I have a sbs 2011 setup, 2 of my raid 5 disks failed which costed me loosing most of my data and because i didnt have any backups I hardly managed to recover the EDB file for the  mailboxstore database. if I have the EDB file only is it possible to revover the mailboxes from it? are there any ways I can export PSTS straight from the EDB file?

yes there are some tools out there - i haven't had to do this myself

but if you have a safe copy of the EDB's you should be able to recover something from them with exchange recover

http://blog.chrislehr.com/2009/10/exchange-2010-recovery-scenario-1.htm - its a bit specific but the steps to mount the EDB file should hold for your scenario

Have not tried this in a 2010 disaster scenario but worked fine in 2007.

You can extract all your AD Accounts from the exchange database and recreate them to same time.

instead of trying software to extract it why not try the steps that would enable you to mount the database that is in the link i posted and the first steps of the link Neilsr posted?

because that's for exchange 2007 and when it says:

Now, let’s go to the path where the current database is located and we will remove the current database file (mailbox database.edb). Then, we will copy our old database on to the same path and we will rename it “Mailbox database.edb”. After that we can go back to the Exchange Management Console, click on the dismounted database and click on Mount Database in Toolbox Actions.
how would you do that while the DB is mounted which I tried to dismount and replaced the current EDB and couldnt moutn the DB still!

the same applies to 2010 as the base functionality is the same.

are you saying that you have the mailboxes back but just with missing data?

here are specific 2010 steps using the recovery database functionality

you shouldn't need the log files if you have the edb file in a clean shutdown

you should try and clean it up with ESEUTIL to repair it - you may lose data out of it as you don't have the logs but at least then you will be able to start recovering something.

If you are unable to do it with exchange recovery then you will probably have to buy a tool
