What are the steps to publish an application solely for Microsoft Teams rather than for Microsoft 365?

Question

What are the steps to publish an application specifically for Microsoft Teams rather than for Microsoft 365? Is there a way in the Partner Center to select "Microsoft Teams" as the sole supported platform? Or is it necessary to list the supported clients in the manifest? Please guide me

Answer 1

The app manifest (previously called Teams app manifest) describes how your app integrates into the Microsoft Teams product. Use manifestVersion 1.13 to enable Teams app support in Outlook and Microsoft 365 app; use 1.12 (or earlier) for Teams-only apps.

The following table lists TeamsJS version and app manifest versions as per different app scenarios:

App type	TeamsJS version	App manifest version	Next steps
Teams apps extended across Outlook and Microsoft 365	TeamsJS v.2.19.0 or later	v.1.13 or later	Extend a Teams app to run across Microsoft 365 or Create a new Microsoft 365 app
Existing Teams-only apps	Update to TeamsJS v.2.19.0 when possible (v.1.12 is still supported*)	1.12	Understand TeamsJS backwards compatibility and Update to TeamsJS v.2.0
New Teams-only apps	TeamsJS v.2.19.0 or later	1.12	Create a new Teams app using Teams Toolkit

Regarding the Partner Center, there isn't a specific option to select "Microsoft Teams" as the sole supported platform.
