Question : Can't Mount or Delete Public Folders Exchange 2010

I'm trying to replicate my public folders from our 2003 server to 2010. When I initiially installed the Mailbox Role, the installation didn't complete and i've been left with clearining out some entries in ADSI Edit. Nothing too spectacular and mostly from advice i've read on these boards.

I managed to create a new set of public folders but they won't mount. When i try to mount them I get this message

--------------------------------------------------------
Microsoft Exchange Error
--------------------------------------------------------
Failed to mount database 'Public Folders 2010'.

When i try to delete them I get this message

--------------------------------------------------------

The public folder database 'Public Folders 2010' cannot be deleted.

What i'm trying to do is to get rid of any 2010 public folders I have and then replicate the 2003 ones we have over to a 2010 database

Thanks

Sounds like you may have deleted something from ADSI Edit that shouldn't have been deleted.

My recommendation would be to run:

setup.com /PS

from the Exchange 2010 DVD
