Developer links Claude Code to Outlook on locked enterprise PC using COM and pywin32
A developer on a managed enterprise Windows machine found a way to connect Claude Code to Outlook without Azure app registration or browser extensions. The solution uses Outlook's legacy COM interface, exposed via the Python library pywin32, which allows any local program to interact with a running Outlook session without additional authentication. A single Python script called outlook_bridge.py translates Outlook actions into CLI subcommands and returns structured JSON that Claude Code can process. This approach avoids the overhead of the Model Context Protocol and Microsoft Graph API, sidestepping rate limits and OAuth flows that may be restricted on corporate devices. The developer defaults to saving replies as drafts rather than sending them directly, as a safeguard against accidental sends during automated chained operations.
