I have the same Problem as User "lanit" with the /import/users website in Cloudpanel.

I'm using CloudPanel actual in a lab environment to test and evaluate the product. Everything works fine. Now I would like to migrate Users from a Exchange 2010 /Hosting environment with a cross-forest move. I want to suggest Cloudpanel as our new PanelSolution, but I need a solution for this Problem first 🙂

Best regards

Can you tell me if you have created any mailbox plans AND archive plans? I know you may not have archiving enabled but can you enable it and create a bogus plan and then see if you can access this page?
