Hello SandraKorres,
You might need to enable the pen with each application where you found out that ink tools is grayed out. Before we proceed, we would like to know if the pen worked before with Word, Excel and PowerPoint?
In the meantime, you can try to launch Office in safe mode and check if the same issue occurs. Since the pen is not working on multiple Office applications, we would suggest that you repair it through the Control Panel. This will help us diagnose what causes the issue and find an automatic fix or provide you a troubleshooting steps that can help resolve the issue. You may check this link for the steps that you can perform in repairing the Office program.
We are looking forward to your response.
