Building and customizing solutions using Microsoft 365 Copilot APIs and tools
If you have an old deployment removing the OLD Microsoft.MicrosoftOfficeHub appx package, it's killing the copilot desktop app.
The new Microsoft 365 Copilot desktop app is literally the exact same background package as the original Office Hub. Microsoft did not build a brand-new application; they rebranded and updated the existing package container to shift focus toward their AI features.
Identical Package Architecture
- Same Package Name: Under the hood, the application still uses the exact same AppX identifier:
Microsoft.MicrosoftOfficeHub. - Same Store ID: Both versions share the identical Microsoft Store product identifier (
9WZDNCRD29V9). - Automatic Overwrites: If you have the old Office Hub or "Microsoft 365 (Office)" app installed, standard Windows updates automatically overwrite it and transform the shortcut into the new Copilot app. [1, 2]
