Adding a New Domain to Microsoft 365

At times, organizations might add new domains to their Microsoft 365 account.

To provide continuous protection for the users in these domains using Harmony Email & Collaboration, these users must not have policies with Protect (Inline) protection mode for the first 48 hours after the transition.

To do that:

• For all the existing policies (Threat Detection, DLP and Click-Time Protection) that are in Protect (Inline) protection mode, change the scope to exclude the users from the new domain.

• For the users in the new domain, assign new policies with Detect and Remediate protection mode.

Note - After 48 hours from the transition, you can change the policy scope so that it protects all domains in the Protect (Inline) protection mode.

If you have any queries about how to apply these changes in the configuration, contact Check Point Support.
