While doing some housekeeping on an Exchange 2010 server, I needed to delete a mailbox database but couldn’t getting the error shown below:<\/p>\n\n\n\n
PROBLEM:<\/strong><\/p>\n\n\n\n The mailbox database ‘Mailbox Database 2 G-L’ cannot be deleted.<\/p>\n\n\n\n Mailbox Database 2 G-L<\/p>\n\n\n\n Failed<\/p>\n\n\n\n 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>.<\/p>\n\n\n\n RESOLUTION:<\/strong><\/p>\n\n\n\n You’ll find there is some mailbox(es) still on the database, but they may not be visible via the GUI. A possible is a person has a mailbox created, but they have yet to login or recieve a mail, in which case a mailbox is not created yet but is still homed there, the other is an arbitration mailbox that needs to be moved before the database can go.<\/p>\n\n\n\n To fix follow the procedure below:<\/p>\n\n\n\n Name Alias ServerName ProhibitSendQuota<\/p>\n\n\n\n —- —– ———- —————–<\/p>\n\n\n\n SystemMailbox{1f05a927… SystemMailbox{1f0… exch-mbx2 unlimited<\/p>\n\n\n\n SystemMailbox{e0dc1c29… SystemMailbox{e0d… exch-mbx2 unlimited<\/p>\n\n\n\n Here there are two arbitration mailboxes that need to be moved!<\/p>\n\n\n\n > get-mailbox -Database “Mailbox Database 2 G-L” -Arbitration | New-MoveRequest -TargetDatabase “MBX2_DB1”<\/p>\n\n\n\n DisplayName Status TotalMailboxSize TotalArchiveSize PercentComplete<\/p>\n\n\n\n ———– —— —————- —————- —————<\/p>\n\n\n\n Microsoft Exchange App… Queued 161.1 KB (164,933 bytes) 0<\/p>\n\n\n\n Microsoft Exchange Queued 22.7 MB (23,803,480 by… 0<\/p>\n\n\n\n > Get-MoveRequest<\/p>\n\n\n\n DisplayName Status TargetDatabase<\/p>\n\n\n\n ———– —— ————–<\/p>\n\n\n\n Microsoft Exchange Approval Assistant CompletionInProgress MBX2_DB1<\/p>\n\n\n\n Microsoft Exchange CompletionInProgress MBX2_DB1<\/p>\n\n\n\n Wait for them to complete then re-run the first command to check for any hidden mailboxes again.<\/p>\n\n\n\n Nothing shown, we should be good to delete that mailbox store now!<\/p>\n","protected":false},"excerpt":{"rendered":" While doing some housekeeping on an Exchange 2010 server, I needed to delete a mailbox database but couldn’t getting the error shown below: PROBLEM: The mailbox database ‘Mailbox Database 2 G-L’ cannot be deleted.
