Exchange 2010. Install Failed, now can't uninstall

I was attempting to transition our Exchange 2003 environment to a new server running Windows Server 2008 R2 x64. I installed Exchange 2010, but the mailbox role failed. I tried three times to get it right without success. (My Exchnage 2003 server is still working perfectly)

I came back to the problem the following day to find that windows had done updates at 3am in the monring and restarted. Half the Exchnage services wouldn't start and it wouldn't let me install the mailbox role. It mentioned that the role was partially installed and that I must remove it first.

It will not uninstall the mailbox role with the following error:

Open Exchange Management console -> Org config -> mailbox -> database management

Find your mailbox database -> right click properties -> client settings

You should see it using the public folder database on exchange 2010, assign the 2003 one to it

Can I do this via powershell? After this corrupt install and with various services not starting, I can't open management console. It won't connect.

I just get the error below/attached when trying to connect via powershell. Powershell works if I stop W3sv but then the command you mention doesn't work.
 $Mailboxes | ForEach { If($_.UmEnabled -Eq $False){$_.Name}}

well it seems your installation is badly messed up

open adsiedit.msc -> connect to the configuration partition

browse to services -> ms exchange -> org name -> administrative groups -> exchange admin group (xxxxX) -> databases


find the public folder database and the mailbox database that were create on exchange 2010 and delete them
