Tip: Try running a user management script on both Windows and Linux. You will see identical results and output.

You gain a unified approach to Microsoft 365 Administration. This reduces errors and makes your automation predictable.

JSON-First Output for Auditing

You need clear records of your actions. The Microsoft 365 CLI gives you JSON output by default. JSON is easy to read, process, and store. You can send this output to dashboards, SIEM tools, or audit logs. You do not need to convert CSV files or parse text manually.

• You can pipe JSON output directly into Power BI, Splunk, or Log Analytics.

• You create audit trails that show exactly what changed and when.

• You improve your compliance posture with detailed, structured logs.

Note: JSON output helps you meet audit requirements and respond quickly to security reviews.

Here is an example of a CLI command and its JSON output:

m365 user list --output json

[
  {
    "id": "user1@contoso.com",
    "displayName": "Alex Lee",
    "role": "User"
  },
  {
    "id": "admin@contoso.com",
    "displayName": "Jordan Smith",
    "role": "Administrator"
  }
]

You can use this data for reporting, monitoring, or compliance checks. This approach makes Microsoft 365 Administration safer and more transparent.

      - name: Upload Audit Log
        uses: actions/upload-artifact@v3
        with:
          name: user-audit
          path: users.json

You create repeatable, reviewable workflows. You improve security and governance for Microsoft 365 Administration.

Getting Started with Microsoft 365 CLI

Installation and Setup

You can install the Microsoft 365 CLI on any major operating system. The CLI uses Node.js, so you need to have Node.js version 18 or later installed first. You can check your Node.js version by running:

node --version

If you need to install Node.js, visit the official Node.js website and download the latest version for your system.

Once Node.js is ready, you can install the CLI globally with a single command:

npm install -g @pnp/cli-microsoft365

After installation, verify that the CLI works by running:

m365 version

You should see the version number displayed. Now you are ready to use the CLI for Microsoft 365 Administration tasks on Windows, macOS, or Linux. You can also use the CLI in containers or cloud-hosted runners for automation.

You have several ways to authenticate with the Microsoft 365 CLI. Each method offers different advantages. The table below summarizes the main options:

For most automation and scripting, use a service principal or managed identity. These methods help you follow the principle of least privilege and avoid sharing personal credentials. Service principals let you control exactly which permissions your scripts have.

Starting in September 2025, Microsoft will require multi-factor authentication (MFA) for user identities in Microsoft Entra ID when using command-line tools. This change will not affect service principals or managed identities. Plan your automation to use workload identities for long-term security and compliance.

Note: Always assign only the permissions your scripts need. Store secrets in secure vaults, such as Azure Key Vault or GitHub Secrets, and rotate them regularly.

Key Administrative Tasks with CLI

User and Group Management

You manage users and groups every day. The Microsoft 365 CLI helps you complete these tasks quickly. You add new users, update group memberships, and remove accounts with simple commands. You do not need to switch between admin centers or learn different tools.

Here are common user and group management tasks you can automate:

• Add users to Microsoft 365

• Update user details, such as display name or role

• Assign users to groups

• Remove users from groups

• List all users and groups in your organization

You run commands like these:

m365 user add --userName "jane.doe@contoso.com" --displayName "Jane Doe"
m365 group add --name "Marketing Team"
m365 group user add --groupName "Marketing Team" --userName "jane.doe@contoso.com"

Tip: You export user and group lists to JSON for easy reporting or bulk updates.

You save time and reduce errors by using the CLI for user and group management. You also create repeatable processes that help your team work more efficiently.

SharePoint and Teams Operations

You often manage SharePoint sites and Teams. The CLI gives you a unified way to handle these tasks. You create new sites, update settings, and manage permissions without leaving your terminal.

Common SharePoint operations include:

Automating Workflows in Microsoft 365 Administration

Scripting and Bulk Operations

You can automate many Microsoft 365 tasks with the CLI. Scripting helps you handle repetitive work, such as user provisioning or group management, with speed and accuracy. You start by installing the CLI and connecting to Microsoft Graph. This connection gives you access to all your Microsoft 365 resources.

1. Install and connect: Set up the CLI and authenticate with Microsoft Graph.

2. Create users in bulk: Use a CSV file to import many users at once. This method saves time when onboarding new employees.

3. Verify results: Check user creation in the Admin Center to confirm your script worked as expected.

Tip: Automate daily tasks like user provisioning and backups with minimal code. This approach increases your efficiency and reduces manual errors.

You gain several benefits from scripting and bulk operations:

• Efficiency: Complete tasks faster and free up time for other work.

• Integration: Use the CLI across different Microsoft platforms, which improves your DevOps workflows.

• Scalability: Run commands on multiple machines at once, so you do not repeat steps manually.

• Consistency: Automation lowers the risk of mistakes and helps you meet security standards.

CI/CD Pipeline Patterns

You can take automation further by integrating the CLI into your CI/CD pipelines. This setup lets you run scripts automatically when you push changes or on a schedule. You use tools like GitHub Actions, Azure DevOps, or GitLab CI to trigger these workflows.

A typical CI/CD pipeline for Microsoft 365 administration might include:

• Installing the CLI on the runner

• Authenticating securely with a service principal or managed identity

• Running scripts to create users, update groups, or generate reports

• Storing output in JSON for audit or compliance needs

- name: Install Microsoft 365 CLI
  run: npm install -g @pnp/cli-microsoft365
- name: Bulk Import Users
  run: m365 user import --csv users.csv

Note: CI/CD integration ensures your workflows are repeatable, reviewable, and secure. You reduce manual effort and improve reliability across your organization.

Security and Governance with CLI

Safe Authentication Methods

You need strong authentication to protect your Microsoft 365 environment. The CLI supports several secure methods that help you reduce risk and improve compliance. You can choose the method that fits your workflow and security requirements.

The table below compares the most secure authentication options available for Microsoft 365 CLI. Each method uses a different strategy to keep your data safe.

You can use MFA to add an extra layer of security. Passwordless MFA removes the need for passwords, which helps you avoid common threats like phishing. Phishing-resistant MFA uses hardware keys or biometric verification, making it very hard for attackers to gain access.

Tip: Always choose the strongest authentication method available for your automation scripts. Store credentials in secure vaults and rotate them regularly.

Guardrails and Scoped Commands

You want to avoid mistakes that could impact your entire tenant. The CLI provides guardrails that help you run commands safely. You can scope commands to specific users, groups, or sites. This approach limits the impact of your actions and supports the principle of least privilege.

• Use filters to target only the resources you need to change.

• Test scripts with preview or dry-run modes before applying changes.

• Assign permissions only to service principals or managed identities that need them.

For example, you can run a command that updates only one group instead of all groups:

m365 group set --groupName "Marketing Team" --description "Updated description"

Note: Scoped commands and guardrails help you maintain control and prevent accidental changes. You build safer workflows and support your organization's governance policies.

You improve security and governance by using safe authentication and scoped commands. The CLI helps you automate tasks without compromising your environment.

Common Pitfalls and Solutions

Permission Risks and Bulk Operations

You might feel tempted to grant broad permissions to your automation scripts for convenience. This approach can create security risks. Over-permissioned service principals or user accounts can make your environment vulnerable to accidental or malicious changes. Bulk operations, such as updating all users or deleting multiple groups, can also cause widespread impact if you do not use filters or previews.

How to avoid these risks:

• Apply least privilege: Assign only the permissions your script needs. Avoid using global admin accounts for automation.

• Use filters and scoped commands: Always target specific users, groups, or sites. For example, use --filter options to narrow your changes.

• Test with dry-run or preview modes: Run your scripts in a test environment or use preview features to see the impact before applying changes.

• Review scripts before running: Ask a colleague to review your automation scripts, especially for bulk tasks.

Tip: Always double-check your command scope. A small typo can affect hundreds of users.

Secret Management and Environment Drift

You need to manage secrets, such as client IDs and passwords, for service principals or automation accounts. Storing these secrets in plain text or sharing them in chat can expose your environment to attacks. Environment drift happens when different machines or pipelines use different CLI versions or configurations, leading to inconsistent results.

Best practices for secret management and consistency:

• Store secrets securely: Use tools like Azure Key Vault, GitHub Secrets, or Azure DevOps Library. Never hard-code secrets in scripts.

• Rotate secrets regularly: Change passwords and keys on a schedule to reduce risk.

• Pin CLI versions: Specify the CLI version in your automation to ensure consistent behavior across environments.

• Document your setup: Keep a record of your CLI configurations and dependencies. This helps you troubleshoot and onboard new team members.

Note: Secure secret management and consistent environments help you avoid unexpected failures and keep your Microsoft 365 tenant safe.

When to Use PowerShell Instead

Specialized Scenarios and Legacy Needs

You may find that Microsoft 365 CLI covers most daily administration tasks. However, some situations still require PowerShell. These cases often involve specialized needs or legacy systems that demand deeper control.

PowerShell gives you access to advanced features and legacy support. You can manage older applications that need authentication methods not available in modern tools. You also gain the ability to customize security policies beyond the defaults. Some organizations need to apply unique security rules or handle complex tenant configurations. PowerShell lets you adjust these settings with precision.

Here is a table that highlights when PowerShell becomes essential:

You might need PowerShell if you work with legacy systems or require custom security controls. For example, some older applications do not support modern authentication. PowerShell allows you to configure these settings and maintain compatibility.

Note: PowerShell remains the best choice for tasks that demand granular control or support for legacy environments.

You should use Microsoft 365 CLI for most routine and cross-platform tasks. Switch to PowerShell when you need advanced options or must support older systems. This approach helps you balance efficiency with flexibility.

• Use CLI for repeatable, automated workflows.

• Choose PowerShell for specialized, legacy, or highly customized scenarios.

You can combine both tools to create a robust administration strategy. This method ensures you meet all your organization’s needs, from modern automation to legacy support.

Quick Pilot: Proving Value in 30 Minutes

Bulk Task Automation Example

You can prove the value of Microsoft 365 CLI with a quick pilot. Choose a common bulk task, such as adding users to multiple Teams. This task often takes a long time if you do it manually. With the CLI, you automate the process and save time.

Start by preparing a CSV file with user emails and team names. The CLI reads this file and adds each user to the correct team. Here is a sample workflow:

1. Prepare your CSV file
   Create a file named bulk-add.csv with columns for user and team.

   user,team
   alice@contoso.com,Marketing
   bob@contoso.com,Sales
   

2. Run the CLI command
   Use the following command to add users in bulk:

   m365 teams member add --csv bulk-add.csv
   

3. Export results to JSON
   Save the output for auditing:

   m365 teams member list --output json > team-members.json
   

Tip: Always test your script with a small group before running it on all users.

Review and Adoption Steps

After you complete the pilot, review the results. Check the JSON output to confirm that users joined the correct teams. Share the results with your team and ask for feedback.

Follow these steps to adopt the CLI for ongoing operations:

• Document the process and share the script with your team.

• Store the script in your version control system.

• Schedule regular reviews to update the script as your needs change.

• Use the CLI in your CI/CD pipeline for repeatable automation.

You build trust in automation by starting small and scaling up. The CLI helps you create safe, repeatable workflows for Microsoft 365 Administration.

You can transform Microsoft 365 Administration by using the Microsoft 365 CLI. This tool helps you automate tasks safely and consistently across any platform. Before you start, follow these steps to maximize your results:

1. Audit and clean up permissions in SharePoint, OneDrive, and Teams.

2. Enforce least privilege access by reviewing group memberships and sharing settings.

3. Review licensing differences for data protection and visibility.
