I lost the drive for a temporary mailbox database that was created. Now of course this database still shows up in EMC and logs errors in the event viewer. There were no active users on that database but when I try to delete it, I get the following error messages. -------------------------------------------------------- Microsoft Exchange Error -------------------------------------------------------- The mailbox database DB1 cannot be deleted. DB1 Failed Error: This mailbox database contains one or more mailboxes, mailbox plans, archive mailboxes, or arbitration mailboxes. To get a list of all mailboxes in this database, run the command Get-Mailbox -Database <Database ID>. To get a list of all mailbox plans in this database, run the command Get-MailboxPlan. To get a list of archive mailboxes in this database, run the command Get-Mailbox -Database <Database ID> -Archive. To get a list of all arbitration mailboxes in this database, run the command Get-Mailbox -Database <Database ID> -Arbitration. To disable a non-arbitration mailbox so that you can delete the mailbox database, run the command Disable-Mailbox <Mailbox ID>. To disable an archive mailbox so you can delete the mailbox database, run the command Disable-Mailbox <Mailbox ID> -Archive. Arbitration mailboxes should be moved to another server; to do this, run the command New-MoveRequest <parameters>. If this is the last server in the organization, run the command Disable-Mailbox <Mailbox ID> -Arbitration -DisableLastArbitrationMailboxAllowed to disable the arbitration mailbox. Mailbox plans should be moved to another server; to do this, run the command Set-MailboxPlan <MailboxPlan ID> -Database <Database ID>. Going through was is indicated in this message I get the following results Get-Mailbox -Database <Database ID> (no results) Get-MailboxPlan (returns an error message about not being a valid cmdlet) Get-Mailbox -Database <Database ID> -archive (no results) Get-Mailbox -Database <Database ID> -arbitration (I obtain two mailboxes. Of couse I can't move these mailboxes since I don't have access to the database). Any ideas anyone as to how I can get rid of this database? ThanksFrancois S. at FMD

Your only option is to whack it from adsiedit or to recover the DB then delete it. Start run, type Adsiedit.msc Connect to the configuration partition. Expand Configuration-Services-Microsoft Exchange-<Organization Name>-Administrative Groups-Servers-<Messaging Server name>-Information Stores. Delete the appropriate Storage group from here or you can drill down further and delete the appropriate database that is causing the problem.James Chong MCITP | EA | EMA; MCSE | M+, S+ Security+, Project+, ITIL msexchangetips.blogspot.com
