Claude's Microsoft 365 Connector Gains Write Access — Draft/Send Email, Manage Calendar, Edit Files

Anthropic (Releasebot)·low signal

Anthropic's release notes report the Claude Microsoft 365 connector now has write capabilities: it can draft and send email, create and manage calendar events, and create or update files in OneDrive and SharePoint. This moves the connector from read-only retrieval to taking actions inside a user's workplace stack — raising both productivity and the prompt-injection/authorization stakes highlighted by this week's GitLost disclosure.
