Sigsync Signatures Add-in for Outlook
Sigsync Signatures Add-in for Outlook enables organizations to centrally manage and automatically insert email signatures when users compose, reply to, or forward emails in Outlook. Once deployed, the add-in ensures that the correct, up-to-date signature is applied automatically—removing the need for users to manually create or maintain signatures on their devices.
The add-in supports Outlook Desktop, Outlook on the Web (OWA), and Mobile devices (Androids, iOS), providing a consistent signature experience across all platforms. Signatures are synchronized in real time using user profile attributes, ensuring accuracy for contact details, disclaimers, branding, and dynamic content.
The Sigsync Add-in Pane within Outlook allows users to preview their signature and manually insert or reinsert it when required, offering flexibility while maintaining centralized administrative control.
Deployment of the Sigsync Outlook Add-in is performed through the Microsoft 365 Admin Center using Integrated Apps. Deployment changes are managed by Microsoft and may take up to 72 hours to propagate and become available to all assigned users. To deploy and manage the add-in, administrators must have Global Administrator or Exchange Administrator roles.
