Inbox and Legacy lists


We recently turned on INBOX, and now when people go to Communicate -> Compose Email, the legacy mail lists are available as an option, but the INBOXes are not listed. This has created confusion, and as I have moved legacy lists to the INBOX format, it seems that people can’t find the lists anymore.

Is the design intention that everyone has access to the INBOX interface, and only members of the boxes can access their boxes? Should people be composing emails to lists from the INBOX interface?

Or should they continue to use the Compose Email function and I need to do something to switch out the legacy lists for the INBOX lists?
