(Updated) Changes to the Website tab in the new Teams client.

Updated March 15, 2024: We have updated the rollout timeline below. Thank you for your patience.

Starting mid-July 2024 (previously April), Microsoft Teams will be retiring the ability to load websites inside the new Teams client when using the Website tab. These website links will open in a new browser tab instead. This is to better align with emerging best practices in web security and privacy while also improving the reliability of websites opened through this feature.

Please note that EDU tenants will not be impacted as we are still researching options on how to best provide a non-disruptive way to access websites for students and educators at a later date.

When this will happen:

We will begin rolling out this change in mid-July 2024 (previously early April).

How this will affect your organization:

Users will no longer be able to view websites inside the new Teams desktop and web clients when using the Website tab and will instead be opened in a new browser tab. Existing Website tabs will also be opened in a new browser tab.

The Teams mobile apps will not be impacted.

The following is the answer I got back from Microsoft:

The Website tab is not a supported mechanism for integrating content into Teams. The Website tab has always been a best effort mechanism and we cannot guarantee that the content embedded in it will work as expected. If the content doesn't work, then customers should click on the "Open in browser" button in the warning header to launch the pinned URL in their default browser where it should work as expected: From a technical perspective, the Electron webview that we used to embed websites into the Classic Teams Client has been deprecated and we have switched to using a vanilla iframe in the New Teams Client. That means a number of sites that worked in the Classic Teams Client will no longer work in the New Teams Client. Customers should use dedicated apps from the Store to embed the content where available or load the sites in their browser if no app is available.

Yep, same old nonsense here. Works in old Teams, not in new.

Thanks for this thread, I thought I was going crazy. I've now tried everything - Trusted Sites via GPO, Trusted Sites via OMA-URI... Everything possible and I can't get the flag off.

I hope that Microsoft will adjust this, we have over 6000 users who are, well, annoyed by it. A return to the old team as a solution approach is actually not acceptable.

Seems to only work if you have the Old Teams version running. I was on the new version, and it wouldn't work I switched back to the old version and it works.
