How to resolve Exchange Private (Priv1.edb) EDB file Error?

Microsoft Exchange Server along with MS Outlook provides a world-class experience of mailing, instant messaging, calendar, notes etc to the users with various exquisite features. Focussing on how Exchange Server keeps its data centralized, it is found that it incorporates Extensible Storage Engine (ESE) facility to keep all the email items along with their log files. Now during Exchange Server installation, two files are created Priv1.edb files and Priv1.stm files. This STM file is generated corresponding to each EDB file.

Priv1.edb file stores all email messages, attachments, headers and non-SMTP email messages whereas on the other hand Priv1.stm file is concerned with MIME data, Internet related graphics, photos, videos etc. Hence we can say that Priv1.edb file is the prime file which stores all your important work so any kind of corruption to it must be necessarily avoided. However, we cannot be sure of everything and must be ready with combat strategies if any kind of mishappening occurs with Priv1.edb file.

Now whenever if there will be any problem in your Private EDB file, it could be sensed with these kinds of various errors:

  • Various Jet Engine Errors like "JET_errRecordNotFound", "JET_errDatabaseCorruptedNoRepair", "JET_errRecordDeleted" etc.
  • Corruption or damage prevailing in the Header information.
  • Duplicate Keys or Identifiers created.
  • Exchange Server Error Code 528.

This damage in EDB files is caused due to these following illustrated reasons:

  • Accidental or improper closing of Exchange Server.
  • Power failure which causes improper shutdown.
  • Virus or malware attack.
  • Hardware or System crash.

When you come across any such corruption or damage in your private EDB files then you can follow these instructions which incorporate the use of ESEUTIL and ISINTEG.

  • It is necessary to first take the backup of the EDB files before performing any action.

These steps will help you in repairing your corrupted EDB files but requires a thorough knowledge of both ESEUTIL and ISINTEG tool along with hands on experience of using Exchange Server. However at times despite of performing these steps you are not guaranteed of errors being resolved. So in order to successfully repair corrupted files, experts recommend third-party Exchange Recovery professional tool which does not require any technical acumen and presents most reliable and trustworthy results.
