To receive emails for your domain (terramearth.com) in Google Workspace, you need to add the domain to Google Workspace as either a primary, secondary, or alias domain, depending on your organization's requirements. After adding the domain, you must update the Mail Exchange (MX) records at your domain registrar to point to Google's mail servers. This step is essential to ensure that emails are correctly routed to Google Workspace.

Since user accounts are managed in Active Directory (AD) and synced to Google Workspace viaGoogle Cloud Directory Sync (GCDS), the best approach to enforce the new password policy is to create the password policy within Active Directory and then enable password synchronization in GCDS. This ensures that the complex password requirements are enforced within AD, and when passwords are updated, they will be synchronized with Google Workspace, maintaining consistency across both systems.

By creating separateorganizational units (OUs)for each department, you can apply different external sharing settings based on the department's requirements. For example, you can configure the sales and marketing department's OU to allow external sharing, while configuring the engineering department's OU to restrict external sharing. This approach allows you to enforce departmental policies efficiently without impacting other departments.

Google Workspace offers Archived User licenses, which allow you to retain access to the data and communications of former employees without paying for a full user license. This option ensures compliance with the policy of retaining project data and communications in Google Vault while minimizing costs by avoiding unnecessary full user licenses.

To allow the security team to investigate potential security breaches using the security investigation tool, you should create a custom administrator role with Security Center access. This role will provide the security team with the necessary permissions to access and use the security investigation tool without granting them unnecessary permissions, such as those associated with User Management or Super Admin roles. This approach ensures both security and compliance with industry regulations.
