After bringing up a mailbox server, it automatically creates an initial database. I have created other databases that we plan to use, is it safe to delete that initial database? there appears to be nothing in it.

There should be the initial system mailboxes in there. That's why I prefer to rename and move the first database.

By the way, you can now specify the name and paths of the mailbox database and log files in the setup.com command line.

Yes, it is safe to remove the database. Exchange won't let you remove the database if it contains any mailboxes. From memory, the first E2010 database contains arbitration mailboxes.

Alexei, do you mean the first Exchange 2010 database in the org, or the first one on each mailbox server

Also, if the server were to have only database copies, and no active databases, would it still be safe to delete the initially created database? The System Attendant does not have a mailbox in Exchange 2010, is that correct?

As Alexeia says the first DB contains arbitration as well as the system mailboxes.

You can find and move these using Get-Mailbox -Arbitration, then generate Move Requests to move these mailboxes to their new destination. Exchange won't let you delete the DB until you've moved these mailboxes off.

However as Ed says it's easy enough to dismount and move the database path to somewhere more suitable. You can do this all in the EMC.

First Exchange 2010 database in the org.

It's fine to just have passive copies. You don't need to have the initially created database. In fact you don't need any database at all.

Correct - you don't have System Attendant mailboxes in E2010.

Thank you all. Using this article, and your advice, I was able to move those arbitration mailboxes, so I was able to remove those initially created databases on each of our exchange servers.

The only thing to note is that there is also a 4th mailbox, DiscoverySearchMailbox, that needs to be moved from the very first database created, in addition to the 3 pointed out in the above article.
