Solution 1Recommended

Check HUP eligibility and contact Microsoft Support

Use this approach to find out whether the retired user's HUP license remains eligible and whether Microsoft can help locate the purchase.

Home Use Program eligibility is tied to a participating employer, and the user may no longer be eligible after leaving the company. Microsoft Support can clarify the terms that apply to the original purchase.

1
Review HUP eligibility

Visit Microsoft's Home Use Program support pages and review the eligibility information for purchases made through an employer.

2
Check your Microsoft account

Sign in at account.microsoft.com and open Services & subscriptions to see whether the Office purchase appears. An older HUP purchase may not be listed there.

3
Contact Microsoft Support

Go to support.microsoft.com/contactus and explain that Office Professional Plus 2016 was purchased through HUP, the employer email is no longer accessible, and the product key is missing. Provide any purchase details you have.

Key recovery is not guaranteed: The backup DVD provides installation media but does not by itself establish activation eligibility. Support will determine what assistance is available.

Frequently Asked Questions

Can I activate Office 2016 using only the HUP backup DVD?

The DVD supplies the installation files, but activation also requires a valid license and the applicable activation credentials. Contact Microsoft Support if the product key is missing.

Can I still use my HUP license after retiring?

HUP eligibility is tied to a participating employer, so you may no longer be eligible after leaving. Review Microsoft's HUP information and ask Microsoft Support about the terms of your purchase.

Where can I look for my original Office purchase?

Check any saved receipts or order confirmations and sign in at account.microsoft.com to review Services & subscriptions. Older HUP purchases may not appear there.

Can WPS Office activate my Microsoft HUP copy?

No. WPS Office is a separate office suite and cannot activate Microsoft Office or recover its product key. It can open and edit many existing Office files instead.
