Exchange Database EDB file is one of the most important information stores of Exchange Server. Hence any corruption to it can mean that all the information stored within the database can become compromised. The EDB file stores all the data in your Exchange mailbox such as mails, contacts, journals, tasks, calendars etc. One thing to note is that the contents of a dismounted EDB file cannot be directly accessed.
Below are some of the common EDB file corruption problems that Exchange Admins are often faced with:
Dirty Shutdown Error: Dirty shutdown error happens when the Exchange server system was not properly shutdown for one reason or the other. This results in the Exchange database being in dirty shutdown state. Once in such a state, the data within the Exchange database EDB file becomes inaccessible without recovery.
Error 1018: The 1018 error or ‘JET_errReadVerifyFailure’ occurs as a result of page-level corruption and hence is harder to fix using native utilities. Any inconsistencies in the file system or checksum mismatch in the header when writing to disk can trigger this error.
Error 1216: The 1216 error or “JET_errAttachedDatabaseMismatch” occurs when the required header information is missing from the log files. This can happen due to a variety of reasons including sudden Exchange crash.
Error 474: The Event ID 474 error occurs mostly when page verification fails. This can at times also happen due to hardware issues or when a page file being called upon is corrupted.
Error 1009: The Event ID 1009 from MSExchangeMailSubmission often occurs as a result of transport rule configuration problem, resource issues such as low disk space etc. It is recommended that you check the trace logs and performance monitor to identify the root cause. Sometimes restarting the service by rebooting the server can fix the issue.
Solution to these Exchange Errors
The main problem with most of the errors listed above is that they make the Exchange database EDB file unmountable and the data within inaccessible. Now that we have seen the most common errors, it is time we take a look at how to fix these issues so that all the valuable information within Exchange database can be recovered.
The native utilities such as ESEUTIL from Microsoft can help perform soft or hard recovery on the Exchange database files. It is also useful for performing consistency checks on database and to understand what state the database is in. However, they do not form an ideal solution for the errors listed above due to a variety of reasons:
- May fail to recover databases with page level corruption
- Time consuming process with no guaranteed results
- Needs some degree of technical expertise
- No GUI, entirely PowerShell command based
- Rather resource intensive as it needs at least 20% of database size as free space
