We are running Exchange 2013 migrating from Exchange 2007. The last thing that I need to do to complete the migration is to migrate the public folders. There seems to be an issue, when I run a public folder command (Get-PublicFolder) I get the following error. I found this article but it really doesn't help. In order to migrate these folders I need run the commands. Any assistance appreciated.

Where do you run this command, Exchange 2013?  I believe that's normal (but I don't have a mixed environment to check it) because Exchange 2013 doesn't have any public folders yet.  You'll continue to manage public folders using Exchange 2007 tools until you migrate them over to Exch
