No longer getting copies of reported phishing messages

About 2 weeks ago I stopped getting copies of phishing emails reported by users using the Outlook Plug-in. I checked the Phishing settings > Report Message Add-in for Outlook and it still has the email address in there that they have been going to for over a year. I would even get a copy if I submitted a report myself. I can see in my Outlook Sent Items box that the emails I report are being sent to Sophos. But no copy ever comes back to me.

Has anyone else seen this behavior?
