You can get the Confirmation ID through telephone to activate Office :
- Open one Office app, such as Word.
- If it doesn’t ask for a product key right away, go to “File” and then “Account”.
- Under “Product Information”, look for “Activate Product”.
- Click on “I have a product key” and put yours in.
- When it asks how you want to activate, pick “I want to activate the software by telephone” instead of over the internet.
- After choosing phone activation, you’ll see your Installation ID. It’s long, so be ready to write it down.
- Look for the toll-free number in the activation window. Select the country or region you are calling from. It will then display a toll-free number that you can call. Most countries have a number with a free call at the expense of Microsoft.
- Follow the voice instructions on the call.
- Enter your Installation ID when asked.
- The system will check your ID and then give you a Confirmation ID. Please write it down.
- Click on the “Enter Confirmation ID” button and type the number they provided.
- That should complete the activation for you.
If the Telephone activation does not work, I suggest you activate Office via Internet or call Microsoft Support for assistance: error when activating Office
