Designed for users of Outlook Classic, the Unicli VSTO Add-in provides the same powerful features as the standard Microsoft AppSource add-in while running locally for faster performance and enhanced compatibility. Unlike AppSource add-ins that rely on Microsoft 365 and Exchange-based environments, the VSTO version supports any IMAP email provider, making it ideal for organizations with non-Exchange email services. The add-in is free to download, however an active Unicli account and subscription are required to use the service. Learn more at Unicli for Outlook.
