Kernel for Exchange Server Recovery | Exchange Server

If you work as Exchange Server administrator, sometimes you face certain situations where you have to do a recovery for a mailbox for different reasons as can be hardware failure, recover information or a disaster recovery.

In this opportunity, I want to show you a very useful tool which allows you to export to PST each mailbox which are hosted in our Exchange Server, directly from the database.

The most interesting is that it can work without any exchange services running to perfom a recovery.

What kind of Exchange Database it support?

Kernel for Exchange Server Recovery supports the following Exchange Server versions:

Exchange Server 5.0
Exchange Server 5.5
Exchange Server 2000
Exchange Server 2003
Exchange Server 2007
Exchange Server 2010
Exchange Server 2013

Can it export to PST from corrupt databases?

Yes, this tool can export from corrupt databases and save to PST the mailboxes and folders which are inaccessible. Inclusive, it recovers information from databases in dirty shutdown.

Does it have some size limit to work with databases and mailboxes?

No, It doesn’t. There is no size limit.

What kind of information retrieved the tool?

The tool recovers deleted mailboxes, folders, items and it supports recovery of all attached files. It can be recovered from a single mailbox or in a bulk.

Among the items that it recovers there are emails, attachments, folders, pictures, tasks, notes, reminders, meetings, calendars, deleted among others. All with their respective properties.

How do I use the sofware?

Below, we do a short demonstration of the power of the tool.


• Exchange 2013 Service Pack 1 with a mailbox database and three mailboxes.
• A workstation with Outlook 2013, which we will used to recover the information.


Step 1

First, we have to download the software and install it on a computer which has a Microsoft Outlook installed, in order to recover to PST the mailboxes.

In my case, I will install it on a Windows 8.1 x64.








As you can see, the installation is too simple, just a couple clicks.

The Microsoft Outlook versions supported are:

• 97
• 98
• 2000
• 2002
• 2003
• 2007
• 2010
• 2013

But we know that the only versions supported by Microsoft are:

• 2007 with latest updates
• 2010 with latest updates
• 2013

Step 2

In this example we will perform a recovery from one mailbox which has emails items, contacts and an appointment.

Let’s take a look.




Now, we will move my corrupt Exchange Server database which I will try to save to PST.

The database will be copied to my Windows 8.1 workstation, which has Outlook 2013 and Kernel for Exchange Recovery installed.

Step 3

Once we have moved the database, we have to execute Kernel for Exchange Recovery.

Step 4

In order to save the mailbox to PST, we have to click the option “select EDB…” from the ribbon.


Then, we select the database which we want to perform recovery and click on Next.


We have to choice between two options:

• Standard Scan (Fast and Recommended)
• Advanced Scan (Recommended for severely corrupted databases)

In our case, we will select Standard Scan.


Step 5

Once the scan finished, we will be able to browse the mailboxes which were hosted on the database.



Step 6

Now, only remains select the mailbox that we will save to PST.

As you can see in the following picture, you can exclude or select any folder from the mailbox.


Step 7

Done! Once we have selected a path to save the PST file, Kernel for Exchange Server will perform the recovery!!


Step 8

If we open the PST file with an Outlook, we will see all the recovered items!

This tool is an excellent option to perform a recovery from our EDB databases, because it can recover any mailbox in a single or bulk process and the most important point is that it can perform a recovery from corrupted databases.

On the other hand, you don’t need any Exchange Server services to perform a recovery and save the information to PST.

That is a excellent advantage which can help us to face any situation of loss information.
