LiquidFiles OutlookPlugin for Windows

Overview

LiquidFiles Outlook Plugin is an add-on for Microsoft Outlook that streamlines the process of sending oversized attachments from the desktop mail client. It aims to simplify attachment handling so users can share large documents without having to manually upload files to separate services.

Key advantages

• Simplifies attachment management so large files can be shared directly from Outlook.
• Enables sending much larger attachments than standard email limits allow.
• Integrates with desktop Outlook and many Office 365 deployments (desktop clients), providing an in-app experience for users who work primarily in the classic Outlook interface.

Platform support and limitations

• The add-on is delivered as a desktop extension rather than a cloud-based Office 365 add-in, so it won’t appear in browser-based Outlook or certain cloud-only environments.
• It is not supported in Outlook on the Web (OWA) or the “New Outlook” for Windows.
• Check compatibility with your organization’s Outlook build before deployment, as support varies between classic desktop clients and newer/web-based clients.

Suggested alternative

• SHAREit (Free) — a popular, free tool for direct file transfers across devices; useful when you need quick, cross-platform sharing outside of email.
• Consider this or other standalone file-transfer utilities if you require web-based integration or need to work with the new Outlook interfaces that the LiquidFiles add-on doesn’t support.

When to choose each option

If you want an in-Outlook solution for sending large files from a classic desktop client, LiquidFiles is a practical choice. If your workflow depends on Outlook for the Web, the New Outlook for Windows, or purely cross-device transfers, explore standalone alternatives such as SHAREit.
