Exchange 2010 default daeftabase? what to do with it? Ref: TFr
Exchange 2007 SP2 and Exchange 2010 SP1 At this customer site we have Ex2007 and Ex2010 coexisting as a transition stage. When I installed the Mailbox Role I noticed there is a database identified as "Mailbox Database 1079519039" . What's the practice regarding that database? To leave it alone or could I remove it? Thanks and please provide Microsoft documentation regarding this default Ex2010 database best practice. John

I'm not aware of any official Microsoft document on the process, but you're not required to keep the default database. You just need to move all mailboxes, including arbitration mailboxes, to a new database before deleting it. Several blogs have covered the process: http://www.howexchangeworks.com/2009/11/error-while-deleting-default-mailbox.html http://smtpport25.wordpress.com/2010/08/21/removing-first-exchange-2010-database/ http://muc-ug.org.in/index.php/how-to/exchange-2010/94-default-mailbox-database-a-move-arbitration-mailboxes.html Mike Pfeiffer | blog: mikepfeiffer.net | twitter: @mike_pfeiffer

This is the default mailbox database that gets created during the install of the mailbox role. If this is the first 2010 mailbox database created, then it also will have some special mailboxes (arbitration) associated with it. There is no "best practice" on whether to remove it or leave it...It is up to you on whether you want to delete it or make it conform to your "standards" of mailbox configuration (db and log locations, etc). I personally like to configure my own databases and delete any default databases that come with the Exchange install (but that is just me). It is perfectly ok to leave it or remove it. This article will show you how to view and move the arbitration mailboxes to another database: http://howdouc.blogspot.com/2010/07/arbitration-mailboxes-and-moderated.html If you decide to keep the first database, this article will explain how to rename and modify the paths: http://www.howexchangeworks.com/2010/06/dealing-with-first-exchange-2010.htmlTim Harrington | MVP: Exchange | MCITP: EMA 2007/2010, MCITP: Server 2008, MCTS: OCS | Blog: http://HowDoUC.blogspot.com | Twitter: @twharrington
