Your problem isn't technical, it's financial. Moving away from Windows and Office means converting all the organisation's documents to another format, re-training users in the new OS and productivity suite, re-writing VBA scripts (which often doesn't work well). Then you'd have to de-couple the entire organisation from Active Directory. And refactor (at best) or re-write (at worst) all custom in-house apps that rely on either Windows or Active Directory. It's just too expensive.
