In an earlier version of Exchange Server like Microsoft Exchange 2007, there were storage groups where the user mailboxes were saved. You could easily create a backup for storage groups and keep them. But after Microsoft Exchange 2010, the storage group were replaced with databases, that’s why it becomes complicated to maintain a brick-level backup of Exchange data.

To solve, the backup issue, Microsoft has issued some other methods in the Exchange framework by which you can convert the EDB files to a PST format for backup purposes.

EDB vs PST File

EDB – An Exchange database (EDB) file stores the multiple user mailboxes created in the Exchange Server. There can be multiple Exchange database files in a single Exchange Server.

PST – A PST file is a container where the Outlook messages and other mailbox items are saved. It is created by default as soon as you create an Outlook profile.

More about EDB files

Exchange Database (EDB) file is the root file that contains user mailboxes including the folders saved as a B-tree structure.

Priv.edb: it is the EDB file created to save the primary mailboxes. There can be multiple mailboxes in a single EDB file.

Pub.edb: it is the EDB file that saves all the information in the public folder in earlier versions of Exchange.

STM files: STM files reduces the size of the EDB file by keeping the attachments separate from the email messages.

Important information about the EDB files

• To store and retrieve the data from the EDB file, Exchange Server employs Extensible Storage Engine that is also known as the JET Blue engine.
• There are in-built utilities in the Exchange Server like ESEUTIL and ISINTEG that can repair the EDB file for the minor corruptions.
• You can directly export the contents from the EDB files to a PST file by using the New-MailboxExportRequest cmdlets.

Reasons for EDB to PST Conversion

There can be multiple reasons behind an EDB to PST conversion, and some of them are following –

• EDB file has become corrupt, and you want to recover its data
• To reduce mailbox size and to improve server performance
• To save storage space (and avoid extra expenditure on infrastructure)
• Need to backup Exchange mailboxes
• Need to backup some specific mailboxes or emails
• Want to port some mailbox data to another place
• To retain data for legal or compliance requirements
• To reduce the chances of EDB file corruption & Jet errors

There are a few manual methods and one automated tool-based method to convert EDB to PST.

• Convert EDB to PST using the ExMerge Tool
• Convert EDB to PST using Exchange Management Shell commands
• Convert EDB to PST using Exchange Admin Center
• Convert EDB to PST file Using the Free Tool

Convert EDB to PST Using ExMerge Tool

The ExMerge tool will copy the Exchange items to a PST file, which you can later place in the destination Exchange Server. The ability of the ExMerge tool to merge the content of the Exchange data makes it a useful tool for Exchange to PST conversion. However, this method is not useful now as it supports only the older versions of Exchange.

Convert EDB to PST Using Exchange Management Shell

Exchange Management Shell provides a command line interface to access the database, get its status, and make the required changes in them.

To convert free EDB to PST file, use the following commands in a sequential manner

1. Run the command to get the list of mailboxes in a database.
   Get-MailboxStatistics -Database <DatabaseName>

   The command will enlist all the mailboxes present in the database.

2. Run the command to export the EDB file to a PST.
   New-MailboxExportRequest -Mailbox <MailboxName> -FilePath \\ExchangeBackup\PST\MailboxName.PST

   The command will save the mailbox data to a new PST file. But make sure that the destination folder is a shared folder.

3. Run the command to check the status of mailbox export request.
   Get-MailboxExportRequest

   It will provide the status of the export request.

4. After completing the export process, cancel the export request by the following command.
   Remove-MailboxExportRequest -Identity <Name of the export request>

Using this process, you can export the data from a single mailbox.

Convert EDB to PST Using Exchange Admin Center

This is the most direct method to export an EDB file to a PST file. Here is the process:

1. Log in to Exchange Admin Center as an administrator.
2. Go to the permissions tab and then click admin roles.
   
3. Under admin roles, go to Recipient Management and click (+).
   
4. Under the Role Group wizard, click the (+) option under the Roles option.
   
5. Select the Mailbox Import Export Role and click the add button. Then click OK.
   
6. Now you can see the Mailbox Import Export role under Recipient Management.
   
7. Now, go to recipients, select mailboxes, and choose any mailbox you wish to export. Then, click more (•••) and select the option Export to a PST file.
   
8. Browse a mailbox which you want to export.
   
9. Provide the path of a shared folder.
   
10. Select a mailbox which will get an email after successful conversion. Finally, click Finish. The mailbox content will be migrated to the PST file.
    

So, these are the two manual methods which can help in free EDB to PST conversion directly. But you can understand that they are quite complex, especially for busy Exchange administrators who may not get enough time to manage EDB to PST conversion. So, these methods are not suitable for them.
