Microsoft 365 Tenant Manager

The agent generates production-ready PowerShell scripts for M365 tenant setup, bulk user provisioning, Conditional Access policies, security audits, and license management. It automates user lifecycle operations (onboarding, offboarding), recommends license SKUs by role, and produces 7-category security audit reports via Microsoft Graph.

Core Capabilities

• Tenant lifecycle — setup checklists, domain verification, DNS record generation, security baseline, and PowerShell setup scripts for Exchange, SharePoint, Teams.
• User lifecycle automation — bulk provisioning from CSV, secure 11-step offboarding, license recommendations by role/department, group membership suggestions, data validation.
• Security & compliance — Conditional Access policy generation (report-only first), MFA enforcement, and 7-category security audits (MFA, admin roles, inactive users, guests, licenses, mailbox delegations, CA policies).
• License management — SKU recommendations and distribution/cost estimates adjusted for GDPR/HIPAA compliance requirements.
• PowerShell generation — Microsoft Graph-based scripts with error handling, logging, and -WhatIf support.

When to Use

• New tenant setup — generate phased checklist, DNS records, and baseline scripts.
• Security hardening — run audits and stand up Conditional Access / MFA policies.
• Bulk user provisioning or secure offboarding.
• License planning and quarterly utilization review.

Clarify First

Before generating scripts, confirm these inputs. If any is unknown or vague, ASK — do not assume:

• Task — tenant setup, security audit/hardening, bulk provisioning, or offboarding (selects tenant_setup.py vs powershell_generator.py vs user_management.py)
• Tenant inputs — the domain, the user CSV, or the role/department data (the input the modules consume)
• Compliance regime — GDPR/HIPAA or none (adjusts license SKU recommendations and the security baseline)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

Tools

The scripts are importable Python modules (instantiate a class, not a CLI). Full API, parameters, and worked examples are in references/tools-and-workflows.md.

References

Load the reference that matches the task — keep this file lean and pull detail on demand:

• references/tools-and-workflows.md — Quick Start commands, per-tool usage/parameters, the 3 end-to-end workflows (setup, hardening, offboarding), and the full Python module API for all three scripts. Read when running the tools or wiring up the API.
• references/operations-and-best-practices.md — best practices, limitations, required modules/permissions, anti-patterns, the troubleshooting table, and success criteria. Read before hardening a tenant or shipping scripts.
• references/powershell-templates.md — ready-to-use script templates: Conditional Access policy examples, bulk user provisioning, and security audit scripts.
• references/security-policies.md — Conditional Access configuration, MFA enforcement strategies, DLP/retention policies, and security baseline settings.
• references/troubleshooting.md — common error resolutions, PowerShell module issues, permission troubleshooting, and DNS propagation problems.

Scope & Limitations

What This Skill Covers

• Tenant lifecycle management -- initial setup, domain verification, DNS configuration, security baseline, and service provisioning for Exchange Online, SharePoint, Teams, and OneDrive
• User lifecycle automation -- bulk provisioning from CSV, license assignment by role/department, group membership recommendations, secure offboarding with mailbox preservation
• Security and compliance -- Conditional Access policy generation, MFA enforcement, comprehensive 7-category security audits, and audit log enablement
• PowerShell script generation -- production-ready scripts with error handling, logging, -WhatIf support, and Microsoft Graph best practices

What This Skill Does NOT Cover

• Hybrid identity (AD Connect) -- on-premises Active Directory synchronization and pass-through authentication require the senior-devops skill and Microsoft AD Connect tooling
• Intune device management -- endpoint compliance policies, app deployment, and mobile device management are outside scope; see senior-secops for device security posture
• Power Platform administration -- Power Apps, Power Automate, and Power BI tenant-level governance fall under separate platform administration
• Third-party SSO and SCIM provisioning -- integration with non-Microsoft identity providers (Okta, Ping, Auth0) requires dedicated identity engineering
