We currently offer two add-in versions: Showpad for Outlook 365 and Legacy Showpad for Outlook. Note: Showpad for Outlook 365 is the latest and highly recommended version.

Easier to distribute for admins with centralized deployment, automatic updates, and minimal seller action required. Available on Mac, Windows, and in the browser.
