How can activate the product Microsoft office Professional Plus 2013 This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I purchased the office 365 Home on Feb, 2018. It was working fine. But when I come back from vacation for 4 weeks, trying to open outlook, excel, word, all these are showing Product Activation Failed.
Problem
Fired up one of my test machines this morning, and opened Outlook to see,
Error: Microsoft Outlook (Product Activation Failed)
Though if you open other applications you will get the same;
Error: Microsoft Word (Product Activation Failed)
Error: Microsoft Excel (Product Activation Failed)
etc.
Solution
I’m not sure why this happened, (perhaps I entered the wrong key when I installed it). But it’s simple to fix.
1. In this Example I’m using Outlook but select > File > Help > Change Product Key.
2. Enter a valid Office 2010 key > Continue > Follow the on-screen prompts.
3. When finished, restart Outlook and it will prompt you to activate, again follow the instructions.
4. When complete it should say “Thank You. You copy of Microsoft Office {version} is activated” > Restart your Office applications to remove the red warning bar.
