i have removed / re-created the arbitration mailboxes as the first default database is dismounted and will not mount anymore. Now i find i have outstanding import request that must be cleared but can't due to the database not being ABLE to be mounted Any idea on hw to remove the import requests so i can trash this database out completely. This is UAT so i am not convered with data loss

Hi, Get the guid of two arbitartion mail boxes and move to different database and try to delete again Get-Mailbox -Database DB01 -Arbitration | ft -wrap -auto Move-Mailbox “SystemMailbox{'guid'}” -Arbitration -TargetDatabase DB02 Move-Mailbox “SystemMailbox{'guid'}” -Arbitration -TargetDatabase DB02 Regards from www.windowsadmin.info

Find out detail steps in below Amit Post. Mount databse again then remove import request and then move arbitrion mailbox into other store and delete it. Also you can delete orbitration mailbox directly. Get-Mailbox -Arbitration -Database "Mailbox Database 29837493" | Remove-Mailbox -Arbitration -RemoveLastArbitrationMailboxAllowed http://muc-ug.org.in/index.php/how-to/exchange-2010/94-default-mailbox-database-a-move-arbitration-mailboxes.html Anil

both this solutions require the database to be mounted...

Hi, First, I would like to confirm the following questions: 1. What does the “outstanding import request” mean? 2. Why the original database cannot be mounted? Is there any error message when trying to mount the database? To troubleshoot the issue, please type Get-Mailbox -database <database ID> cmdlet about the problematic databse and post the result here.
