Remove Public Folders

Question

I have two mailbox sever in our environment, a virtual EX2010 and physical EX2010. We had migrated from EX2003 to Virtual EX2010 including
Public folders. All the clients are using Outlook 2010 so we don’t need the public folders. All the mailbox have been moved to physical EX2010.
When I try to delete the system and default public folders, I get below error msg. I want to delete all the public and system folders and uninstall
the exchange server roll from the Virtual EX2010. How do I do that?
Action 'Remove' could not be performed on object 'EX:/o=XYZ Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)'.
EX:/o=XYZ Organization/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)

Hi,
I have read the article and i am removing the last  public
folder database from a Mailbox server. According to the article it says “you must first move the data within the public folder database to a public folder
database on another server and then remove the public folder database.”
I don't won’t to the public folder on a mailbox server so can i skip
this step?
I have already removed the data from the folders but when i try to remove the data from
the folder i get below error msg.
error: Cannot delete the object '\NON_IPM_SUBTREE\SCHEDULE+ FREE BUSY\EX:/o=XYZ Organization/ou=Exchange Administrative Group
(FYDIBOHF23SPDLT)'. Please make sure that you specified the correct identity and that you have the correct permissions to delete it.
I have never done this before that’s why need help.
Thank you
for your patience while i hustle to get this work done
Much appreciated
