Hi Folks,

in my new company with Exchange Server 2010, I just found out that there is a random Database that seems to be unused with the name "Mailbox Database 1678302020 " in the C:\ drive of the mailbox server.

So how can I delete this mailbox database safely without causing any problem later on down the  track?
From the Exchange Management console, the content of this database is 0 or no mailbox associated with it.

no DAG is configured in the mailbox server.

You basically just have to remove all the mailboxes from the database (if there are any) then you should be able to safely dismount, then remove the database (both commands are accessible via the right click menu).

Exchange will not let you remove the database if there is anything using it.
The name of the database suggests this is the default database that is created when Exchange is first installed, which means it will have system mailboxes located in it which will need to be moved to another database.
