Summary:
Microsoft Teams will retire the "Code snippets" feature for chats and channels from early to mid-June 2025. Users should transition to "code blocks," which will soon include line numbers and mobile device support. No admin action is required, but users should be informed. Existing code snippets will remain accessible.

Details:
Updated June 4, 2025: We have updated the timeline below. Thank you for your patience.
We will retire the code snippets feature for chats and channels from Microsoft Teams starting early June 2025 (previously May 30) and ending mid-June 2025 (previously June 16). We made this decision to streamline our development efforts and enhance the overall user experience by focusing on code blocks, which are faster and more efficient, allowing users (mainly developers) to create, edit, and share code directly in the compose box without needing a title. Code blocks offer almost all the features of code snippets, except for line numbers. We will be adding line numbers to code blocks in the coming months. Also, code blocks will soon be viewable on mobile devices, ensuring that users can access and collaborate on code from anywhere.
This message applies to Teams for Windows desktop. Teams for Mac desktop, and Teams for the web.

Code block example:

Users will no longer be able to create code snippets after the feature retires, but all previously sent code snippets will remain accessible in Teams. Users will not be able to create new code snippets after May 30, 2025.
This change will happen automatically by the specified date. No admin action is required. Please notify your users about this change, update relevant documentation as appropriate, and share the code blocks alternative.

explanation for non-techies**

Microsoft Teams is making a change to how users can share code within chats and channels. Imagine you have a favorite tool or gadget that you've used for a long time, like a trusty old calculator. It's done the job well, but now there's a new model that’s sleeker, faster, and can do more things. That's what's happening with the "code snippets" feature in Teams.

The "code snippets" feature is being retired, which means it will no longer be available for creating new snippets after mid-June 2025. However, any code snippets that were created before this change will still be accessible. The new tool replacing it is called "code blocks." Think of code blocks as the upgraded version of your calculator. It’s designed to be more efficient and user-friendly, allowing developers to write and share code directly in the chat without needing to add a title.

Code blocks are like a notebook that lets you jot down ideas quickly and share them easily. They are almost identical to code snippets but will soon include line numbers, making it easier to reference specific parts of the code. Additionally, code blocks will be accessible on mobile devices, so you can review and collaborate on code from anywhere, just like being able to use your calculator on the go.

For those who use Microsoft Teams on Windows, Mac, or the web, this change will happen automatically, so there's no need for any administrative action. However, it's important to inform users about this transition and update any relevant documentation. This way, everyone can smoothly switch to using code blocks and continue their work without interruption.

For more information on how to use code blocks or to understand the transition better, Microsoft Support provides detailed guides and resources.
