manifest 1.25

The manifest 1.25 tag covers Microsoft Teams app distribution guidance tied to a July 2026 submission requirement. The available discussion focuses on new Teams Store submissions for channel-enabled apps and clarifies that the rule does not automatically apply to every internally deployed Teams app. Tenant-only custom apps and personal-scope message extensions follow separate distribution paths, so administrators need to identify an app’s scope and deployment route before planning repackaging. This tag is useful for tracking Microsoft’s manifest requirements, Store submission decisions, and the distinction between Marketplace apps and tenant-specific ZIP packages.
