Updated February 16, 2024: We have updated the rollout timeline below. Thank you for your patience.
We are making changes to the file open experience in Teams that will affect users in select scenarios. These changes are part of our ongoing security enhancements and optimizations to provide you with the best possible collaboration platform.
[When this will happen:]
Beginning in late February 2024 and completing by late March 2024, on classic Teams version >1.6.00.34970
[How this affects your organization:]
The following changes will take effect:
- All files in Shared channels will now open in browser instead of within Teams. This will ensure that you can access all the latest features and functionalities of the web app.
- OneNote notebooks pinned to channels/chats or the Notes tab within channels will continue to open within Teams. However, OneNote files when launched from any other surface in Teams will open in browser. This is a temporary situation for a few weeks until we integrate latest file open behavior into the OneNote Teams app, at which point you can go back to working with these files within the Teams environment.
- Some Word, Excel, and PowerPoint files that are pinned as tabs on chats/channels using the “Make this as tab” feature will render in read-only mode due to the legacy viewer powering the experience. Users will be asked to re-pin those documents as tabs to get an edit-ready experience powered by the latest viewer app for a more secure experience.
- For users on classic Teams version older than 1.6.00.34970, files in the above scenarios will open in read only mode.
[What you can do to prepare:]
- We recommend upgrading to new Teams or to 1.6.00.34970 and above versions of classic Teams.
- You may consider updating training and documentation as appropriate.
