Comprehensive Guide to Exchange Server Database Recovery

8 Min. Read

In the realm of data management, Exchange Server plays a pivotal role in facilitating efficient communication and collaboration within organizations. However, unforeseen circumstances can lead to data loss, corruption, or server crashes, putting critical information at risk. When faced with such situations, it’s imperative to have a robust Exchange Server Database (EDB) recovery strategy in place.

Are you struggling with damaged or corrupt Microsoft Exchange database files? In this comprehensive guide, we’ll delve into Exchange Server Database recovery’s intricacies, providing insights and solutions to tackle these challenges effectively.

Understanding Exchange Server Database Files

Before delving into the recovery process, it’s essential to grasp the fundamentals of Exchange Server Database (EDB) files. An EDB file, short for Exchange Database, is a repository of mailbox data, including emails, contacts, calendars, and more. It serves as the backbone of Microsoft Exchange Server, storing and organizing user data.

There are many common causes that could lead to EDB data loss:

Hardware Failures

Hardware failures, such as disk crashes or storage system malfunctions, can lead to EDB file corruption and data loss. These issues can strike unexpectedly, making it crucial to have a proactive recovery plan.

Software Corruption

Software glitches, server crashes, or improper shutdowns can corrupt EDB files, rendering them inaccessible. Identifying the root cause is the first step in devising a successful recovery strategy.

Human Error

Accidental deletion of mailboxes or emails by users can result in data loss. Having mechanisms in place to recover from such errors is vital for maintaining data integrity.

EDB Recovery Solutions

One the primary methods for EDB recovery involves repairing the Exchange Database (EDB) file, and exporting the recovery data to PST, Live Exchange, or Microsoft/Office 365.

Numerous EDB repair tools are available in the market, designed to scan and repair corrupted EDB files. These tools can often restore mailbox data and fix corruption issues, but their effectiveness may vary.

For critical EDB recovery scenarios, seeking professional recovery services from experts in the field is a prudent choice. These professionals employ advanced techniques and tools to recover data from severely damaged EDB files.

However, if you want to change the default path of the Temp path, you can click the ellipses (...) in front of Temp path field to browse the desired location.

Please note that you can add multiple files, but only one file can be scanned and repaired at a time.

5) After selecting the EDB files that you want to repair, click Next. Select Scan Mode dialog box opens. There are two ways to scan the files depending upon the level of corruption to your EDB files. You can select either Quick Scan or Extensive Scan.

Select Scan Mode
Select Scan Mode

If you want to quickly scan the corrupt EDB file, select Quick Scan, which is a fast mode to scan and repair corrupt EDB file. Or, if you want to scan the corrupt EDB file deeply for better results, select Extensive Scan. Click OK to start the scanning process.

Tip: Quick Scan takes less time in scanning process and provides a standard scan of your EDB files. Use this mode if you are scanning the EDB files for the first time. After scanning, preview the results and if you are not satisfied with the Quick Scan mode, then you can try Extensive Scan mode. Extensive Scan mode of scanning an EDB file is slow but more effective process. This mode is more powerful than Quick Scan mode. It is able to repair even highly corrupted EDB files.

6) Once scanning is complete, you can preview the data of the scanned EDB file. As shown in the figure below, you will find a navigation tree on the left side showing the files with its mailboxes, folders and sub-folders. You can select the desired mailbox/folder/sub-folder from this pane to view its data. In this example, the Preview data is obscured for obvious reasons.

You can change the order of any given columns as per your requirement. You can sort columns and do a quick search.

7) At any point in time, you can click on Save Scan from the Home ribbon and create a file containing all the information related to the scanning process of the scanned EDB file. Using this scan information file, you can resume the process (Load Scan) at a later stage without having the need to scan the Exchange Server Database (EDB) file again. This saves a lot of scanning time especially when you have large EDB file or performing an Extensive scan.

8) Once the Exchange Server Database file is repaired, you can export/save the data into various formats:

  • You can export Mailbox to Live Exchange Server.
  • You can export Mailbox to Office 365.
  • You can save Mailbox in PST Format.
  • You can export Mailbox to Public Folder.
  • You can save Mailbox in MSG, EML, RTF, PDF or HTML formats.

In this example, we will export the repaired mailboxes to Microsoft/Office 365 mail accounts. The software provides a mapping feature that ensures the source mailbox is exported to the correct destination mailbox. You can export Multiple Mailboxes or Single Mailbox to Office 365. Before you start the process, make sure to configure the Outlook Profile of the user with Administrator rights.

9) Right click on the mailbox that you want to export from the navigation tree as shown in the figure below, and select Export to Office365 to save the mailbox in Office 365.

Stellar Repair for Exchange also provides options to either Auto-Map or Manually Map the source mailbox from the scanned EDB file to the destination mailbox on Office 365.

Mapping is a process to link a mailbox from your source EDB file to a mailbox that already exists on the destination server before exporting the data. The mapping process is required to make sure that the mailbox data from the EDB file is exported to the desired mailbox on the Office 365.

11) After entering the credentials on the Enter Login Credentials window as shown in Step 10, the Map Mailboxes dialog box appears. This dialog box can be used for functions such as setting priority to export the mailbox data, map source mailboxes to desired destination mailboxes, applying a filter for exporting the data, etc.

You can take the mouse cursor to the particular column name in Map Mailboxes window to get brief information about that particular column. The information is displayed in a tooltip as shown in the figure below.

The Map Mailboxes dialog window consists of the following column options:

> Selection: This column provides checkboxes to select or unselect a mailbox to export. By default, all the checkboxes are selected, you can uncheck the checkbox for the mailboxes that you do not want to export.

> Priority: When exporting mailboxes from source EDB files, it is often necessary to prioritize certain mailboxes over others. The software follows a FCFS (First Come First Serve) process, where the mailbox that appears first in the “Mailbox from your EDB (Source)” column is given the highest priority and is exported first. By default, the mailboxes are sorted alphabetically and exported to the Office 365 server in that order. However, using the “Priority” column, you can sort the mailboxes according to your preference and ensure that important mailboxes are exported before others.

> Mailbox from your EDB [Source]: This column provides the list of mailboxes from the scanned EDB file that you have selected from the preview screen for export. By default, the mailboxes are alphabetically sorted. The column also provides a search box that can be used to search for a specific mailbox from the list.

> Office 365 Mailbox [Destination]: After the mailboxes are mapped, this column provides the corresponding destination mailbox where the data of the mailbox from the Source EDB file will be exported. The column also provides a search box that can be used to search for a specific mailbox from the list.

> Mailbox Mapping Status: The Mailbox Mapping Status column shows whether the destination mailbox has been assigned to the source mailbox or not. If the data is being exported from the source EDB file to a destination mailbox, the column displays “Mapped”. If the destination mailbox has not been assigned, the column will show “Not Mapped”. Additionally, you can use the search box provided in the column to find mapped or not mapped mailboxes.

> Edit: In this column, you can assign or change the Office 365 Mailbox (Destination) mailbox that is linked to the Mailbox from your EDB (Source). To do this, simply click on the Edit icon and a Map Destination Mailbox dialog box will appear. This dialog box displays information about the existing mailboxes of users on the Office 365 server. From here, you can select the destination mailbox where you would like to export the data from your EDB Mailbox (Source).

> Apply Filter: You can use this option to filter the repaired mailboxes that you wish to save or export. The Apply Filter option lets you customize the scanned results to meet your specific needs. You have the option to exclude Junk Mails and Deleted Mails, set filters to save data from a specific month, date, or year, and even exclude one or more senders from the results.

There you have it… Happy Exchange Server Database Recovery!
