Microsoft Teams has become the backbone of modern collaboration, enabling organizations to communicate, share ideas, and work together seamlessly. In its latest update, Microsoft is taking collaboration to the next level by introducing a feature that allows users to share files and Loop components with external participants in chat. This enhancement, rolling out in November 2026 across Desktop, Mac, and Web platforms, is designed to make working with clients, partners, and vendors easier than ever.
Until now, sharing files in Teams chats was primarily an internal affair. External user often faced limitations, requiring additional steps such as email attachments or separate file-sharing platforms. With this update, Microsoft Teams removes those barriers. You can now share files and Loop components directly in:
- 1:1 Chats
- Group Chats
- Meeting Chats
This means external collaborators can access shared content instantly, without jumping through hoops or dealing with permission issues.
How It Works
When you send a file or a Loop component in a chat that includes external participants:
- The file is automatically provisioned to all users in the chat.
- You have the option to change permissions before or after sending.
- External users can view, edit, and collaborate in real-time, just like internal team members.
This feature is a game-changer for organizations that frequently work with external stakeholders. It eliminates friction in collaboration, reduces dependency on email attachments, and ensures everyone stays aligned in one secure environment.
Collaboration with external stakeholders is a critical part of business operations. Whether you’re working with a client on a proposal, coordinating with a vendor, or brainstorming with a partner, seamless communication is key. This update eliminates friction by:
- Reducing dependency on email attachments
- Centralizing collaboration within Teams
- Improving productivity and decision-making
By enabling external users to participate fully in chats and file sharing, Microsoft Teams strengthens its position as the ultimate hub for teamwork.
Security and Control
Microsoft understands that external sharing must be secure. This feature comes with robust controls:

What Are Loop Components?
Loop components are interactive, portable pieces of content that can be shared across Microsoft 365 apps. They allow teams to brainstorm, plan, and collaborate dynamically without leaving the chat interface. Examples include:
- Task lists
