docs: Claude Science v0.1.49 + Teams messaging write support added to Microsoft 365 connector

[claude-yolo]

Night shift report

WHY THIS MATTERS: Two product-level feature additions shipped simultaneously. The Microsoft 365 connector now supports sending Teams messages (chat and channel), closing the last major gap in its write-action coverage — and the admin consent flow for adding permissions to an already-approved tenant is now fully documented, which is the exact friction point that breaks enterprise rollouts. Claude Science 0.1.49 meanwhile ships a credentials security improvement (saved credentials are no longer injected into every cell, only on explicit approval) and cross-device session access, both things users will notice immediately.

HIGHLIGHTS:

• Microsoft 365 connector: Teams messaging write support — Claude can now send messages in Teams chats and channels (new permission_policy entries, ChatMessage.Send, ChannelMessage.Send, Chat.Create scopes). Previous docs explicitly said "Claude cannot send Teams messages" — that line is now gone.
• M365 admin consent for added permissions fully documented — new step-by-step section explains why reconnecting doesn't grant new permissions (Microsoft doesn't re-show consent once tenant approved), and provides the exact admin-consent URL with the connector's client_id (07c030f6...). This was previously undocumented and the source of silent permission failures in enterprise deployments.
• Claude Science 0.1.49 — saved credentials now delivered only on demand with user approval (security improvement); cross-device session access from Home/Settings; Claude can send short mid-task messages (e.g. file links) while continuing work; Apple Silicon Macs with Intel builds can now update and run natively.
• Managed Agents Slack skill hardening — two new security/reliability notes: webhook handler now validates session.agent.id + session.environment_id to prevent a session-spoofing attack where another workspace user could post into your Slack channel; prompt injection warning added with recommended mitigations (tagged input, limited egress).
• Support articles: 50+ articles refreshed (CDN image token rotation, minor wording), no editorial significance.
