we recently migrated from exchange 2007 to 2013.
The only thing left is the public folder - We never used it in Exchange 2013 but want to use it in 2013.
I simply want to delete it on the 2007 and create new mailbox on the 2013 server. When i try to remove the database from the 2007 server it states that the database was created in a future version of exchange.
What is my best route from here.
