Recently, I searched for the Org Explorer app in Microsoft 365 Copilot. It’s usually a good way to quickly find colleagues. The app was not available.
Then I found an old link referencing the Org Explorer app in Microsoft 365 Copilot: m365.cloud.microsoft/m365apps/1f8c20f5-d70f-4f8e-93e1-31d8fce0c8c9

So, the Org Explorer app is still available. With Microsoft, you never know if an app will disappear from one day to the next.
I then registered the m365.cloud.microsoft domain. I already updated my favorites to the new domain, copilot.cloud.microsoft.
And indeed, it seems Microsoft forgot to update the app. The Org Explorer app is restricted to the m365 subdomain and does not yet support the new Copilot domain.
Try the URL: https://copilot.cloud.microsoft/m365apps/1f8c20f5-d70f-4f8e-93e1-31d8fce0c8c9
The current result is an error. It’s also not available if the app is pinned.
Unable to resolve requested application.

The Edge DevTools reveal further issues with the app.

That’s why you cannot find the app. It is not ready for copilot.cloud.microsoft yet.
