Stellar Converter for EDB Corporate: Export Exchange Mailboxes Without the Exchange Server
Stellar Converter for EDB Corporate is a $299 one-year Windows program that opens an Exchange database (EDB) file, from a decommissioned server or a running one, and exports its mailboxes, archives and public folders to PST files, a live Exchange Server or Microsoft 365. It suits admins and consultants migrating or archiving up to 50 mailboxes, and the free trial previews every mailbox before you pay.
Exchange's own export, New-MailboxExportRequest, only works on a mounted database on a working server, and it can't export public folders. An EDB copied off an old server, or left behind after a migration, is otherwise just a big file nobody can open. This tool reads it directly, with no Exchange Server or Active Directory needed.

- Count mailboxes. Corporate covers 50. Technician covers 500 for $399, and the Toolkit is unlimited.
- Preview first. Stellar doesn't refund purchases made without trying the trial, and renewals aren't refundable.

Overview
On launch, Stellar Converter for EDB asks one question: Hosted Exchange or Offline EDB. Hosted mode connects to a running server and exports mailboxes without dismounting the database or interrupting users. Offline mode opens an EDB file on disk. Either way you end up in an Outlook-style window with mailboxes on the left, messages in the middle and a preview on the right, and you pick what to export and where.
The start screen: convert from a hosted Exchange server or from an offline EDB file.
Features
Opens old EDB files without Exchange
Stellar Converter for EDB reads offline EDB files from Exchange 5.5 up to SE without an Exchange Server or Active Directory, which database portability and a recovery database can't do for an old file. It handles Unicode EDBs, so mail in any language comes through.
An opened EDB: mailbox folders on the left, messages in the middle, the selected message on the right.
Exports straight into Exchange or Microsoft 365
Stellar Converter for EDB exports mailboxes to a live Exchange Server or a Microsoft 365 tenant, mapping them automatically by email ID with a manual override. It can also send converted mail into public folders or the in-place archive. Incremental export copies only what's missing on a re-run, so you don't get duplicates.
The export choices: Exchange Server (live, archive or public folder), Microsoft 365, PST or other formats.
Public folders and archive mailboxes
Stellar Converter for EDB exports public folders to PST, live Exchange or Microsoft 365, something Exchange's own PST export can't do, and converts archive mailboxes too.
Eight mailboxes at once, in your order
Stellar Converter for EDB processes up to eight mailboxes in parallel and lets you set a priority queue, so the most important users migrate first. PSTs over about 45 GB are split automatically.
Mapping EDB mailboxes to destination mailboxes, with priorities; unmapped ones are flagged.
Search, filters and contacts
Stellar Converter for EDB searches by To, From, Cc, Subject, Body, attachment name, importance and item type, filters out Junk, Deleted Items, chosen senders or dates, and exports all contacts, including the Global Address List, to CSV. A saved scan can be reloaded later instead of rescanning a large EDB.
Benefits
It turns a dead server's database into something useful in an afternoon. Instead of rebuilding an old Exchange version just to read its mail, you open the EDB on any Windows PC and push the mailboxes into Microsoft 365. For a live server, the hosted mode lets you take PST archives of departing users or a whole department without downtime.
Real-World Uses
- Moving a small company to Microsoft 365: export 30 mailboxes from the old EDB straight into the new tenant, most important first.
- Archiving a decommissioned server: turn every mailbox into a PST before the hardware goes.
- Legal or HR request: search an old EDB for one person's mail in a date range and save it as PDF.
- Public folders nobody can export: move them to Microsoft 365 public folders or a PST.
Who It's For, and Who Should Skip It
Corporate fits small and mid-size businesses, and consultants doing one migration, with up to 50 mailboxes.
Skip it if your database is corrupt or won't mount: buy Stellar Repair for Exchange instead. Skip Corporate if you have more than 50 mailboxes (Technician covers 500) or do migrations for many clients. If the database is mounted and healthy and you only need a few PSTs, New-MailboxExportRequest is free. And for a straight server-to-server or tenant-to-tenant move, Stellar's separate Migrator for Exchange is designed for that job.
Usage Guide
- Install the trial on a 64-bit Windows PC or server with at least 8 GB of RAM. For hosted mode or export to live Exchange, use a machine on the Exchange domain with admin rights.
- Choose Offline EDB and browse to the file (or Hosted Exchange and enter the server credentials).
- Let it scan, then check the mailboxes and items in the preview.
- Buy and activate the license.
- Select mailboxes, click Save, and choose PST, Exchange Server, Microsoft 365 or another format.
- For server exports, upload the CSV of destination mailboxes, check the mapping and priorities, apply any filters and start.
Where it falls short
- Not a repair tool. Several Trustpilot complaints are from buyers who needed a database to mount again; this product doesn't do that.
- Stability on some files. An older Trustpilot review said the converter "crashed on every recovery run". The trial on your own EDB is the test.
- Hosted mode needs permissions. To list disconnected mailboxes you first run Stellar's ServerConsole.exe to grant full mailbox rights.
- Mailbox caps. 50 in Corporate is easy to outgrow mid-project.
What Users Say
Buyers who use it for its real job, exporting mailboxes, are happy; most one-star reviews are about repairs. Stellar as a company scored 4.8 out of 5 on Trustpilot from about 5,600 reviews when we looked, across all products (read through a summarizer, since Trustpilot blocks direct downloads). Independent hands-on reviews of this product are scarce, so we've leaned on users.
Trustpilot: it did the job
Chuck Colley (October 7, 2021, 5 stars): "Stellar Converter for edb software is invaluable to us!"
Steven Carter (December 12, 2017, 5 stars): "I purchased Stellar edb to PST for a mass migration at my company."
Lance Warren (December 5, 2017, 4 stars): "We were able to use the product to extract the mailbox data direct from the edb files."
Martijn Jager (July 23, 2020, 4 stars): "Stellar Converter for edb had no problem recovering the data from the same restored Exchange Mail Store."
Jeff (July 10, 2025, 5 stars): "Nikhil was able to assist me to expediently resolve the problems being experienced in exporting the maiboxes".
Trustpilot: the complaints
Barnd (November 23, 2016, 1 star): "Their edb Converter crashed on every recovery run (stellar support got screenshot)".
Michael (October 4, 2022, 1 star): "Purchased the edb recovery tool, quickly found out it didn't do what we needed it to do".
Leo Fabiani (September 12, 2024, 1 star), on Stellar's repair claims: "fix and recover corruption of edb file and solve most of the mount failures" is not true.
Admins quoted by Stellar
Ratish Nair described it as usable as an "Exmerge on steroids" tool "to allow mass exports from the existing environment to PST or other formats, without bringing the environment offline."
4sysops, as quoted on Stellar's page: "I found Stellar Converter for EDB incredibly easy to install and use—it let me quickly search emails, and export them in multiple formats."
The themes: it's valued for migrations and archives, with support engineers often credited for getting exports through. The criticism clusters around buyers who expected database repair, and some older stability complaints.
Comparisons
Stellar Converter for EDB vs New-MailboxExportRequest
The PowerShell cmdlet is free but needs a mounted database on a working server, the Mailbox Import Export role, and it doesn't do public folders. Stellar works on an offline file, exports public folders and goes straight to Microsoft 365.
Converter for EDB vs Repair for Exchange
Both open EDB files and export to the same places. The converter expects a healthy database; Repair for Exchange is built to scan a corrupt or dismounted one. If you're not sure your EDB is healthy, the Toolkit for Exchange includes both.
Editions and Pricing

FAQs
Does Stellar Converter for EDB need Exchange installed?
Stellar Converter for EDB doesn't need Exchange or Active Directory to open an offline EDB. You need access to a live server only for hosted mode or to export directly into Exchange.

What counts toward the 50-mailbox limit in Stellar Converter for EDB Corporate?

Can Stellar Converter for EDB move mailboxes into Microsoft 365?
Stellar Converter for EDB exports to Microsoft 365 through automatic registration with Azure credentials, or a manually registered Entra ID app (client ID, tenant ID and secret), and maps mailboxes by email ID.
Will the free trial of Stellar Converter for EDB save any mail?
Stellar Converter for EDB's trial scans and previews every mailbox but saves nothing. Saving to PST and exporting to a server need a license.

Conclusion
Stellar Converter for EDB Corporate is worth $299 if you have a healthy EDB, from an old server or a live one, and up to 50 mailboxes to move into PSTs, a new Exchange server or Microsoft 365. The one reason to buy it is that it opens the database with no Exchange in sight and handles public folders, which Microsoft's tools won't. The main reason not to is a damaged database: this converts, it doesn't repair, so buy Stellar Repair for Exchange for that.
