It is generous of you to take the time to offer a suggestion on a
version
that you haven't used.
When asking for help, please mention which version. The versions
exist because each contains added functionality or change in behavior.
What works for fixing a problem in one version may not work or even be
applicable to a different version.
So did creating a new identity give you the standard set of folders?
If so, try using the old .pst file with the new identity. Unless I
have missed the posts, whether old or beta version, I haven't seen
anyone suggesting how to repair corrupted identities. I have,
however, seen suggestions to create new identities and use your old
data there.
