Checking license status and activation for Microsoft Office prevents unexpected feature restrictions and ensures you can use all Office applications without interruptions. Whether you use Microsoft 365 Apps, Office 2021, or earlier versions, there are multiple ways to confirm both license type and activation status. The most reliable method depends on your Office version and installation type.

Check Activation Status and License Type from Office Application

Open any Microsoft Office application, such as Word, Excel, or PowerPoint. This method works for most Office versions, including Microsoft 365 Apps and perpetual licenses like Office 2021 or Office 2019.

Select File in the top menu, then choose Account or Office Account, depending on your Office version.

In the “Product Information” section, look for a message indicating the activation status. If you see Product Activated, your Office installation is fully activated. If you see Product Activation Required or similar, your Office needs activation.

Review the product name and license type (for example, Microsoft 365 Subscription, Office Home & Business 2021, or Office Professional Plus 2019). This helps you identify whether you have a subscription or a perpetual (one-time purchase) license.

Check Activation Status Using Command Prompt and OSPP.VBS Script

For detailed technical information about your Office license, especially on perpetual or volume-licensed installations, you can use the ospp.vbs script included with Office.

Open Command Prompt as an administrator. To do this, type cmd in the Windows search bar, right-click on Command Prompt, and select Run as administrator.

Navigate to the Office installation directory. For 64-bit Office on 64-bit Windows, enter:

cd "C:\Program Files\Microsoft Office\Office16"

For 32-bit Office on 64-bit Windows, use:

cd "C:\Program Files (x86)\Microsoft Office\Office16"

Replace Office16 with the correct folder for your Office version (e.g., Office15 for Office 2013, Office14 for Office 2010).

Run the following command to display license and activation details:

cscript ospp.vbs /dstatus

This command outputs detailed information, including:

Product ID and SKU ID.
License name and description (such as Retail, Volume, MAK, or KMS).
Activation status (e.g., LICENSED, NOTIFICATIONS, or OOB_GRACE).
Remaining grace period for volume licenses.
Last five characters of the installed product key.

If the license is listed as LICENSED, Office is activated. If you see statuses like NOTIFICATIONS or OOB_GRACE, activation is incomplete or expired, and Office features may be limited.

For Microsoft 365 Apps installed after Version 1910, the ospp.vbs script no longer provides complete information. Use the PowerShell method below for those installations.

Check Activation Status with PowerShell and vnextdiag.ps1 (Microsoft 365 Apps and Office 2021+)

Microsoft 365 Apps and newer versions of Office (including subscription-based Project and Visio) use a new activation method. The vnextdiag.ps1 PowerShell script is the recommended way to retrieve license and activation status for these products.

Open Windows PowerShell as an administrator. Search for PowerShell in the start menu, right-click, and choose Run as administrator.

Navigate to the Office installation directory. For 64-bit Office, use:

cd "C:\Program Files\Microsoft Office\Office16"

For 32-bit Office on 64-bit Windows:

Run the diagnostic script to list license and activation details:

.\vnextdiag.ps1 -action list

The script outputs:

Type of license (e.g., User|Subscription, Device|Perpetual).
Product name (e.g., O365ProPlusRetail, HomeBusiness2021Retail).
Activation state (Licensed, Not Licensed, etc.).
User email associated with activation, if applicable.
Tenant ID for organizational subscriptions.
Details about shared computer activation or device-based licensing.

If the license state is Licensed, your Office is activated. If no licenses are found or the status is different, activation is needed or has failed.

Note: If PowerShell script execution is restricted, temporarily allow scripts in your session with: Set-ExecutionPolicy RemoteSigned -Scope Process.

You can also check for activated products in the Windows Registry or by examining license files in the %localappdata%\Microsoft\Office\Licenses folder, but using vnextdiag.ps1 is faster and more reliable for supported versions.

Check License Type and Status with PowerShell CIM Commands

For advanced users or system administrators managing multiple machines, PowerShell can query license status locally or remotely using Windows Management Instrumentation (WMI).

Open PowerShell as an administrator.

Run the following command to list Office licenses and their status:

Get-CimInstance SoftwareLicensingProduct | where {$_.name -like "*office*"} | select name, licensestatus

The LicenseStatus value indicates:

0 = Unlicensed.
1 = Licensed.
2 = Out of Box Grace Period.
3 = Out of Tolerance Grace Period.
4 = Non-Genuine Grace Period.
5 = Notification.
6 = Extended Grace.

You can convert these codes to descriptive text using a custom enumeration in PowerShell for easier interpretation.

To check activation on a remote computer, use:

Get-CimInstance -ComputerName [RemotePCName] SoftwareLicensingProduct | where {$_.name -like "*office*"} | select name, licensestatus

Check License Status from Control Panel (Windows)

The Control Panel provides a basic check for Office activation, but it may not display detailed license type information.

Open the Windows Control Panel and go to Programs > Programs and Features.

Find Microsoft Office in the program list. If it is marked as “Product Activated,” activation is complete. If not, consider using one of the other methods above for more details.

Check Activation Status on Mac

For Mac users, activation checks are slightly different.

Open any Office application (such as Word or Excel).

In the application menu at the top of the screen, select Help > Check Activation.

If a message appears confirming that the product is activated, your Office license is active. If not, follow the prompts to activate or troubleshoot.

Troubleshooting and Additional Notes

If you discover that your Office license is not activated, try restarting your computer and ensuring a stable internet connection. For subscription licenses, sign in with the correct Microsoft account. If you purchased your license through an authorized reseller and activation fails, contact their support team for help. For volume or enterprise licenses, coordinate with your IT department or system administrator to resolve activation or assignment issues.

Activation status can also be affected by system cloning (identical SIDs), leftover registry keys from previous installations, or exceeding the allowed number of activations for your license type. Use the most appropriate method above based on your Office version and deployment scenario to get accurate results.

Verifying your Microsoft Office license type and activation status ensures you have access to all features and prevents interruptions. Use the built-in Office interface for quick checks, or command-line and PowerShell tools for more detailed information and troubleshooting.
