Set-OutlookSignatures, the Benefactor Circle add-on and the Outlook add-in are now available in version 4.29.0. This update introduces critical security continuity measures, enhanced compliance documentation, and several internal robustness fixes to keep your deployments running smoothly.
🔗Code-Signing Certificate Update (Annual Rotation)
Thanks to a generous donation from our partner ExplicIT Consulting, our Enterprise Validated (EV) code-signing certificate has been renewed.
- Action Required: If your endpoint security software (such as AppLocker, Microsoft Defender, or CrowdStrike) is strictly locked to our previous certificate, please update your configuration rules to accept the new one.
- Future Changes: To comply with updated industry-wide Certificate Authority (CA) guidelines, this certificate will now be rotated annually.
- Better Appending: The update process now appends ExplicIT’s certificate instead of replacing existing ones, ensuring original certificates from Microsoft or the .NET Foundation remain fully intact.
🔗New Security Questionnaire & Resources
To streamline internal IT and compliance reviews, we have added a dedicated Security Questionnaire section to our documentation. It provides clear answers to standard security and data privacy questions.
Additionally, we’ve included links to our latest deep-dive articles:

🔗Key Robustness & Fixes
- Assembly Resolver Update: Resolved an issue where DLL files downloaded from the web with the "Mark of the Web" restriction could not be loaded.
- OutlookSignatureName priorization: Fixed the
OutlookSignatureNamebehavior in the INI configuration to prevent overwriting signature names already assigned to higher-priority mailboxes. - Dependency Upgrades: Bumped underlying libraries including MSAL.Net, libphonenumber-csharp, and msal-browser.
