When you insert a new record in Exchange database table, Exchange inserts the corresponding index entry into index. For any reason, if the data page is flushed, but its index remains intact, database inconsistency might arise. This state of database is known as ‘lost flush’. Since the database comes to a dirty state, you should immediately apply the appropriate eseutil commands to repair it. If this doesn’t solve the issue, you need to restore the database from backup or use effective Exchange Server Recovery applications.
For instance, you might observe that Microsoft Exchange Information Store services stops responding at repeated intervals of time in a day. When you view the application event log, it shows event ID 467 associated with a 1025 warning as below:
Warning 1025: An error occurred on database -First Storage Group\Public Folder Store (server_name)-. Function name or description of problem: SLINK :: EcUpdate Error: 0xfffffa7a-
You come across a similar warning each time when event 467 is logged in MSExchangeIS public or private store.
Event 467 typically indicates secondary index inconsistency with the associated table. The database page is corrupted and is causing JET engine to hang.
To solve the issue, you need to first locate the corrupted database, which is specified in the Description section of event occurred. If you cannot view this information, you should first install the supported hotfix to include it. After the affected database is traced, follow these steps:
1. Start Exchange System Manager and dismount the database causing the issue.
2. Run eseutil /g command to confirm for database inconsistency
3. Run eseutil /d command to defragment and fix the corruption
4. Mount the database store
If the issue persists, delete the database provided you have a valid backup. In case of any issues with backup, you are suggested to use third-party Exchange Server Recovery solutions. These are powerful tools built to run high-end scanning algorithms for repairing the corrupted Exchange database. Microsoft Exchange Recovery utilities provide interactive design and thus, prove easy to implement solutions.
