The AcceptMessagesOnlyFrom parameter specifies who is allowed to send messages to this recipient. Messages from other senders are rejected.
It looks like it is A like potpal says. by email would assume that we want the user to be allowed to send emails to the public folder.
Im not sure, the AcceptMessagesOnlyFrom is in set-mailbox as well and public folders in 2013 are just mailboxes, a case could be made for C. Labbing it out right now.
Nevermind, set-mailbox would stop mail for all folders in that database
So all you agree it is A????
