Understanding the Add-in Certificate Verification Process
Our application provides add-ins for Word, Outlook, and Excel to enhance productivity and streamline workflow. At times, you may encounter warnings related to these add-ins if their certificates are not recognized as trusted on your device. To mitigate this, we offer a “Verify Add-in Certificate State” tool that ensures these certificates are properly verified and trusted.What does the “Verify Add-in Certificate State” button do?

1
Certificate Check
Each add-in’s certificate is reviewed to verify its presence in your Trusted Publishers store. This store serves as an approved list, allowing Office to recognize trusted add-ins without security warnings.
2
Prompt to Add Missing Certificates
If any certificate is missing, a prompt will appear, asking if you’d like to add it. Adding the certificate ensures the add-in is recognized as a trusted source, enhancing security and performance.
3
Log Collection for Troubleshooting
If the verification process encounters an error (e.g., a certificate can’t be verified or added), you will be prompted to send logs for analysis. The application will gather relevant logs, draft an email with the logs attached, which you can review before sending to our support team.
Why Certificates Matter for Add-ins
Microsoft Office requires all add-ins to be signed by trusted publishers to protect your data and environment from malicious code. By ensuring that each add-in’s certificate is verified and stored in the Trusted Publishers list, our application provides:- Security: Only verified add-ins run within your Office applications.
- Reliability: Add-ins from trusted publishers perform better and avoid potential security blocks by Office.
Common Reasons for Missing Certificates
Certificates may be missing from your Trusted Publishers store due to:- System Changes: Updates or changes to your system can sometimes reset the Trusted Publishers list.
- New Installations: For fresh installs, certificates might not yet be added to your system’s trusted stores.
- Office Security Policies: Strict security settings may prevent automatic certificate recognition.
