Migrate from Exchange 2007 to 2010 – Remove public folder error (Internet Newsgroup)

When trying to Remove the publicfolder replicas from a Exchange 2007 server i could not remove one public folder called Internet Newsgroup.

As far as i understand this is a heritage from legacy versions of Exchange. This was intended to be used for a local NNTP source, where an org could have a local copy of some select newsgroups for their users to view.

To delete this folder and to be able to uninstall Exchange 2007 i had to use Adsiedit and delete the public folder record.

 

  1. Open Adsiedit.msc from run command
  2. Connect to your server (right-click on ADSI Edit, then Connect). Select Configuration for the well known Naming Context
  3. Expand to CN=Services,CN=Microsoft Exchange,CN=your organization name,CN=Administrative Groups,CN=Exchange Administrative Group,CN=Servers/CN=Your MailBox Server. Expand it and then locate Information Store.
  4. Locate particular storage group where is Public Folder Store. On the right pane, delete the public folder record under the storage group.

Make sure that you have moved all your replicas to the new Exchange server before you do this !
