Mailbox Recovery
We recover your data professionally and are very experienced in the recovery of mailboxes.

Mailbox Recovery

Attingo reconstructs defective databases from e-mail servers, defective mailboxes or deleted mail. Profound knowledge on the structure of e-mail database servers and mailboxes is the necessary condition for helping with data loss.

  • Data recovery and conversion from Outlook, Exchange and mbox mailboxes
  • Data recovery of corrupt mailboxes
  • Data recovery of deleted mailboxes

Outlook and Exchange recovery

Attingo has reverse engineered the proprietary storage formats of .pst mailboxes, .ost cache files and .edb databases, in order to make data rescue or conversion possible.

Mbox mailbox recovery

Attingo also reconstructs data from UNIX-based .mbox mailboxes (or .mbx files). Proprietary implementations of these are currenty used by Mozilla Thunderbird, Apple Mail and Eudora. When it comes to Thunderbild, structural errors in the .msf index file may occur.

Causes for data loss from e-mail archives

Physical storage falls out

Storage failure or damage may lead to losing the saved e-mail database or mailboxes. The storage can be a RAID system, a single hard drive or a SSD.

Errors in the file system

Errors in the file system may induce data loss from e-mail databases and mailboxes. A sudden operating system crash or a blackout result in transactions not being written correctly and provoking data loss. A common symptom is the 0-byte-problem: the database only has a file size of 0 bytes. To prevent the damage from getting worse it is very important to shut the server down immediately and not apply power anymore.

Deleted e-mail, mailboxes, agendas, notes or contacts

It often happens that mailboxes, notes, agendas or contacts ar deleted by accident, for example during a migration.

Corruptive mailox, e-mail database, agenda, notes or contacts

Data reconstruction is also possible from corruptive e-mail databases, for example a defective Microsoft Outlook .pst or .ost file, Lotus Notes .nsf archives or Exchange .edb files.

It its often necessary to convert e-mail servers, e.g. extracting the different inboxes from Exchange databases as Outlook .pst files.

Ich kenne Attingo schon seit einigen Jahren und hatte das damals von einem A1 Telekom Servicetechniker empfohlen bekommen. Danach habe ich mir das Webportal Ihres Unternehmens aufmerksam durchgesehen. Es brauchte nicht viele Worte und ich erkannte: "...besser geht es nicht. Hier bist du bei echten Profis!".

Macht bitte weiter so - und informiert auch weiter, wie wichtig und vernünftig es ist, keine "Datenrettungstricks" oder Tipps aus Halbwissen auszuprobieren. Das klappt oft deshalb schon nicht, weil das Knowhow und die professionelle Ausstattung eben Experten braucht...

Rasch und professionell
