Ah right, when you moved that would have meant that a new account was setup for you. Now what should have happened was that the email mailboxes were migrated across to the new account - a process called Move and Transfer. Do you know if you were offered this or if you were told this needed to be done?
What may have happened is that this process wasn't followed and hence your old email address(es) have become 'orphaned' and as such are liable to be deleted.
Only VM's IT people would be able to sort this out if this is indeed the case, so what I can do is to escalate it and hopefully one of the forum team will respond fairly quickly and get in touch.
