Among the many file formats that are familiar to the Exchange users, the name EDB is the most used one. The EDB, otherwise known as Exchange database can be the only source where users can find the emails, drafts, appointment schedule, journals, to-do list, and calendars created while working within the Exchange-Outlook platform. All these data are available in the EDB mailbox and can be used under a user-account created in Exchange. On the other hand, PST files match the Outlook architecture and provide easy access to data hence the suggestion to extract offline EDB to PST rather than trying the default methods of data recovery and repair in Exchange platform.
Common Reasons for EDB Mailbox Corruption
There are many reasons why the EDB mailbox may be corrupted as shown below:
- Improper system downtime and malfunctioning of the methods of database retrieval.
- Accidental quarantine 0f EDB log files by faulty Anti-Virus programs.
- Non-responsive information store as a result of issues with installed backup software.
- File size issues with the Exchange EDB store (e.g. information store exceeding 16GB).
- Any kind of hardware or software issues that may lead to EDB data corruption.
The above are some of the most common reasons behind EDB file corruption. However, there can be additional reasons which may be broadly categorized as physical and logical reasons.
Error Messages that Say EDB is Corrupted and need to go for Exchange Recovery
Exchange recovery could be a last resort in dealing with EDB file corruption when error messages are shown. Examples of some of the most commonly displayed errors when an EDB file is corrupted prior to restoring the database, performing an Exchange recovery or performing an offline EDB to PST conversion are as follows:
- Exchange error with number strings like 5.7.1, 4.4.7, 550, 12014, 3005, 400 4.4.7.
- #5.5.0 smtp;554 Transaction Failed Spam Message not queued.
- Exchange ActiveSync errors, HTTP_500 and SMTP problem, SSL Event ID errors 3029, 3030 and 3031.
- 0x80830003 synchronization failure…….. and many more.
Now, How to Recover Deleted Exchange Messages!
Exchange recovery process becomes mandatory when there are many error messages and corruption issues. In such cases, the need for data recovery can be satisfied using default Exchange utilities like ESEUTIL /P & ISINTEG etc. However, the default utilities prove to be helpful only in cases of mild corruptions, data damage and data deletion issues. This implies that in cases where there is a need to recover deleted Exchange messages these utilities can fail and will not satisfy user-need as a result.
Alternatively, to get the entire Exchange recovery process done a user can restore or move offline EDB to PST using third-party software such as Exchange Recovery. Irrespective of the corruption issues that may have occured or the threat of data loss third-party tools such as Exchange Recovery can work to move EDB to PST successfully thereby helping to recover deleted Exchange messages. Thus, emails, contacts, calendar, journals or any other data such as EDB, Pub1.edb, Priv1.edb and all custom and default folders in the mailbox can be recovered.
