Core features

Email Restore Tool Features in Four Screens

Four screens of the restore tool, in the order a restore runs.

Main window with backup files loaded

Load the file

Load PST, MBOX or EML Backup Files

Add one backup file or a full folder of them. The email recovery software recognises the format from the file itself, so a Thunderbird MBOX and an Outlook PST load the same way.

  • One file, a folder or several files at once
  • Format detected automatically, no setup
  • No size cap on the file or the mailbox
  • Backup opens read-only
Folder tree with selection checkboxes

Folder selection

Select Lost Folders to Restore

The backup appears in a checkbox tree. Restoring one lost folder works exactly like restoring a full archive, useful when the live mailbox already holds most of the mail.

  • Tick or untick any folder in the backup
  • Totals per folder before the restore begins
  • Narrow by dates, keywords, sender or subject line
  • Leave the rest of the backup untouched
Message preview with hex and raw views

Message preview

Preview Emails Before the Restore

Check any message in a preview pane before it goes back online. Alongside it, four analysis views serve IT admins and forensic teams.

  • Content holds the message beside its subject and sender
  • Message header tracks authentication results hop by hop
  • Properties gathers size, priority and file details
  • Hex and raw message open the source byte by byte
Choosing where the mail is restored

Destination

Restore Emails to Gmail, Microsoft 365 or IMAP

Sign in to the account that should receive the mail. It need not be the original account, so mail from a closed work address can land in a personal one.

  • Restores to Gmail, Microsoft 365, Outlook.com or Yahoo
  • Restores to Thunderbird or any IMAP host
  • Folders, attachments, dates and read/unread status preserved
  • Contacts, calendars and tasks land alongside the mail
  • A different account works too, see the email migration tool for live moves

Before restoring

Email Recovery Software Needs a Backup File

Restore software in the plain sense: it opens an existing backup file and restores it into a mailbox. Two jobs it does not do are listed below, so nobody downloads it for the wrong purpose.

Yes

Restore from a backup

A PST, MBOX, EML or Takeout file sits on a disk. The software opens it and restores the mail into a live account, folders and all.

No

Undelete with no backup

If mail was deleted and no backup exists, there is nothing here to restore. Check the provider's own trash or retention window first.

No

Repair a corrupt file

A damaged PST needs a repair tool instead of a restore tool. The guide repair PST file without ScanPST tool covers that.

No backup yet? The email backup software creates one from a live account. The restore tool brings it back later.

To open a file without restoring anything, use the free email viewer software. To create the backup file first, use the Gmail backup tool, Outlook.com backup tool, Hotmail backup tool, Office 365 backup tool, Yahoo backup tool, iCloud backup tool, Webmail backup tool or Google Workspace backup tool.

Common questions

Email Recovery Software Questions

What the restore tool opens, where it restores mail and where it stops.

Can email recovery software recover emails with no backup?

No. This tool restores a backup file into a mailbox. With no file there is nothing to restore. Check the trash folder in your webmail first, then any retention or recovery window your provider offers, since those work on the server side out of reach of any desktop tool.

Will it fix a damaged PST file?

No. A damaged file needs a repair tool that rebuilds the structure. This restore tool expects a healthy file and restores what is inside it. The guide repair PST file without ScanPST tool walks through repair.

Does the restore modify my backup file?

No. The file opens read-only. Nothing is added to it, moved inside it or deleted from it, so you can restore the same backup again later or keep it as the archive copy.

Can I restore to a different account than the backup came from?

Yes. You sign in to whichever mailbox should receive the mail. Mail from a closed work address can land in a personal Gmail account. A Thunderbird archive can go into Microsoft 365.

Will it create duplicates in a mailbox that already has some of the mail?

Avoid them by restoring only the folders you lost instead of the full archive. The folder tree carries a checkbox on every branch. Date and keyword filters narrow it further before anything is restored.

Does it restore contacts and calendars too?

Yes. Whatever the backup contains goes back: contacts, calendars, tasks and notes reach the destination account with the mail. A lone vCard file restores as contacts.

Which backup formats can the restore tool open?

PST, OST, MBOX, EML, EMLX, MSG, DBX, OFT, OLM, vCard, Maildir, Eudora and Google Takeout. The type is detected automatically, so there is nothing to set by hand.

Is my backup uploaded to Corbett?

No. The software runs on your PC, opens the file from your disk and connects straight to your mail provider. Corbett stores and relays none of it.

How big a backup file can it restore?

No. A big archive takes longer because the destination provider limits upload speed. If the connection drops, the restore carries on from the last message saved.

Does the restore tool support macOS?

No. It is built for Windows only. Any desktop edition from Windows 7 runs it, as do Windows Server versions released since 2008.

Will Gmail, Yahoo or iCloud ask for an app password during a restore?

Yes, where two-step verification is on, which is now standard on all three. Create an app password in the account's security settings and enter it instead of the normal password.

How much can the free restore demo do?

The demo loads any supported backup, shows the folder tree and unlocks every preview and filter. Restores cap out at 10 emails per folder, enough to confirm the backup works.

Must Outlook or Thunderbird be installed?

No. It opens PST, MBOX and the rest on its own, so a PC with no mail client can still restore a backup.

Restored an archive team wide

I had to restore a large amount of data from old backup data. The software allows me to recover multiple emails at once to desirable email platforms. It saved our team a lot of time and effort.

Sarah Collins

Trial let me test it before paying

I used this tool to recover permanently deleted emails from backup files. The software interface is simple and easy to use. I highly recommend this tool as it also offers a trial version to test software before purchase.

Daniel Brooks

Search found the exact messages

The advanced search feature helped me recover specific emails. I restored emails to Thunderbird without any errors. It is a standalone application that does not need any email client or extra setup.
