SYMPTOMS

A database cannot be mounted after you create a new mailbox database on a computer that is running Microsoft Exchange Server 2007. If you troubleshoot the issue, you may notice that a database file is created successfully at the specified location. However, the following error message is generated in the Exchange log file:

Failed to mount database <DatabaseName>. Error: Exchange is unable to mount the database that you specified. Specified database: <Exchange1\Exchange1-SG2\DB-3>; Error code: MapiExceptionNoAccess: Unable to mount database, (hr=0x80070005, ec=-2147024891)

CAUSE

This issue occurs because the Exchange Administrative group is missing write permission for the msExchDatabaseCreated object.

Back to the top

RESOLUTION

Write permission for the msExchDatabaseCreated object is inherited from the Exchange Organization container. To resolve this issue, run the following command to add the required permission at the organization level. To do this, follow these steps:

Log on to Exchange server or the administrator workstation by using an account that has administrative credentials.
Open Exchange Management Shell.
In Exchange Management Shell, type CD \, and then press ENTER.

Note There is a space between the CD command and the backslash character (\).
Run the following command.
Add-ADPermission -id "CN=<FourthCoffee>,CN=Microsoft Exchange,CN=Services,CN=Configuration,DC=<fourthcoffee>,DC=com" -User "Exchange Servers" -AccessRights WriteProperty -Properties "ms-Exch-Database-Created"
Note Change the distinguished name to match the distinguished name of your Exchange organization. You can obtain the distinguished name of your organization by using the ADSIEDIT or LDP tools.
