Exchange 2003 Recovery – No back up.

pts.
Tags:
Microsoft Exchange
I have pub1.edb, priv1.edb, pub1.stm and priv1.stm. I also have some log files. The exchange server has completely failed, and the back ups don't work. The company has since installed a new server, and a new AD. Can I recover the mailboxes from the files I have and restore them to new mailboxes? Many thanks for your time. Bruce Clark

Thanks. We'll let you know when a new response is added.

Do you have a backup of your old Active Directory? All exchange configuration data is saved in the AD. You can try to make a recovery installation of the exchange server. This is a supported task to move or recover an exchange server:

I think there is no way to restore an exchange server with standard tools without having the AD containing the exchange org.

It may be possible to access the IS, even a corrupted one, with “power controls” from “Ontrack” to copy the data to an PST file. But this is a very expansive way. You can get an free eval copy to test the access on the Ontrack home page:

Good luck!

    Hi, I had the exactly same problem some months ago and all I did was to use Ontrack Power Controls, it's a very very good tool. After I had my new Excjange server, I used Ontrack ..... and I copied the old Exchange data to the new server, of course it's not so easy to do that, you have to go user by user but what I cared was to recover the information. Good luck Calixto

    Quest's recovery manager for exchange does a great job of this. It can literally mount your EDBs and STMs right from the tape (or other) backup. Then you can do all sorts of stuff with the data to include exporting to pst files like exmerge. It may work with your EDB and STM and logs but you'd have to roll the dice and try it. You can get a trial copy. http://www.quest.com/recovery_manager_for_exchange/

    In the future you might want to backup by individual mailbox as well as by stores. If you had backed up by mailbox in the first place.... To do any recovery you should probably do this "offline" -- especially since, from what little you said, your original failure might have been malware related. Plus I would not play with restores the first time agaisnt your live Exchange server. So for safety build a temporary DC to capture AD information from your live network. Well there are ways around live AD but this should make things go faster. Take it off your production network to play with. Add Exchange. Use your exact Exchange site, server name etc if you have the old documentation to make things easier yet. Back on Exchange 2000 I have just dropped those files into a virgin install of Exchange instead of the empty files then used Eseutil and similar tools to rebuild indexes etc as if the indexes etc were corrupt to make things live. I am familarly sure you still can on 2003. If you can pry open the stores then you can look up the procedures for renaming this experimental Exchange server so you can join it to your live Exchange structure and move mailboxes. Or backup Exchange by individual mailbox or to .pst's. Actually these attempts to recover old email go a lot better if completed before the new server is populated with mailboxes -- or if the new mailboxes have a different naming convention. I always tried to work the two projects in parallel jumping back and forth as I waited for some install aspect to complete. As is be careful you don't get over enthuasiastic with successful recovery of old email and wipe out the new mailbox of the same name!

    A previous comment had a malformed link. Correct link is:   http://www.msexchange.org/tutorials/Recovering-Failed-Exchange-2003-Member-Server-Using-Disaster-Recovery-Switch.html   If it can be done at all, those are the steps that should be followed.   Tom

    If backup is not available, it may create severe problems and you may face critical data loss situations. You may Execute ‘Eseutil’ with ‘/p’ switch to repair the damaged database. But make sure to backup the database before running this command line tool as you may face some data loss issues after running this inbuilt tool due to its destructive nature.

    If eseutil /p repair tool also does not work, you may take help from a third party program. There are many third party tools available online and most of them come with free trial version. I would suggest to run and check their free demo version. It will help to choose the best one. Here is one such globally used and one of most recommended tool by MVPs and Server admins: http://www.recover-computerdata.com/exchange-server-recovery.html
