it sounds like your user is sending a shortcut as an attachment to someone else. i don't know how exactly they're doing it but they need to restore the message first in order for the recipient to be able to open it.

Andrew is correct, if a user drags and drops an archived email to a new email, then it is the archived item which is sent. That's no use to people who don't have access to the person's archive.. internally in the organisation or externally.
The end user can :
* Reply to the mail they want to attach
* Forward it, even multiple emails work
* Restore the items
* Open the item and copy and paste 'parts' of it in to a new email
