It is difficult to delete an old public folder from EMC. How to do it: use the ADSIEDIT to clear the old ones.
Right-click on the folder you want to delete from CN=Exchange Administrative Group, CN=Databases, and click delete. The go to Active directory Sites and Services and initiate the replication across the domain.
Go to EMC and refresh.
Thats it.
