## Introduction

Activating your Office 365 product key is an essential step to unlock all the features and benefits of this powerful productivity suite. Whether you’ve purchased a new subscription or received a key through your organization, this guide will walk you through the activation process step by step.

## What is an Office 365 Product Key?

4. System requirements met for Office 365

## Step-by-Step Activation Process

### Step 2: Enter Your Product Key

Once logged in, you’ll be prompted to enter your Office 365 key. Type it carefully, paying attention to:
– Capitalization (though most keys aren’t case-sensitive)
– Distinguishing between similar characters (0 vs O, 1 vs I, etc.)

### Step 3: Verify Your Subscription

After entering the key, Microsoft will verify your subscription type and duration. Confirm that the details match what you purchased.

### Step 5: Activate After Installation

Once installed:

2. Click on “Activate” if prompted
3. Sign in with the same Microsoft account used during setup
4. Your software should now be fully activated
