What you give up

- △No Loop components for collaborative editing within chat
- △No Power Automate integration for workflow triggers from messages
Switching Cost
Teams locks you in through the Microsoft 365 ecosystem, not the chat itself. Messages can be exported, but the SharePoint file sharing, OneDrive integration, Power Automate workflows, and Planner task boards are deeply wired into the Microsoft stack. Orgs using Teams as just a chat app can switch in a day. Orgs running their entire workflow through Microsoft 365 (Teams + SharePoint + Power Automate + Planner) should budget weeks to untangle the dependencies. The hidden cost is the meeting infrastructure: if your entire company schedules through Outlook and meets through Teams, changing one means changing both.

Building Blocks
Microsoft Teams is a platform. It bundles multiple capabilities into one subscription. These tools each cover one piece. Teams often assemble 2–3 of them instead of paying for the full suite.
