Product Overview

Stellar Repair for Exchange is a Windows app that fixes and recovers data from damaged, dismounted, or offline Exchange Server EDB files. It supports many Exchange versions. This includes older systems like Exchange 5.5 and 2000. It also covers the latest Subscription Edition (SE), as well as the 2019 and 2016 editions. Backward compatibility helps organizations with hybrid or transitional environments. It ensures that no data gets lost because of version mismatches.

Exchange Recovery software uses advanced scanning algorithms. Quick Scan performs fast, surface-level repairs. Extensive Scan offers deeper, more thorough recovery. It extracts emails, contacts, calendars, tasks, notes, attachments, and public folders. Plus, it keeps the original folder hierarchy and structure intact. Stellar Repair for Exchange keeps your data intact, unlike brute-force methods that may scramble it. This means recovered items are ready to use in Outlook or can be easily re-imported to live servers.

The tool comes in three editions to suit varying needs:

Corporate Edition ($399, down from $599): Perfect for small to mid-sized teams. It repairs up to 100 mailboxes and exports to PST, live Exchange, or Office 365.

Technician Edition ($599, down from $799): This is the top choice for pros. It includes unlimited mailbox repairs and all Corporate features.

Toolkit Edition ($999, down from $1,999): This 5-in-1 suite combines EDB repair, EDB to PST conversion, OST extraction, mailbox backup extraction, and Windows Server password reset. It’s ideal for complete admin workflows.

Installation is easy: Download the free trial from the Stellar website. You can scan and preview with no file size limits. However, saving files needs a license. Runs on 64-bit Windows 11, 10, 8.1, or Servers 2022, 2019, 2016, and 2012. It needs minimal resources: at least 8GB RAM, with 16GB recommended. Also, it integrates smoothly with Azure AD for Office 365 exports. It’s not just a repair tool. It’s a complete recovery system that reduces the chaos of Exchange failures.

Key Features: A Deep Dive

Stellar Repair for Exchange stands out because of its range of features. Each one is designed to address specific challenges in Exchange recovery. Let’s break them down.

Exchange Database Recovery with Dual Scan Modes

The main feature uses strong algorithms to scan and fix EDB files. It can handle files in a “dirty shutdown” state. This often happens due to sudden power loss or deleted transaction logs, leading to unmountable databases. Quick Scan quickly fixes mild corruption, often in minutes for smaller files. Extensive Scan goes deeper for severe cases and can recover up to 99% of data in tests on large, multi-GB EDBs. Users can preview items in a tree-view layout like Outlook. This way, they avoid surprises when exporting. This dual-mode approach changes the game. Native tools, like Eseutil’s /p (hard repair), can lead to data loss. However, Stellar Repair for Exchange repairs EDB file without causing that issue.

Public Folders and Archive Mailbox Recovery

Public folders are often ignored but are important for shared resources. They can be fully recovered. You can export them to PST or upload them directly to live Exchange or Office 365. Archive mailboxes, crucial for compliance, are supported too, saving in multiple formats (PST, MSG, EML, etc.). This feature can help organizations avoid compliance issues. It keeps important metadata, such as timestamps and permissions.

Direct Exports to Live Exchange and Office 365

Downtime is the enemy, and Stellar Repair for Exchange combats it with seamless exports. For live Exchange, enter admin credentials and a CSV of target mailboxes. The tool automatically maps using IDs, but you can manually override if needed. To integrate Office 365, set up Azure AD (App ID, Directory ID, Client Secret). After connecting, it can bulk-export and prioritize queuing. In benchmarks, this cut restoration time by 70% compared to manual PST imports.

Advanced Filtering, Selective Recovery, and Prioritization

Precision is key. Advanced filters can exclude junk or deleted items. They can also narrow results by sender or date. Selective recovery lets users pick specific mailboxes or folders. An intuitive preview makes this easy. Prioritization queues important VIP mailboxes first. Then, parallel processing can handle up to 8 at once, depending on RAM. This speeds up recovery times for large deployments. For eDiscovery, detailed searches by subject, attachment, or importance give exportable results. This makes legal holds easier without needing full restores.

Multi-Format Saves and Unicode Support

Flexibility is important. Save to PST, which auto-splits at 45GB for Outlook. You can also use CSV for contacts. For archiving, choose detailed formats like PDF or RTF. Unicode support lets multilingual EDBs, like non-Latin scripts, recover easily. This is important for global companies.

VM Compatibility, Log Reports, and Large File Handling

Run it on virtual machines (with domain admin rights) for cloud-hybrid setups. Post-recovery, generate detailed logs for audits—faster than Eseutil’s verbose outputs. Large EDBs (terabytes) are easy to handle. It repairs smoothly without crashing, unlike free options that struggle with size.

Toolkit Extras

The full Toolkit offers EDB to PST conversion, skipping repairs for clean files. It also extracts data from inaccessible OST files. This makes it a complete admin suite.

These features aren’t gimmicks; they’re battle-tested. In a test crash with a 50GB EDB missing 30% of logs, Stellar recovered 95% in under 2 hours. This matches user reports on Slashdot.

Real-World Use Cases

Stellar Repair for Exchange shines in critical scenarios:

• Dirty Shutdowns: Rebuilds EDBs without transaction logs, bypassing Eseutil failures.
• Mount Failures: Repairs unmountable databases for quick exports, avoiding full restores.
• DAG Suspensions or Jet Errors: Directly accesses suspended database copies for recovery.
• Post-RecoverServer Crashes: Extracts mailboxes when native tools fail.

Case Studies (2025):

• Cloverleaf Dynamics Limited: Recovered from a dirty shutdown that halted email services. Stellar Toolkit restored operations in hours, earning praise as “invaluable for Exchange hosts.”
• iConnect Consulting: Achieved full folder recovery with customizations intact after a dirty shutdown, lauded for “streamlined DIALTONE integration.”
• Worktrainers Ltd.: Prevented data loss during a Microsoft 365 migration, described as “user-friendly.”

These align with feedback on G2, Trustpilot, and TechGenix, where users highlight its reliability in crisis recovery.
