This week I was reviewing the recovery software for Exchange environment & I can say that “Kernel for Exchange Server Recovery” is one of the best /economical software.
By using this software you can extract PST from edb database, save it to Exchange/o365, save it to Public folder/ Archive mailbox.
I have tested the SAVE it to PST option & it works like a charm, This software can also be used in the environment where you take backup of exchange using Snapshot technology & than you can use snapshot restore /extract the PST from edb to restore the particular mailbox.
Installation/Configuration is quite simple, I just grabbed the binary file of the software which was just 17.7 MB in size & started installation.
Here are the Step by step instructions along with screen shots(OS I have chosen is windows 2008 R2)
Click Next to follow the Wizard
Accept the License Agreement to move further
Select the installation path or just click next to choose the default location.
Click Next
Follow the wizard further
Click Finish & launch the Kernel for Exchange Recovery.
Now enter the activation details:
I received the below error because outlook was not installed on the system so I installed outlook 2010.
After outlook 2010 installation , I have launched the software again & this time there were no errors, select the EDB file from which you want to extract user PST.
I just followed the standard option as recommended.
After you will click finish you will be able to see all mailboxes inside the EDB file.
Now just click save to PST option & select the mailbox that you want to convert to PST file.
Follow the wizard & pst will be restored.
You can also check the HTML report on how many items were restored specific to particular folder.
Software is very simple & also have very simple Licensing requirements that you can find on below link: (prices are also not high)

There are three different types of Licenses:
Corporate License As the name suggests its for the single orgnaizations but they can install it on multiple machines.
Corporate License (Premium) with premium verison you get 24*7 support as well as added benefit of migrating data to office 365.
Technician License This is for IT organizations that take Annual maintenance contracts for other organizations. I think free lancers/Consultants will also benefit from this licensing model but do check with the vendor.
If you are using SAN & still using traditional backup for mailbox recovery/ single item recovery (example : thru backupexec/netbackup), you can get rid of them by implementing snapshot based backup & for restore mechanism just restore the snapshot ,map the LUN to the server where Kernel for Exchange recovery is installed & do a mailbox recovery.
This software supports outlook version from 97 to 2016 & exchange version from 5.0 to 2016. It is gold award winner from popular msexchange.org
Apart from Kernel for Exchange Recovery there is Kernel Exchange Suite as well, which includes OST to PST, PST & Bkf repair in addition to EDB recovery, I did’t got the chance to explore the other parts of the Suite but as I have worked thru EDB recovery so I can easily say that other recovery tools in the suite would be similar (simpler in installation, configuration & working).

Thank you very much for your detailed review, it was very interesting and informative.
I have tried both Kernel for Exchange Server Recovery and Stellar Phoenix Mailbox Recovery and really liked the feature in Stellar Phoenix Mailbox Exchange Recovery in which one can even perform recovery of deleted mailboxes. Once I was having trouble using the software so I called the Tech support for help, the tech support solved my queries very cordially.
All in all I’m very satisfied with Stellar Phoenix Mailbox Exchange Recovery.
Just took a trial of Kernel exchange database recovery and compared with Shoviv exchange recovery manager. When it comes to technical support, Shoviv exchange recovery manager always wins. They have excellent technical support team which always ready to provide instant support even for evaluation version too.
