Diagnostics

Twelve ways email data goes missing

Most cases we see are one of these. Each has a different recovery path, which is why we diagnose before quoting.

01 / MECHANICAL

Hard drive head crash

Clicking, grinding or a drive that never spins up. Platters are read in the clean room, never on your machine.

02 / MALWARE

Virus or ransomware

Mail stores encrypted or mangled by malware. We work on a forensic image, not the original.

03 / MEDIA

Bad sectors

Outlook freezes or throws read errors because the sectors holding the PST are degrading.

04 / LOGICAL

Header corruption

DBX, NSF, EDB, OST and PST headers get damaged and the file becomes unmountable.

05 / HUMAN

Deleted Items emptied

Purged mail is usually still on disk until it's overwritten. Stop using the machine now.

06 / POWER

Improper shutdown

An abrupt power cut mid-write leaves the store in a dirty, inconsistent state.

07 / EXCHANGE

Errors 505 & 528

Classic MS Exchange failures where the database won't mount or logs don't replay.

08 / ELECTRICAL

Power surge damage

Fried PCB or NAND controller. The board is repaired or donor-swapped before imaging.

09 / LIMITS

PST size ceiling hit

Legacy 2 GB PST limits corrupt the internal tables and take the mailbox down with them.

10 / SERVER

Server won't start

Mail server fails to boot after a RAID rebuild, patch or controller failure.

11 / SOFTWARE

Failed repair attempts

DIY tools like scanpst run in place and often make the damage permanent. We image first.

12 / MIGRATION

Broken migration

Half-finished Exchange or Google Workspace migration leaves mailboxes split or empty.

Our pricing rule

No data, no charge.

Evaluation and quotation are free. You pay only after we show you a verified list of recovered mail, and only if you approve it. Nothing recovered means nothing invoiced.

The chain of custody

Six steps from crashed to delivered

Every case follows the same audited path. You get a case ID at step one and can ask for status at any point.

01

Free phone consultation

An engineer, not a call centre, works out what failed and whether the media should be powered on again at all.

02

Free media pickup

We collect the drive, server or laptop from your location, logged and sealed, or you drop it at a branch.

03

Media analysis

A full diagnostic report: the fault, the recoverable scope, the turnaround time and a fixed price.

04

Recovery in clean room

Sector-level imaging in a Class 100 environment, then mailbox reconstruction from the image. The original is never written to.

05

You verify the data

Online or on-site, you check the recovered mailboxes, folders, contacts, calendars and attachments before paying.

06

Delivery & wipe

Data is delivered on fresh encrypted media. Our working copies are sanitised to standard and the NDA stands permanently.

Recoverable scope

What actually comes back

Email recovery is not just message bodies. A proper rebuild restores the whole mailbox structure so it mounts cleanly in your client again.

  • Deleted and purged emails including items removed from Deleted Items
  • Full folder hierarchy so the mailbox reopens with its original structure
  • Contacts, calendars, tasks and notes from Outlook and mail servers
  • Attachments extracted and re-linked to their parent messages
  • OST to PST conversion for orphaned offline stores with no server left
  • Multi-user Exchange stores split back out into per-mailbox PSTs
Before you call

Do these three things first

The first hour decides how much is recoverable.

1. Stop using the device
Every write can overwrite the mail you want back.
2. Don't run repair tools
scanpst, chkdsk and format-and-retry make cases unrecoverable.
3. Don't reinstall the client
A fresh profile can resync an empty mailbox over the local store.

Questions we get daily

Straight answers

What should I do immediately after losing email data?

Stop using the affected device or email account so nothing overwrites the lost data, and start the recovery process as soon as possible. Continued use, resyncing the account or running repair utilities is the single most common reason a recoverable case turns unrecoverable.

What types of email data can be recovered?

Deleted emails, contacts, calendars, tasks, attachments and entire mailbox folder structures, from Outlook PST and OST files, Exchange EDB stores, Lotus Notes NSF files, Outlook Express DBX files and server-side mailboxes.

Can deleted emails really be recovered?

Usually, yes. Deleted mail first sits in the Trash or Deleted Items folder. Even after that folder is emptied, the data typically remains on disk until new writes overwrite it, which is where specialised recovery comes in.

What are the signs that email data may be unrecoverable?

The data has already been overwritten, there is no backup of any kind, and standard recovery methods have already failed or were run repeatedly against the original media. Even then, a free diagnosis is worth doing before writing the case off.

What issues are specific to PST files?

Corruption stops the mailbox from opening at all. Older PST formats also carry a 2 GB size ceiling, and hitting it corrupts the file's internal tables, which shows up as Outlook crashing or a server refusing to serve the mailbox.

Is my data confidential during recovery?

Yes. Every case runs under NDA, media is handled in a controlled lab with logged chain of custody, and our working copies are sanitised after delivery. Email data is usually the most sensitive data a business holds and we treat it that way.

How long does an email recovery case take?

Logical cases such as a corrupt PST are often done in one to three working days. Physical failures, RAID sets and multi-drive Exchange servers typically take longer, and one recent multi-drive server case was returned inside ten days. You get an estimated turnaround with the quote.

What does it cost?

Diagnosis, pickup and verification are free, and the recovery price is quoted before any work starts, so there are no surprises. If we recover nothing, you pay nothing.

Very impressed. You guys recovered all the data from my daughter's laptop drive when two other places had given up on it.

Corrupt Outlook file with years of mail in it. Got the mailbox back with folders intact, which was the part I was most worried about.
