We are finalizing the exchange migration from 2010 to 2016.
After following the steps in https://learn.microsoft.com/en-us/exchange/collaboration/public-folders/batch-migration-from-previou... we started deleting the proxy mailbox on exchange 2010 and its mailbox DB to be able to remove the exchange 2010 server.
However checking the organization we found that the RemotePublicFolderMailboxes : still points to the "deleted" object
