MC226549 – Compliance Manager: Announcement of release to GCC cloud

Microsoft 365 Roadmap ID 67132.

In mid-September (Roadmap IDs 60771) we announced (MC222630 and MC222638) that Compliance Manager solution was available via the Worldwide/Multi-tenant cloud. We are now pleased to announced Compliance Manager availability in the GCC cloud.

MC226683 – Secure by Default – Honoring EOP/ATP detonation verdicts

We're making some changes to how tenant (Anti-spam/Hosted Content Filter policy) and user (Safe sender) allows work when it comes to high confidence phish. A message is marked with the high confidence phish verdict when we detonate it and know that it is malicious. We want to ensure that our customers are protected and therefore block those messages from getting to the inboxes of end-users. This is normally the case, but tenant and user overrides can stop this from happening. We have decided to no longer honor Allowed senders or domains when the messages are considered as high confidence phish.

 Key Points:

  • Timing: Beginning mid-December through the end of January 2021
  • Action: Review and assess impact

Secure by default in Office 365


MC226539 – Updates to ‘Records Management’ default role group in Security

To simplify the permissions management of the new Records Management solution, we will be updating the configuration of the ‘Records management’ role group in the Security & Compliance Center. The updates will add additional roles to this role group to manage all facets of the Records Management solution including disposition review.

 When this will happen?

We will roll out this update starting on December 14th, 2020.


MC226863 – Azure SSL/TLS certificate changes

In early November, DigiCert replaced the certificate of an Intermediate Certificate Authority (ICA) which issues SSL/TLS certificates used by Azure Active Directory (Azure AD) services, such as Microsoft 365 and Dynamics 365, in the Public and US Government Clouds. In most cases, no action is required. However, if you explicitly hard code (i.e. “pin”) the ICA certificates to be trusted or have custom solutions that depend on storing ICA certificates in a trust store, you will need to take action as soon as possible in order to avoid service disruptions.
