# Microsoft 365 PowerShell Scripts

A collection of PowerShell scripts and tools, in varying stages of completion, for managing, auditing, and reporting on Microsoft 365 tenants. The collection spans Entra ID (Azure AD), Exchange Online, SharePoint/OneDrive, Teams, Intune, Microsoft Defender, Purview/compliance, and the Power Platform.

This collection is in active development, and the scripts are at different stages of completion. Some are functional reporting tools that query live Microsoft 365 data; some are partially implemented (they retrieve real data for parts of the report and use sample values for others); and some are placeholders whose reporting logic is scaffolded but not yet connected to live data (they currently emit sample output). The **Status** column in the Script Index shows where each script stands.

> Scripts are provided as-is. Review and test each one before running in production.

## Overview

This repository provides 76 reporting and auditing scripts (numbered `00`-`75`) for Microsoft 365 administrators, in varying stages of completion. Completed scripts typically read tenant configuration or activity data and export a CSV report, making them suitable for scheduled reporting, security reviews, and compliance audits. Other scripts are partially implemented or are placeholders pending implementation.

The scripts are intended for M365 administrators, security/compliance teams, and consultants who want repeatable, script-based reporting. Because not every script is complete, review each script's status and source before use.

## Prerequisites

- **PowerShell 5.1** or **PowerShell 7+**. PowerShell 7+ is recommended.
- The relevant Microsoft modules installed, depending on which scripts you run:
  - **Microsoft Graph PowerShell SDK** (`Microsoft.Graph.*`) - used by many of the scripts.
  - **Exchange Online Management** (`ExchangeOnlineManagement`) - used by the Exchange and several compliance scripts (also provides `Connect-IPPSSession`).
  - **Microsoft Teams** (`MicrosoftTeams`), **SharePoint Online** (`Microsoft.Online.SharePoint.PowerShell`), **Power BI** (`MicrosoftPowerBIMgmt`), **Power Platform** (`Microsoft.PowerApps.Administration.PowerShell`), and Intune modules for the scripts that target those services.
- Appropriate Microsoft 365 administrative roles and, where noted, the required licensing (for example, some Identity Protection and Privileged Identity Management data requires the appropriate Microsoft Entra ID licensing).

Script `00-Install-M365Modules.ps1` is provided to help install required modules.

## Authentication & Permissions

Scripts authenticate using the connection method appropriate to the service they target - for example `Connect-MgGraph` (Microsoft Graph), `Connect-ExchangeOnline`, `Connect-IPPSSession` (Security & Compliance), `Connect-MicrosoftTeams`, `Connect-SPOService`, `Connect-PowerBIServiceAccount`, or `Add-PowerAppsAccount` (Power Platform). The Script Index lists the connection method observed in each script's source.

Where a script includes comment-based help, it documents the specific permissions it requests; run `Get-Help .\<script>.ps1 -Full` to review them. For scripts that do not yet have help, review the script source directly before running so you can confirm the requested access is appropriate for your environment.

## Installation

```powershell
# 1. Clone the repository
git clone https://github.com/Ryan-Adams57/Microsoft-365-PowerShell-Scripts.git
cd Microsoft-365-PowerShell-Scripts

# 2. Install the required modules
.\00-Install-M365Modules.ps1
```

## Usage

View a script's full help (where comment-based help is present):

```powershell
Get-Help .\01-Get-M365UserLicenseReport.ps1 -Full
```

Run a script (you will be prompted to sign in and consent to the requested scopes):

```powershell
.\01-Get-M365UserLicenseReport.ps1 -ExportPath "C:\Reports\UserLicenses.csv"
```

Parameter names may vary per script. Check `-Full` help where available, or the script source, for the exact parameters a given script supports.

## Script Index

The repository contains **76 scripts** (`00`-`75`). The **Status** column indicates each script's current stage of completion.

**Status legend:**

- **Functional** - queries live Microsoft 365 data and produces a real report.
- **Partial** - retrieves real data for part of the report; some fields use sample/placeholder values pending implementation.
- **Placeholder** - the script contains scaffolding or sample output, but the reporting logic is not currently retrieving the intended live data.
- **Utility** - helper script (e.g., module installer).

> Functional status is based on source-code review confirming live data-retrieval logic. Scripts have not been individually validated against every Microsoft 365 tenant configuration.

The "Connects via" values reflect the connection method observed in each script's source. For Placeholder scripts, this is the method the script is scaffolded to use once implemented.

## Repository Structure

Scripts are stored in the repository root and numbered `00`-`75` so they sort in a logical order. Numbers `1`-`9` are zero-padded (`01`-`09`) for correct sorting. The numbering roughly groups related areas together (identity and licensing early on, followed by Exchange, Teams, Intune, Defender, Purview/compliance, and Power Platform).

- `00-Install-M365Modules.ps1` - module installer helper.
- `01`-`75` - individual reporting/auditing scripts (see the Status column for completion state).
- `README.md` - this file.
- `LICENSE` - repository license.

## Known Issues

- **Resolved:** Duplicate/extra header comment lines ("extra slashes") in scripts 42-50 have been removed.
- **Resolved:** `12-Get-M365RiskySignInsReport.ps1` now includes full comment-based help.
- **In progress:** Several scripts are placeholders whose reporting logic is scaffolded but not yet connected to live data - they currently produce sample output. A few others are partially implemented. See the **Status** column in the Script Index for the current state of each script. Implementing these is the focus of the next phase of work.
- Comment-based help is still being added across the functional scripts (currently only script 12 has it).
- Validate each script in a non-production tenant before relying on it.

## Contributing

Contributions and feedback are welcome:

- Open an **issue** to report a bug, request a script, or suggest an improvement. Please include the script name and any error output.
- Submit a **pull request** for fixes or enhancements. Keep changes focused, and note any new permissions a script requires.

## Acknowledgements

This repository has benefited from thoughtful community feedback. Special thanks to:

**[Snickasaurus](https://github.com/Snickasaurus)** - provided multiple suggestions that directly improved the repository, including:

- Recommending the creation of `00-Install-M365Modules.ps1` to consolidate module installation across all scripts.
- Advising zero-padding of scripts 1-9 for proper sorting.
- Highlighting that `12-Get-M365RiskySignInsReport.ps1` was a template and suggesting clarification.
- Noting formatting issues (extra slashes) in scripts 42-50.
