There are no legitimate VBA options to unprotect a protected document for forms. I agree with kjv, hopefully use this as a corporate lesson. ANY corporate file should require a corporate storage of passwords, separately stored.
While there are "crack" solutions for breaking passwords to access a Word file, this is different from the password for protecting a file for forms. There may indeed be crack solutions out there for this as, essentially. it is the same problem. These solutions basically use a brute force method.
I would agree with your thought of re-creating the file.
