used repair function to resolve some office product issues and lost the product key software

Hi Adam Colston,

If Office was previously activated, there may still be ways to recover your license information even if the original product key and packaging are no longer available. Based on your description, the repair process was used to address program issues, and you're now trying to restore your Office activation details.

Please try these quick checks:

1, Check your Microsoft account

• Sign in to your Microsoft account.
• Review Services & Subscriptions to see whether your Office product is associated with the account.

2, Check Office activation status

• Open Word or another Office app.
• Go to File > Account and review the activation information shown there.

3, Look for purchase records

• Search your email for an Office purchase confirmation.
• If the product was purchased from a retailer, check for any available purchase history or receipt.

4, If the key cannot be located

• Contact Microsoft Support and provide any proof of purchase you may have.
• The support team may be able to review available activation options for your specific Office edition.

Please note that this is a user-to-user support forum. Moderators, contributors including external Microsoft employees cannot directly intervene in Microsoft product features or access back-end systems. Our role is limited to providing technical guidance on reported issues, requests, or ideas.

If you can share which Office version you have (for example, Office 2016, Office 2019, Office 2021, or Microsoft 365), the community may be able to suggest more targeted guidance.
