The error message itself has the solution. Go ahead and delete the Mailboxes (Under Mailbox Database 1229298607) you must have created. Once all the mailboxes has been deleted, you will be able to uninstall Exchange 2010.

I had this issue on my lab the other week, first remove any mailboxes, if you still have an issue (Which I did) you can forcibly remove exchange 2010 by doing the following

(If this is your only exchange you want removing)

Open adsiedit.msc, open configuration > Services and delete CN=Microsoft Exchange (this removes the entire org)
If you jsut want 1 server gone go down 1 more lever to CN=Servers and remove your server.

Then Use Registry Editor to remove the following Exchange registry keys form the server itself


Then delete the exchange install files.

I reinstalled exchange after doing the above btw then broke it and removed it again and it still runs ok after reinstalling.

Get-Mailbox -Database 'Mailbox Database 1229298607' -Arbitration | disable-mailbox -arbitraion -DisableLastArbitrationMailboxAllowed :$true

you ran the get-mailbox from the exchange management shell ?
DoganaAuthor Commented:
no. how?
AkhaterSolutions ArchitectCommented:
search for something called "Exchange Management Shell" run it as administrator

and run

Get-Mailbox -Database 'Mailbox Database 1229298607' | disable-mailbox

Get-Mailbox -Database 'Mailbox Database 1229298607' -Arbitration | disable-mailbox -arbitraion -DisableLastArbitrationMailboxAllowed :$true
