With help from Copilot...

"I purchased Office Professional Plus 2016 through my employer about 10 years ago, paid for it personally, and still have the original product key. My computer crashed and I no longer have the installer. I'd like to know whether the license can be reinstalled and how to obtain the correct installation media."

    Hi Bruce Mol,

    Since you purchased Office Professional Plus 2016 through your employer but paid for it personally, the key point is whether the purchase was made through the former Microsoft Home Use Program, now called the Workplace Discount Program.

    Please start with Microsoft’s official Workplace Discount Program order-history page and enter the work email address that was used for the original purchase. Microsoft may send the product key and installation information to that address, so also check its junk or spam folder.

    If nothing is received, sign in to your personal Microsoft account and check Services & subscriptions to see whether Office 2016 was associated with that account.

    Because the previous computer failed, activation on the replacement computer may report that the activation limit has been reached. Whether the license can be moved depends on the license terms attached to that specific purchase. If the transfer is permitted, Office 2016 may require telephone activation. You can follow Microsoft’s official guidance for activating Office after reinstalling it or installing it on another device.

    Please avoid downloading an Office Professional Plus ISO from an unofficial website, since the installer must match the edition and licensing channel of your product key.

    Also be aware that Office 2016 has reached the end of support. It may still install and activate with a valid license, but it no longer receives security updates or technical fixes. Thank you so much for your understanding.

    Because Office Professional Plus 2016 was purchased personally through an employer, recover its installer and order details through the Microsoft Workplace Discount Program (formerly HUP) order-history process first. ^1^

    Reinstall a personal HUP/Workplace Discount Program copy

    1. Open the Workplace Discount Program Order History page linked from Microsoft’s reinstall article. ^1^
    2. Enter the work email address originally used for the purchase, even if a different personal Microsoft account is used today.
    3. Check that work mailbox and its junk folder:
      • If Microsoft sends an email containing the product key or order information, follow the installation instructions in that message.
      • Older Workplace Discount Program purchases can also expose the key on the Order Details page. ^2^
    4. If no email arrives, sign in to the Microsoft account → Services & subscriptions page using the personal Microsoft account that may have been associated with the purchase—not the work account. Look for Office Professional Plus 2016 and select Install. ^1^
    5. Run the downloaded installer, open Word or Excel, accept the license terms, and complete any Activation Wizard prompts.

    Do not download an Office Professional Plus ISO from an unofficial archive. The edition and licensing channel must match the key; the Workplace Discount Program order page or the associated Microsoft account is the supported source for this purchase.

    Can the license be used again?

    A product key and proof of purchase establish the purchase history, but they do not by themselves confirm that the license can be transferred to a different computer. Microsoft’s Office 2016 installation guidance describes a one-time-purchase copy as licensed for one installation. ^3^

    • Same repaired computer: reinstall using the recovered HUP media and activation information.
    • Replacement computer: install only if the recovered order/license terms permit it. Activation may require Microsoft to validate the license and prior failed computer.
    • Keep the original receipt, order number, and product key available. Do not post them publicly.

    If the original work mailbox no longer exists, the order-history email cannot be received, or the product is absent from every plausible Microsoft account, the available public guidance does not provide another installer-recovery method. Contact Microsoft Support and provide the purchase evidence for license validation.

    If this was actually an organization-managed volume license

    Use this branch only if the employer—not you personally—owned and deployed the license through volume licensing. In that case, Office Professional Plus may use MAK, KMS, or Active Directory-based activation, and the organization must provide matching installation media and activation. ^4^

    Contact the employer’s IT or licensing administrator. Authorized volume-licensing administrators can obtain downloads and keys from the Microsoft 365 admin center under:

    Billing → Your products → Volume licensing → View downloads and keys ^5^

    A personal HUP key should not be replaced with an employer’s MAK or KMS key.

    Security status

    Office 2016 reached end of support on October 14, 2025. It may continue to run, but Microsoft no longer provides security fixes, bug fixes, or normal phone/chat technical support; upgrading to a supported Office release is recommended. ^6^
