Send as permission on Exchange

I have applied send as permissions and full access  to user1 mailbox from user2. When I try to send an email from user2 account using user1 email it fails  with:"You can't send a message on behalf of this user unless you have permission to do so. Please make sure you're sending on behalf of the correct sender, or request the necessary permission"
