This one needs environment variables set before it will start: OUTLOOK_ACCESS_TOKEN (Pre-obtained Outlook bearer token. Overrides the browser bridge. Power users / CI only; tokens last about 25 hours.), OUTLOOK_DISABLE_FETCHPROXY (Set to '1' to disable browser capture, requiring OUTLOOK_ACCESS_TOKEN.), OUTLOOK_API_BASE (Override the Outlook REST base URL. Defaults to https://outlook.office.com/api/v2.0.), OUTLOOK_WS_PORT (fetchproxy concentrator port used for token capture. Defaults to 37149, the fleet-wide shared port.), OUTLOOK_CAPTURE_TIMEOUT (Seconds to wait for the Outlook tab to make a request we can read a token from. Defaults to 30.), OUTLOOK_TOKEN_CACHE (Set to 'false' to stop caching the captured token between runs. Defaults to true.), OUTLOOK_TOKEN_FILE (Path to the cached token file. Defaults to ~/.office-outlook-mcp/token.json.). The author declared them in the registry entry; get the values from the project itself.
