Whilst I can't help with your technical problem, I can offer the advice
that you should think very carefully about reusing "user B" in the
future and, therefore deleting "user B" rather than just disabling them.

For example, if you reuse the "user B" then there's a chance
that that user will receive mail intended for the old "user B".

Whilst there's probably a technical solution to the question you ask,
the social aspects are much wider and once you start going down that
rabbit hole then you're in for an interesting ride.
