Email Database Recovery

Mail stores are dense, structured files that corrupt in predictable ways. AS recovers mailboxes, folders and messages from Exchange, Outlook and server-side mail stores.

When you need this

  • Exchange database won't mount or fails eseutil checks
  • PST corrupted, oversized or reports as unreadable
  • OST file with unsynced mail after account loss
  • Mail server store deleted or encrypted
  • Mailboxes purged past the retention window

What we do

Exchange EDB recovery

Mailboxes are extracted directly from damaged EDB files without requiring a working Exchange server.

PST/OST recovery

Corrupted PST and OST files are parsed to recover messages, attachments, contacts and calendar items.

Export and validation

Recovered mailboxes are delivered in usable formats (PST, EML, MSG) and spot-checked for integrity.

A database data file as a sequence of fixed-size pages, with a byte-level view of a damaged page header next to an intact oneData file, read page by pageEach page has its own header (page ID, type, checksum/LSN) and contentintact page headerdamaged / encrypted pagesPage header, byte level (illustrative)intact page:4E000800010000003A91damaged page:0000????01000000FFFFPage type and checksum bytes don't match what's expected — a technician confirms this directly in ahex/disk editor before deciding whether the page is recoverable or needs to be skipped.Why this matters for recoveryA few unreadable pages don't make the rest of the file unreadable. Parsing the file directly, page bypage, recovers what's intact even when the database engine itself refuses to open the file at all.

Exchange EDB stores and PST/OST files are dense, structured containers of their own — damage to part of the store doesn't make every mailbox and folder inside it unreadable.

How it works

  1. Step 1

    Consultation and scope

    We establish what failed, what has been tried, and which data matters most. This shapes a targeted plan rather than a generic one.

  2. Step 2

    Secure imaging and diagnosis

    Where possible the source media is imaged before any work, so the original is never altered. Diagnosis then determines the safest recovery method.

  3. Step 3

    Recovery

    Data is extracted from the image or source using methods matched to the failure — logical, structural or hardware-level as required.

  4. Step 4

    Verification

    Recovered data is checked for integrity and completeness, and a file list is shared so you can confirm what matters is there.

  5. Step 5

    Secure delivery

    Verified data is returned through an agreed secure method, with guidance on validation before it goes back into production.

What affects the outcome

We have solved 656+ cases like these. Every case is assessed on its own condition, and we tell you exactly what is recoverable after a free assessment, before you pay anything.

  • Physical condition of the media and the extent of any damage
  • Whether the media has been written to, reformatted or re-initialised since the failure
  • Encryption, corruption or partial overwriting of the data
  • Availability of source data such as images, backups, logs or transaction records
  • Attempts made before assessment (rebuilds, repair tools, repeated reboots)

Frequently asked questions

Can mail be recovered from an orphaned OST file?

Often, yes. Cached content in the OST can be converted to a PST even when the original account no longer exists.

Do you need Exchange running?

No. Recovery works from the database files themselves.
