System Requirements



Use Cases

Recovery for Exchange Server allows users to repair EDB files that cannot be mounted to server because of email database corruption.

Exchange EDB repair is done in the following easy steps:

Formerly known as Exchange Recovery, EDB repair utility has been renamed to Recovery for Exchange Server. After initial processing of corrupted EDB, Exchange Recovery allowed to select only entire mailboxes to extract. The new version provides the capability to browse and repair individual folders and messages within mailboxes.

EDB repair software can be used in situations when Exchange EDB repair is necessitated by email database corruption due to the so called "dirty shutdown". To repair Exchange EDB quickly, the database file should be placed on a local drive. It is important to note that using EDB repair tool over a network can have significant adverse effect on performance. EDB repair software performs multiple resource-intensive operations, thus requiring good disk drive throughput and short access times.

EDB to PST Converter

Recovery for Exchange Server is capable of performing EDB to PST conversion on both healthy and corrupted email databases. EDB-PST converter has many applications in the course of Exchange Server management. When converting Exchange EDB to PST with Recovery for Exchange Server, it is possible to select folders to be exported.

While databases can be as large as hundreds of gigabytes in case of Exchange EDB, PST files are typically much smaller than that. To extract PST from EDB, a subset of email messages must be selected. When this is done, press the Save button on the toolbar, and Recovery for Exchange Server will repair EDB to PST.

A common reason to export EDB to PST is migrating part of an Exchange email database to Outlook. Another incentive to export PST from EDB is extracting important emails from a damaged Exchange store that cannot be attached to server.

How to Repair Mailbox from EDB

To extract mailbox from EDB, user marks it for export in the email database items tree shown in Recovery for Exchange Server user interface. Additional items from other mailboxes can be selective added as well. If needed, user can proceed to extract mailboxes from EDB file on a mass scale by either marking for export the root of the items tree or selecting a set of specific mailboxes from list.

Questions And Answers

Q: Can Recovery for Exchange Server repair my Exchange Server email database?
A: The effective way to find out if a Exchange Server email database is recoverable is to try the demo version of Recovery for Exchange Server on it. Visit the Demo page for a free copy of the demo.

Product specifications with lists of items recovered and not recovered is available at the Product Information page.

Note: Always backup your original corrupted Exchange Server email database before proceeding with any repair activity!

Q: What limitations does the demo version of Recovery for Exchange Server have?
A: The demo version repairs only several messages per mailbox from the corrupted email database. The others are left blank. File attachments (if any) are not recovered.

If due to file damage an entire object (such as a folder) has been lost, the full version of Recovery for Exchange Server will not be able to repair it.

Q: I have tried the demo. How do I decide whether to purchase the full version of Recovery for Exchange Server?
A: Evaluating the results of demo repair can help in making the decision.

Q: What are the differences between product licenses?
A: Details of current licensing scheme are described at the Licensing page.

Q: Why do results of repair contain less data than the original Exchange Server email database?
A: This is normal. The damaged parts of your Exchange Server email database will convert to zero size on output. The other common reason of file size decrease is when some of features of the original email database are not supported and therefore absent from the recovered email database.
Demo-recovered email database is smaller because it mostly consists of demo placeholders than actual data.
Q: Running Recovery for Exchange Server from command line (through Windows Start -> Run menu).
A: If your license type is Enterprise or Service, you can run Recovery for Exchange Server from command line and use these calls in your batch files. Standard version does not support command line. The format for command line call is:

esr.exe <original filename with path> "<path to directory to store the recovered file(s)>"
(without angle brackets).

Please note that the directory for recovered file(s) should be created before starting the repair.

Command line mode supports patterns '*' (replaces group of symbols) and '?' (replaces one symbol).

Q: I am running Recovery for Exchange Server for several hours now, but have not yet received any results. Is there a problem?
A: The repair procedure is a relatively time-consuming process, which depends strongly on the original email database corruption range, CPU power and RAM amount (1GB+ recommended). For big files it might take several hours or even days to proceed.

It is recommended to run the Recovery for Exchange Server in a logged mode. You can monitor the status of the process with the help of log file: if it is being updated constantly, the file is being processed. If, vice versa, there's no activity registered for more than 5-10 minutes, the software might be caught in loop. In this case, please, contact our support team for further instructions.

To create log file, please hold the SHIFT key while clicking the Repair button on the toolbar or selecting the Repair: item in the main menu. You can also press CTRL+SHIFT+R after launching the program.

Q: Several .PST files and a new directory called 'M' have been created as after running Recovery for Exchange Server. What is the purpose of these?
A: The repair results are stored in several different ways depending on the Exchange Server database type being recovered.

If the personal mailboxes are being recovered, Recovery for Exchange Server creates several folders, one per mail user, and stores the personal mail there in the standard .PST file.

If the recovered .PST file size exceeds the 1,5Gb limit it is being split into several independent .PST files named subsequently (e.g., admin.pst, admin1.pst, admin2.pst, etc.).

If the Exchange Server database with public folders is being recovered, Recovery for Exchange Server recreates in folder \M\ the whole database hierarchy folder structure. The recovered items from public folders are saved as standard .MSG files.

Q: What is the procedure for recreating email database using .PST files and the 'M' directory?
A: To import data from .PST files, use the free Exmerge utility by Microsoft:

To move data from 'M' folder to the Public Directory, do the following:

  • Connect to any of the Exchange Server mailboxes using Microsoft Outlook
  • After being connected, you get access to the public folders. Drug-and-drop items from 'M' folder into the appropriate public directory of the email database
