Protecting Microsoft 365 Groups

When an email is sent to a Microsoft 365 Group, every member in the group receives the email and the email will also be available in the mailbox assigned with the Microsoft 365 Group.

When a malicious email is sent to a Microsoft 365 Group, Harmony Email & Collaboration detects and quarantines the malicious email from every group member's individual mailbox.

However, the malicious email gets quarantined from the Microsoft 365 Group mailbox only when the policy is set to Prevent (Inline) mode.

Note - Harmony Email & Collaboration supports to protect these groups:

  • Microsoft 365 Groups

  • Mail-enabled Security Groups

  • Distribution groups
