Because Copilot plug-in capabilities vary by app, you should consult Microsoft developers to verify specific manifest requirements and cross-application controls.
Custom Microsoft 365 Copilot plug-ins do not universally share the exact same feature sets across all apps out-of-the-box. Individual product controls and messaging extension manifests dictate where and how a plug-in operates in Teams, Word, Excel, and others.
Open your web browser and go to the official Microsoft Q&A website, then log in with your Microsoft developer credentials.
Search for and navigate to the 'Office Development' section, which handles queries related to Microsoft 365 extensibility and Copilot plug-ins.
Create a new thread detailing your specific manifest requirements. Be sure to mention the exact Microsoft applications (e.g., Excel, Outlook, Loop) you are targeting.
Include relevant tags such as 'Copilot' and 'Microsoft 365 extensibility' before submitting so Microsoft engineers and developers can quickly locate and address your query.

Not always automatically. While some Microsoft 365 Copilot plug-ins support cross-app functionality, their availability and specific features depend heavily on the plug-in's manifest and developer configurations tailored for each app.
Why isn't my Copilot plug-in showing up in Excel?
Excel may require specific product enablement or manifest support that differs from apps like Teams or Outlook. You should verify your extension manifest against Microsoft's latest development guidelines.
Where can I find the manifest requirements for Microsoft 365 Copilot?
Detailed manifest requirements and development documentation can be found on the Microsoft Learn platform and the Office Development section of the Microsoft Q&A website.
