Agent-callable Microsoft Outlook tools — read and search mail, send/reply/forward, organize messages and folders, manage calendar events, and manage contacts.

  • The user mentions Outlook
  • SKILL.md covers When to use this, Setup, Scripts and Disambiguation & refusals, plus 3 more sections
  • Runs TypeScript and JavaScript scripts from its folder; calls npm, npx and git; reaches graph.microsoft.com
  • Microsoft 365 mail/calendar/contacts

What it does

Microsoft Outlook is an agent skill from zapier/connectors, published by the product's own GitHub organization. Agent-callable Microsoft Outlook tools — read and search mail, send/reply/forward, organize messages and folders, manage calendar events, and manage contacts. Use when the user mentions Outlook, Microsoft 365 mail/calendar/contacts, or wants to send, read, search, or organize email, schedule events, or look up contacts — even if they don't name Outlook explicitly.

Its SKILL.md is about 4.6k tokens, which your agent loads only when the skill is triggered. The skill folder holds 92 other files, including scripts and reference files (for example `.claude-plugin/plugin.json`, `.mcp.json` and `CHANGELOG.md`). Compatibility notes: Run npm install --omit=dev in this directory, then node cli.js. The TypeScript source needs Node.js 22.18+; on older Node, run cli.js for build-it-yourself /…

It sits in Documents & Office, covering Cloud office suites. It works with Microsoft Outlook, Microsoft 365 and Zapier. The repository describes itself as: Connect your agent to the apps you already use - with or without Zapier.

When your agent uses it

  • The user mentions Outlook
  • Microsoft 365 mail/calendar/contacts
  • Schedule events
  • Look up contacts — even if they dont name Outlook explicitly

Example prompts

  • “/microsoft-outlook”

Requirements

  • Node.js
  • Compatibility (from SKILL.md): Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options.

What it can do on your machine

Read from SKILL.md and the folder at commit e48d26f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (TypeScript and JavaScript, from the files we listed), which the agent can run.

    Shell commands in SKILL.md call:

    • npm
    • npx
    • git

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • graph.microsoft.com

    Also links to:

    • learn.microsoft.com
    • agentskills.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Run `npm install --omit=dev` in this directory, then `node cli.js`. The TypeScript source needs Node.js 22.18+; on older Node, run `cli.js` for build-it-yourself / prebuilt / alternative-runtime options.

    From compatibility in the SKILL.md frontmatter.

Context cost

Microsoft Outlook loads about 4.6k tokens when it runs, and up to ~18k if it reads all its reference files. Until then it costs about 96 tokens; SKILL.md has 1,493 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~96
When it runs · the whole SKILL.md, loaded when a task matches
~4.6k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~18k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

SKILL.md

Its licence (Elastic-2.0) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,493 words (~4,617 tokens).

“Tools for a single user's Outlook mailbox against the Microsoft Graph API v1.0 (https://graph.microsoft.com/v1.0/): read and search mail, compose/send/reply/forward, organize messages (read state, flag, importance, categories, move, copy, delete), browse mail folders and attachments, manage calendar events, and manage personal…”
