Estratos

Copilot Cowork

Microsoft 365 Copilot Cowork connects to Estratos through the Estratos Memory plugin, installed from the Microsoft 365 plugin marketplace.

Install the plugin

  1. In Copilot Cowork, open a conversation and select Browse plugins.
  2. Add the Estratos marketplace source:
   https://estratos.ai/plugins
  1. Select Add to Cowork, then enable it in Sources & Skills.

Copy the exact marketplace URL for your deployment from the Copilot Cowork card on Connect › Configure agents.

Approve the connection

Sign in to Estratos when prompted. The consent screen opens in your browser; pick the workspace to connect and click Allow. Cowork receives a token scoped to that workspace.

What installs

The plugin installs the memory connector plus the same skills, from the Microsoft 365 marketplace.

Rollout

Your Microsoft 365 admin can auto-deploy the plugin to everyone — each person signs in once when prompted. Each member's agent acts with that member's role.

Copilot Cowork support is a frontier preview. Steps may shift as the Microsoft 365 marketplace evolves; the Configure agents card always shows the current flow.

If it doesn't connect

See troubleshooting for reconnecting, token expiry, and testing your connection. For protocol-level details, see the MCP reference.
