How to Activate Microsoft Project with Your Product Key
Activating Microsoft Project is essential to unlock all features and remove trial limitations. Whether you purchased Project 2024, 2021, or 2019, the activation process links your license to your Microsoft account and verifies your software is genuine.
This comprehensive guide covers all activation methods: online activation for the fastest experience, phone activation for computers without internet access, and volume licensing for enterprise deployments. We'll also show you how to verify your activation status and troubleshoot common issues.
Understanding Product Key Activation
Before activating, understand the key concepts:
What is a Product Key?
A 25-character alphanumeric code (format: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX) that proves you purchased a legitimate license. It's case-insensitive but must be entered exactly.
Retail vs Volume License Keys
Retail keys are for individual purchases and activate online. Volume License keys (MAK or KMS) are for organizations with multiple installations.
Microsoft Account Linking
When you activate, the license links to your Microsoft account. This lets you reinstall Project on the same PC or transfer to a new computer without the original key.
One Key, One Device
Each retail product key activates Project on one computer. Installing on additional devices requires additional licenses.
Method 1: Online Activation (Recommended)
Online activation is the fastest and most reliable method. It requires an internet connection and takes just seconds.
Launch Microsoft Project
Open Microsoft Project from the Start menu or desktop shortcut. If this is the first launch, you'll see an activation prompt automatically.
Sign In to Your Microsoft Account
Click Sign In and enter your Microsoft account email and password. This links the license to your account for future reference.
Enter Your Product Key
When prompted, enter your 25-character product key. You can find this on your purchase confirmation, product card, or email receipt. Type carefully—there's no difference between uppercase and lowercase.
Click Activate
Click the Activate button. Project will connect to Microsoft's activation servers and verify your key. This typically takes 5-30 seconds.
Activation Complete
You'll see a confirmation message that Project is activated. Your license is now linked to your Microsoft account.
Alternative: If Project didn't prompt you automatically, go to File → Account → Activate Product and follow the same steps.
Method 2: Phone Activation
Use phone activation when your computer doesn't have internet access or if online activation fails repeatedly.
Open Activation Wizard
In Project, go to File → Account → Activate Product. If online activation fails, you'll see an option for telephone activation. Click "I want to activate by telephone."
Select Your Country
Choose your country or region from the dropdown list. This determines which toll-free activation number to call.
Call the Activation Number
Call the toll-free number displayed. You'll reach an automated system (or a representative for complex cases).
Provide Installation ID
The wizard displays a long Installation ID (usually 54 digits in groups). Read this to the automated system using your phone keypad or voice.
Enter Confirmation ID
The system will give you a Confirmation ID. Enter this into the activation wizard exactly as provided.
Complete Activation
Click Activate to complete the process. Your Project is now activated without needing internet.
Common Phone Activation Numbers
Phone activation is available 24/7 through the automated system. For complex issues, you may be transferred to a support representative during business hours.
Method 3: Volume Licensing Activation (Enterprise)
Organizations with volume licenses use either KMS (Key Management Service) or MAK (Multiple Activation Key) methods.
KMS Activation
KMS activation requires a KMS server on your network. Computers automatically activate when connected to the corporate network.
- Ensure your computer is connected to the corporate network
- Open Command Prompt as Administrator
- The KMS client key is typically pre-configured in volume license media
- Project should activate automatically when it detects the KMS server
- Activation renews every 180 days while connected to the network
MAK Activation
MAK keys allow a limited number of one-time activations. Once activated, the license is permanent on that device.
Open Command Prompt as Administrator
Right-click the Start button and select "Command Prompt (Admin)" or "Windows Terminal (Admin)".
Navigate to Office Directory
Type: cd "C:\Program Files\Microsoft Office\Office16" (adjust path for your installation)
Enter MAK Key
Type: cscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX (replace with your MAK key)
Activate
Type: cscript ospp.vbs /act
Verify Activation
Type: cscript ospp.vbs /dstatus to confirm activation status
Command Line Activation Methods
Advanced users and IT administrators can activate Project using command line tools:
Using OSPP.VBS (Office Software Protection Platform)
cscript ospp.vbs /inpkey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXXInstall product keycscript ospp.vbs /actActivate Office/Projectcscript ospp.vbs /dstatusDisplay activation statuscscript ospp.vbs /unpkey:XXXXXRemove product key (last 5 chars)Using SLMGR (Software License Manager)

Navigate to the Office installation directory first (typically C:\Program Files\Microsoft Office\Office16).
How to Verify Activation Status
Confirm your Project installation is properly activated:
Method 1: Through Project Interface
Open Project → File → Account. Look for "Product Activated" under Product Information. You'll see your license type and linked Microsoft account.
Method 2: Using Command Prompt
Open Command Prompt as Admin, navigate to Office directory, and run: cscript ospp.vbs /dstatus. This shows detailed activation information including remaining days (for subscriptions) and license type.
Method 3: Check for Activation Prompts
An activated copy won't show activation reminders, trial expiration warnings, or feature limitations. If you see these, activation may have failed.
Signs of Successful Activation
- "Product Activated" message in File → Account
- No activation watermarks or banners
- All features accessible without limitations
- Your Microsoft account shown under product info
- No recurring activation prompts
How to Transfer Your License to a New PC
Moving to a new computer? You can transfer your retail Project license:
Deactivate on Old PC
On your old computer, go to File → Account → Sign out of your Microsoft account. Then uninstall Project completely via Settings → Apps.
Install on New PC
Download Project from account.microsoft.com using the same Microsoft account that holds your license.
Sign In and Activate
Sign in with your Microsoft account. If the license was properly linked, Project should activate automatically. If prompted, enter your product key again.
Important: Retail licenses can be transferred, but OEM licenses (pre-installed by manufacturer) cannot be transferred to a different computer. Volume licenses have specific transfer rules defined by your organization's agreement.
Troubleshooting Activation Issues
Error: Product Key Already in Use
Each key works on one PC. If you're reinstalling on the same computer, sign in with the Microsoft account used originally. If installed elsewhere, deactivate that installation first or contact Microsoft Support.
Error: Invalid Product Key
Double-check the key for typos (0 vs O, 1 vs I, etc.). Ensure you're entering a Project key (not Windows or other Office product). Verify the key matches your installed version (Project 2024 key for Project 2024).
Error: Unable to Connect to Activation Server
Check your internet connection. Temporarily disable firewall/antivirus. Try again later—servers may be busy. Use phone activation as an alternative.
Error: Activation Limit Reached
You've activated on too many devices. Contact Microsoft Support to reset activation count or purchase additional licenses.
Project Shows "Unlicensed Product"
Go to File → Account → Update License. Sign in with your Microsoft account. If still unlicensed, repair Office installation via Settings → Apps → Microsoft Office → Modify → Repair.
KMS Activation Failing
Ensure network connectivity to KMS server. Verify KMS server is properly configured. Check that your computer's clock is synchronized. Contact IT administrator for KMS server status.
Phone Activation Confirmation ID Not Working
Ensure you entered all digits correctly with no extra spaces. The Confirmation ID is case-sensitive in some regions. Try requesting a new Confirmation ID.
License Deactivated After Hardware Change
Major hardware changes (motherboard, CPU) may trigger reactivation. Use online or phone activation to reactivate. Your license remains valid despite hardware changes.
