Restore a public folder database by overwritting with a restored .edb? *Urgent :(

Hi Guys,

I'm currently running Exchange 2010 SP3 running on Server 2012.

My problem is this. I'm almost done migrating my exchange from 2007 to 2010, when I come to stage of deleting the replicas of the 2007 exchange server (so that I can uninstall the exchange 2007), I ran this command instead " remove-publicfolder" and it deleted my public folders from BOTH my 2007 and 2010 servers!

In essence, what I did was this:

I have managed to recover a .edb file from the last good backup (2 days before this dumb move). My question is, how should I approach this restore?

I'm currently using a 3rd party tool to extract .PSTs from the edb but it's slow and I dont know if it would be 100%....

Assuming its ok to overwrite whatever is left for the pubfolder in the exchange 2010 since last backup, what should i do?

Thanks in advance!

Was the backup an Exchange aware backup?

As you wiped out everything, doing a straight restore on top of the original one would have been the best option here. Then the logs should replay in to the database to deal with the changes.

However the best option may well have been to simply call Microsoft support and get them to do the restore for you. Yes it will cost, but it will be done right. When it comes to data recovery, the best chance of a successful recovery is to use support early as you can.

Just follow the instructions under option 3 (Recover folders via public folder database restore):

Hi Sembee2!

I'm not too sure if its an exchange aware backup :(
I basically used a Veeam backup image to restore just the .edb file.

When you say a straight restore on top of the original, can you explain further on this?
Can i just overwrite the current bad .edb with the restored copy? Would that work?

Hi NetoMeter,

Thanks for the link! That will require exporting to PST from outlook and then importing it again.. which is unfortunately what i'm doing already (using a 3rd party software instead - Kernel for Exchange)

Thanks guys for your replies.
I've screwed up my otherwise trouble-free weekend with this moment of stupidity :(

I am not familar with the Veeam software so cannot comment on whether it is Exchange aware or not. You would need to do an Exchange aware recovery, not a restore of the raw file on top of the original. That is unlikely to work. Exchange isn't designed to be backed up via the raw file method.
