Hey @Enricoflammini ! 

If you simply want the rule to apply on a different inbox within the same Workspace, you can just edit the “Inbox is….” condition on the rule. 

If you want to transfer a rule from one workspace to another, I’m afraid that this isn’t possible and would be a feature request. You can submit requests here: https://community.front.com/ideas 

You can also reach out to our Support team to request of an export of your rules, or to get more specific help with your workflows.
