Exchange does it that way :)
We're encountering problems with the migration from Dovecot ->
Exchange, because users can generate huge emails in Sent and Drafts
(which are never sent out, due to the size restrictions - but they're
in these folders). These messages cannot be migrated because they
exceed the maximum size Exchange will accept.
