    In the last several days, there have been delivery issues with the Direct Delivery phishing test emails. It's been identified that Microsoft was throttling the IPs associated with this tests. They have since put the IPs into an exclusion list, and this should no longer happen. We'll be monitoring it over the next 2 weeks to make sure it's resolved.
