I don't see any value there.

If the user is not permitted access to a mailbox, they don't get the
information. There might be value sending the notice to an exception
log, but it does not make much sense to send it to the user's client.
If the user is trying to maliciously access material they should not,
what would be the value in telling them?

The use case that would likely arise for this would be where there are
shared folders (e.g. mailing lists) in some sort of hierarchy.
