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.
