Question details

The user needs a confirmation ID and requires clarification regarding the activation process for a product described as Microsoft 365 2016.

Product: Microsoft Office 2016 / Microsoft 365
Device & OS: not provided
Scenario: Attempting to activate Microsoft Office software and requesting a confirmation ID.
Observed behavior: The user is experiencing confusion between the perpetual Office 2016 license and the Microsoft 365 subscription service, hindering successful activation.

Before you start

Before proceeding, sign in to your Microsoft account online and navigate to 'Services & subscriptions' to verify whether you own a one-time purchase of Office 2016 or an active Microsoft 365 subscription.

Solution 1Recommended

Determine Office version and activate via telephone

Use this method to obtain your Confirmation ID through Microsoft's telephone activation system once you have confirmed your specific Office version.

Office 2016 is a perpetual (one-time purchase) license, whereas Microsoft 365 is a subscription-based service. The activation prompts will differ based on the license attached to your Microsoft account. If online activation fails, the telephone method can generate the required Confirmation ID.

Check your Office version

Open any Office application such as Word, click on 'File' in the top left corner, and select 'Account'. Look under 'Product Information' to see if it displays Office 2016 or Microsoft 365.

Launch the Activation Wizard

If your software is not activated, an Activation Wizard will appear. Select the option that says 'I want to activate the software by telephone' and click 'Next'.

Get the Confirmation ID

Select your country or region. Call the toll-free number provided on the screen, input the displayed Installation ID into the automated phone system, and type the Confirmation ID provided by the system into the wizard.

Keep your Installation ID ready: The automated phone system will require the long Installation ID displayed in step 2 of the Activation Wizard. Have a pen and paper ready to write down the Confirmation ID.

Solution 2

Use the Microsoft Support and Recovery Assistant (SaRA)

If standard activation fails or you are confused about which version is installed, use Microsoft's automated troubleshooting tool to diagnose and fix license conflicts.

Frequently Asked Questions

What is the difference between Office 2016 and Microsoft 365?

Office 2016 is a perpetual license, meaning you pay once and own that specific version forever, but it does not receive feature updates. Microsoft 365 is a subscription service that requires regular payments but always provides the latest features, security updates, and cloud storage.

How do I find my Microsoft Office confirmation ID?

The confirmation ID is not printed on a box or sent via email. It is generated by calling the Microsoft activation hotline provided in the Office Activation Wizard and providing your unique Installation ID to the automated system.

Why is my Office 2016 asking me to activate a Microsoft 365 subscription?

This usually happens if your computer came with a pre-installed trial of Microsoft 365. When you try to activate your Office 2016 key, the system gets confused. You may need to uninstall the Microsoft 365 apps from your computer's settings and then freshly install Office 2016 from your Microsoft account.
