Were the emails sent , or were they bounced back at the sender?  Maybe the emails never arrived.

Do you have third party spam filtering that stopped the emails?  Look in the spam quarantine.

Those are the two predominant reasons why you would not get email.

Does your firewall include grey listing? You need to track through the firewall logs as it does not appear to be an Exchange issue (unless the firewall is putting in a different folder).

Check that the messages are still not queuing for delivery, see the Exchange Queue Management console and point it to each of the Hub Transport servers to view the queues on each server.
