Outlook Assistant
A comprehensive Microsoft Graph API wrapper that gives Claude direct access to your Outlook mailbox. Goes well beyond basic email reads with 22 consolidated tools covering inbox rules, delta sync for polling changes, forensic header analysis (DKIM, SPF, DMARC chains), conversation threading, and bulk exports to MBOX, EML, or Markdown. Includes dry-run previews and mail tips before sending, plus category management and Focused Inbox controls. Works with both personal Outlook.com and Microsoft 365 accounts, though KQL search and shared mailbox access require the latter. The delta sync is especially clever for building monitoring workflows without repeatedly fetching your entire inbox. If you're building email automation or need programmatic mailbox access from your AI assistant, this covers the full surface area.
