Issue Description : Users’ email list downloads via Threat Explorer may fail to download.
More info : Users may download email lists for a day at a time to lessen the failure probability.
Scope of impact : Your organization is affected by this event, and any user who attempts to download mailing lists from Threat Explorer is impacted.
Current Update : 02/12/2022 09:10:00 AM – Microsoft has deployed and enabled the fix for a set of sample users to further our validation efforts. Once they have fully validated the fix will remediate impact without adverse effects, they will proceed to enable the fix for all users.
Root Cause : A portion of the infrastructure that facilitates the Threat Explorer mailing list export process isn’t responding to requests as expected, which is resulting in download failures.
