The MCTS: Microsoft Exchange Server 2010 certification validates your skills in supporting the maintenance and administration of the Exchange servers in an enterprise environment. Learn everything you need to know with this course.
Microsoft Outlook is configured with MS Exchange, and Exchange server saves user mailboxes into Exchange Database (EDB) files. If there is anything erroneous with Exchange Database, it causes a significant effect on email communication till the user remounts the database. Further, database crash directly affects Outlook users due to which they are unable to access their emails or work on their contacts, calendars, emails, and more. Under such circumstances, restore your database with the help of updated backup, but if the backup is not updated, then go for Exchange database recovery either through the manual method or professional software.
When an Exchange database crashes, the user tries to recover the crashed database by moving the ‘log files’ and ‘chk files’ to mount the database and the process was successful, except that a few mailbox users are unable to send or receive emails and the following message is displayed:
1. Restore from backup
The most straightforward solution to overcome this situation is to restore from exchange backup. Exchange users are aware of the fact that they may have to face the problem of Exchange Database crash. Hence they always configure a backup of their database. Use this backup to restore the Exchange database.
If the backup meets all the three conditions, then restore Exchange database from available backup, else use the next best option for repair.
2, Mount Exchange Database
If few of the mailboxes are unable to send and receive emails even after repairing the crashed database, then there are chances of corruption in the underlying database structure. Users have an option to overcome this issue by creating a new database – DB02, and moving all mailboxes from the old database (DB01) to the new database (DB02). Creating a new database ensures that:
Run the following command after creating the new database:
Get-Mailbox -Database DB01 | New-MoveRequest -TargetDatabase DB02 -BatchName "DB01toDB02"
This process transfers all available data within the damaged databases to the new EDB. However, there are chances of data loss. If the mailbox contains important organizationaldata, then the loss may affect business operations. A better solution is to use Stellar Phoenix Mailbox Exchange Recovery to repair the corrupt mailbox and recover all mailbox components without data loss.
3. Recover by creating two EDB Files
Perform the following steps, in case the repair and recover Exchange database process, as described earlier, does not yield desired results. Creating two EDB files separates the corrupt mailboxes from the healthy ones as these corrupt mailboxes are available in a different EDB file. The recovery steps are:
Since the previous information is not available, then mailbox user may end-up losing some critical data and recovery of this data is also not possible due to newly created Exchange database and absence of backup.
4. Repair using Eseutil
The drawbacks of restoring with Exchange PowerShell Management method are
