Signature 365 for Microsoft Outlook

Signature 365 gives your company complete control over email signatures from one central admin portal. Design once, distribute automatically, and ensure every employee sends a consistent, professional signature across desktop, web, and mobile.

Who benefits:

• Marketing turns every email into a branding channel with dynamic banners that activate and expire on set dates.
• HR gets automatic signatures for new hires, pulled straight from Microsoft Entra ID (Azure AD), with instant deactivation when someone leaves.
• IT eliminates manual setup and helpdesk tickets through server-side, cloud-based distribution.
• Leadership gets a unified company image and a no-cost marketing channel that scales from 5 to 500+ employees.

Key features: centralized management, dynamic campaign banners, visual HTML editor with live preview, AI template assistant, automatic Entra ID synchronization, and REST API integration with your existing systems.

Works everywhere you send mail: Outlook Desktop (Windows & Mac), Outlook Web (OWA / M365), and Outlook Mobile (iOS & Android). Built on an ISO/IEC 27001-certified, GDPR-compliant platform as an official Microsoft 365 partner solution.

Background & Automated Features:

This add-in utilizes event-based triggers (LaunchEvents) to automate tasks in the background without requiring manual clicks:

On New Message / Compose automatically appends your company signature

On Message From Change automatically appends/updates your company signature

On New Appointment Compose automatically appends your company signature

Note: These event-based features run automatically in Outlook to streamline your workflow.
