MS Exchange Server, the core of email communication system in modern organizations, has a very complex architecture that is based on standard database technology. The key components of the MS Exchange Server are: Information Store and Database Engine. Even those who are not much familiar with the architecture of the Exchange Server might have seen the message Exchange unable to Mount database ‘……’ The message says that the database is not mounted on the Exchange Server. It is very usual to find that the database is not mounted on the Exchange Server. However, how can you mount the database on the Exchange Server?
You can use Exchange Management Console (EMC) to mount database on the Exchange Server (with proper permissions assigned). Follow the steps:
- Open Exchange Management Console and go to Organization Configuration > Mailbox, in the console tree.
- Select the database server on the result pane.
- In the work pane, select the database that is to be mounted.
- In the action pane, click Mount Database.
- Go to the Status column and confirm that the status now is Mounted and not Dismounted.
You can start working on the database after successfully mounting it on the Exchange Server. However, while trying to mount the database on the Exchange Server, you may receive a message of the type ‘unable to mount the database that you specified’.
This error usually happens due to deleted or missing log files in the Exchange Server. You need to perform the following actions to solve this issue.
Verify the Database File Name (For Exchange Server 2010)
- Open Exchange Management Console and go to Organization Configuration > Mailbox in the console tree.
- Go to Database Management tab, right-click on the mailbox database, and click Properties.
- Confirm that the name of the mailbox is in the format 'Mailbox Database XXXXXXXXXXX' where the last part is a number (the name should not include the server name).
Check the State of the Database
- Run the command prompt and type eseutil /mh 'name of the database.'
- When the result appears, check the field State.
- If the state is Clean Shutdown, you can try to mount the database once again.
- If the state is Dirty Shutdown, the database needs repair.
You can use the Eseutil tool for the database repair also. However, by using software tools like Kernel for Exchange Server, you can perform the Exchange Database Recovery instantly without going through any technical complexities.
