1] Use the correct Office 365 activation key

If you are facing this problem in many instances, you might be using an illegal version of Microsoft Office or the wrong key. Either you already know this or have no idea. But no matter the situation, we urge you to get yourself a legal copy of the software.

Doing so not only disables the error but also ensures you are safe from potential viruses and malware that could infect your Windows 10 computer.

Moreover, make sure that the type of product key you are using is meant for this particular version of Office that you are installing. Check whether you have a retail edition or a volume license edition

2] Make use of the Office Licensing Diagnostic Tool

Those who are having problems with activating their version of Microsoft Office 365 would make a lot of sense to take advantage of the Office Licensing Diagnostic Tool that is freely available for download.

Visit the official website, download it, then install the program on your computer. From there, follow the instructions to activate your version of Microsoft Office once and for all.

3] Check for multiple versions of Office installed

It is possible for activation to fail if you have multiple versions of Office already installed on your computer. To figure this out, please open the Control Panel by clicking on the Windows key, then type Control Panel. From the search results, select Control Panel, then navigate directly to Program and Features.

If you come across several versions of Office, then right-click on the ones you do not want, and select Uninstall.
