some mailboxes, the attachment table, or something else that wouldn't make the database unmountable (just unusable). If you're goig to do this, make sure you /kill/ the IS process and /then/ stuff something into the databae. That'll ensure that the database is in an inconsistent state when you mount (or try to mount) it. >will >isinteg and eseutil fix the database? No. A restore will, followed by a replay of the log files. -- Rich Matheisen MCSE+I, Exchange MVP MS Exchange FAQ at http://www.swinc.com/resource/exch_faq.htm Don't send mail to this address mailto:h.pott(a)getronics.com Or to these, either: mailto:h.pott(a)pinkroccade.com mailto:melvin.mcphucknuckle(a)getronics.com mailto:melvin.mcphucknuckle(a)pinkroccade.com

From: Oliver Moazzezi [MVP] on 4 Nov 2007 18:35 Do this if this is just a test scenario. Dismount the database, then rename the files, say priv_old.edb and stm. Mount database. You will find it will still mount, but create an empty database, you can, use any backups you have to perform your DR. If you are just wanting to play around with eseutil though however, you will have to come up with a really good way of corrupting the database. Oliver

First try to determine why. If its unmountable after troubleshooting, restore from backup. But, that doesnt mean understandin how eseutil and isinteg work and how they differ isnt woth knowing. So, mess around with those utils on a test store if you want. >"Oliver Moazzezi [MVP]" <o.moazzezino(a)spamfreenet.co.uk> wrote in message >news:OBhZ2VzHIHA.1316(a)TK2MSFTNGP02.phx.gbl... >> < will isinteg and eseutil fix the database? >> >> That isn't a good DR plan, restoring from your backup is. a hard repair >> (eseutil /p) is always considered the last resort if no good backups are >> available. >> >> Oliver >> >> >
