Dirty Shutdown is a database state that occurs because of missing, deleted, or corrupt transaction log files. A database in Dirty Shutdown state prevents the Microsoft Exchange Server from mounting. This can cause disruptions to email services. You can quickly resolve this complex problem by repairing the EDB file using this advanced Exchange recovery tool.
The Exchange server database may not open and display an error message stating 'Failed Error: Couldn't mount the specified database.' This error message indicates that the specified database cannot be mounted. To solve the problem, you have two options. The first option is to restore the Exchange database from a recent backup. The second option is to use a reliable Exchange EDB recovery software like Stellar Repair for Exchange.
When Exchange server crashes, an administrator can use setup /m: RecoverServer switch command to rebuild a new Exchange server. However, database recovery is a more challenging task, based on the nature of the failure. Stellar Toolkit for Exchange helps you recover mailboxes from .edb file of crashed Exchange server, especially when ESEUtil fails, logs are missing or deleted, and backup is not available.See ESEUtil & Stellar Repair for Exchange Comparison.
Software Important Capabilities
Exchange Server Recovery software uses robust scanning algorithms to retrieve mailbox items from corrupt or dismounted EDB files. The "Select Scan Mode" feature provides two options – Quick Scan and Extensive Scan to perform effortless EDB recovery. The Quick Scan option repairs most of the database corruption and dismounting issues. However, Extensive Scan provides an advanced scanning option that provides better results and takes more time. Stellar Repair for Exchange recovers Exchange mailboxes from different EDB files, maintaining the folder structure.
Hackers can take over Exchange Servers by using vulnerabilities like ProxyLogon, ProxyShell, and ProxyOracle to install harmful programs like ransomware. To protect the Exchange Servers against such attacks, install Microsoft's Exchange latest updates and security patches. If your Exchange Server is hacked, you can use Stellar Repair for Exchange to recover mailboxes from damaged databases. You can then transfer the recovered mailboxes to a new Exchange server or Office 365 account.
Stellar Exchange mailbox repair software can export the recovered mailboxes directly to Office 365 (Microsoft 365). To export to Microsoft 365, you just need to connect to the Target Server using either Auto Registration or Manual Registration. Use Auto Registration to automatically connect to Microsoft 365 by using the Microsoft Azure credentials. For Manual Registration, you need to manually enter the details, such as Email Address, Application (Client) ID, Directory (Tenant) ID and Client Secret Value. To get these details, you can create an application in Microsoft Entra ID. After this, you have to upload the CSV file containing a list of mailboxes. The tool will automatically map the mailboxes, using the mailbox IDs, from the source (EDB file) to the mailboxes on Microsoft 365. In addition, it allows to perform incremental data migration to Microsoft 365.
Stellar Exchange mailbox recovery tool can export the recovered mailboxes directly to a live Exchange Server, thus minimizing server downtime. To Export to Live Exchange, you just need to enter the admin login credentials and then upload the CSV file containing list of mailboxes of the destination server. The software opens a Map Mailboxes window where it automatically maps mailboxes to the destination Exchange Server mailboxes using mailbox IDs. It also offers options to manually map the mailboxes, un-map the mailboxes, or change the priority order. If any mailbox is not mapped with the destination server mailbox, the software also shows a prompt to go back and map the mailboxes again or skip the mapping. Moreover, it allows to perform incremental data migration to live Exchange Server.
