What are the main benefits of Stellar Repair for Exchange?

Stellar Repair for Exchange is a Windows tool for corrupt, dismounted, or dirty shutdown Exchange database (.edb) files. It extracts mailboxes, archive mailboxes, and public folders from the offline database and saves them to PST or directly into a live Exchange Server or Microsoft 365 mailbox.

Avoids Eseutil Risk – Runs on a copy, leaving originals untouched.
Faster Mail Restore – Set mailbox priority and process several in parallel.
Selective Recovery – Restore single items instead of entire databases.
Cloud Migration Path – Move legacy EDB data straight into Microsoft 365.
Audit Log Report – Documents each recovery run for compliance review.
Resumable Scans – Save scan results and continue the repair later.

What does Stellar Repair for Exchange do?

It repairs offline Exchange database files that no longer mount, typically after a dirty shutdown, missing or purged transaction logs, or a failed server. The software scans the .edb with Quick Scan or Extensive Scan, rebuilds the folder hierarchy, and displays every recoverable item in a three-pane preview before anything is written. Recovered data can be saved as PST or exported directly to a live Exchange Server or Microsoft 365, while individual items can also be saved as MSG, EML, RTF, HTML, or PDF. The tool never writes to the production database: you copy the corrupt EDB to another location and scan that copy.

Who is Stellar Repair for Exchange best suited for?

It fits Exchange administrators who are facing an unmountable database and have no usable backup, which is the exact point where Eseutil hard repair becomes a gamble. Support providers use it during decommissioning projects, because it opens an EDB from a server that no longer exists and pushes those mailboxes into Microsoft 365 without PowerShell export requests. It also helps in legal or HR requests, where only one mailbox or a single message thread has to be pulled out of an old database rather than the whole store. Version support runs from Exchange 5.5 through Exchange 2019, so archived databases from long-retired servers remain readable.

Which Exchange versions and platforms are supported?

The software reads EDB files from Exchange Server 2019, 2016, 2013, 2010, 2007, 2003, 2000, and 5.5. It is a 64-bit Windows application and runs on Windows 11, 10, 8.1, and 8, as well as Windows Server 2022, 2019, 2016, and 2012; there is no macOS or Linux build. For direct export to a live server or Microsoft 365, a configured Outlook profile with sufficient mailbox rights is required, and Stellar supplies a server console executable to grant full access to disconnected mailboxes. Since Microsoft ended support for Exchange 2016 and 2019 on 14 October 2025, many buyers use it as the extraction step of a move to Exchange Server SE or Microsoft 365.

What technical limitations should users know before buying?

This is a repair and extraction tool, not backup software: it has no scheduling, no continuous protection, and no image-based restore. It works on an offline or dismounted EDB file, so it cannot connect to Exchange Online and repair a hosted mailbox in place. The Corporate edition stops at 100 mailboxes, which matters if the database you are repairing holds more, and OST conversion, BKF backup extraction, and Windows Server password reset are only present in the Toolkit bundle. Extensive Scan on a multi-gigabyte database can run for hours, which is why the scan result can be saved and reloaded instead of repeated.

What is the difference between the Corporate, Technician, and Toolkit editions?

The repair engine is identical in all three; the difference is mailbox volume and the extra utilities bundled alongside. Corporate covers up to 100 mailboxes, Technician removes that limit, and Toolkit adds four separate applications for EDB conversion, Exchange backup extraction, OST conversion, and Windows Server password recovery. Choose Technician when a single database exceeds 100 mailboxes, and Toolkit when you also have to handle orphaned OST files or a corrupt BKF backup set.

How does it compare to running Eseutil on a corrupt database?

Eseutil /p performs a hard repair directly against the production database and discards pages it cannot read, with no preview of what will be lost. Stellar Repair for Exchange scans a copy of the EDB, then lets you inspect mails, calendar entries, contacts, and attachments in the preview pane before you commit to saving anything. It is also the practical route when transaction logs are missing or deleted, since it does not depend on log replay to reach a clean state. Both approaches still require enough free disk space and a copy of the database, so plan the working directory before starting a large scan.

Frequently asked questions about Stellar Repair for Exchange

Does the software change the original Exchange database?

No. Stellar recommends copying the corrupt database to a separate location and scanning that copy, so the source EDB stays untouched. The software also produces a log report of the recovery run, including recovered folder details, timestamps, and the EDB path, which is useful for incident documentation.

Can a long scan be paused and continued later?

Yes. Scan results can be saved as a scan information file and reloaded afterwards, so an interrupted Extensive Scan does not have to start from zero. This matters on large databases where a full deep scan can take hours and a maintenance window may end before saving is finished.

Does it recover deleted mailboxes and public folders?

Yes. It recovers deleted and disconnected user mailboxes, shared mailboxes, archive mailboxes, and public folders from the EDB, alongside mails, attachments, contacts, calendars, tasks, notes, and journals. Recovered public folders can be exported to PST or written back to a live Exchange Server or Microsoft 365.

What can the free trial version actually do?

The trial scans the corrupt EDB file and previews every recoverable mailbox and item, but it does not save or export the recovered data. That makes it a reliable pre-purchase test: if an item appears in the preview pane, it can be recovered by the full version.
