How to activate Office 2019 Professional

Question

Have uninstalled Office 2019 on old computer and all forms of Office on new computer.

Can't activate Office 2019 on new computer.

Answer 1

You can try phone activation. Try calling the number for your region from the article at https://support.microsoft.com/en-us/office/-telephone-activation-is-no-longer-supported-for-your-product-error-when-activating-office-9b016cd2-0811-4cb3-b896-5a6a13177713 .

Note that if you purchased Office, years ago, as part of what was previously called the HUP (Home Use Program), see https://www.microsoft.com/en-us/workplace-discount-program/order-history .

Hi @Edita N,  

Office 2019 uses a volume license when it is sold to large organizations through Volume Licensing agreements. This version cannot be activated using a personal Microsoft account, and it does not appear under the normal “My Account” page the way consumer licenses do.  

 Because of this, if your copy of Office 2019 is a volume license, it must be activated using your organization’s activation method, such as a KMS server or a MAK key. For your reference how to activate Office 2019, kindly follow these following steps: Deploy Office 2019 (for IT Pros) - Office | Microsoft Learn. 

To help determine the next step, could you let me know where you originally purchased your Office 2019 license? If it was purchased through an online retailer, there is a possibility that the license may not be a genuine retail product key.
