name: outlook description: >- Manage personal Microsoft 365 (Outlook.com/Hotmail/Live) email, calendar, and OneDrive via the m365-cli command-line tool. Requires: Node.js 18+ and m365-cli installed globally (npm install -g m365-cli), plus OAuth authentication (m365 login --account-type personal). Accesses sensitive data: emails, calendar events, OneDrive files, and contacts. Use when: (1) reading, sending, or searching emails, (2) managing calendar events (list, create, update, delete), (3) uploading/downloading OneDrive files, (4) searching users/people, (5) deleting or moving emails, (6) managing mail folders, (7) any task involving personal Outlook/Hotmail/Live account management from the terminal. Triggers: "check my email", "send an email", "schedule a meeting", "list my calendar", "upload to OneDrive", "download from OneDrive", "search mail", "what's on my calendar", "manage Outlook", "m365", "outlook", "delete email", "move email", "mail folders", "create folder", "organize email".

Outlook Skill (m365-cli)

Manage a personal Microsoft account (Outlook.com / Hotmail / Live) via the m365 CLI. Use --json for structured output suitable for AI agent consumption (most commands support it).

Prerequisites

• Node.js 18+
• m365-cli installed globally: npm install -g m365-cli
• Authenticated: m365 login --account-type personal

If not authenticated, run login first. The CLI uses Device Code Flow — follow the on-screen URL and code.

Key Conventions

• Use --json for programmatic output (most commands support it; trust/untrust do not).
• Personal accounts support: Mail (including delete, move, and folder management), Calendar, OneDrive, User search. Not SharePoint.
• Calendar datetime format: YYYY-MM-DDTHH:MM:SS (local) or YYYY-MM-DD (all-day).
• IDs: Email/event IDs are long opaque strings. Parse the id field from --json list/search output.
• Timezone: auto-detected. Override: export M365_TIMEZONE="Asia/Shanghai".

User Search

m365 user search "John" --top 5 --json    # Searches contacts and people

Common Patterns

Read and reply to email

m365 mail list --top 5 --json                    # 1. Find email
m365 mail read <id> --force --json               # 2. Read content
m365 mail send "sender@ex.com" "Re: Sub" "Reply" --json  # 3. Reply

Check calendar and schedule

m365 cal list --days 3 --json                    # 1. Check availability
m365 cal create "Meeting" -s "..." -e "..." --json  # 2. Book slot

Download email attachment

m365 mail attachments <msg-id> --json            # 1. List attachments
m365 mail download-attachment <msg-id> <att-id> ~/Downloads/ --json  # 2. Download

Delete and organize email

m365 mail list --top 10 --json                   # 1. Find email
m365 mail delete <id> --force --json              # 2a. Delete it, OR
m365 mail move <id> archive --json                # 2b. Move to archive

Manage mail folders

m365 mail folder list --json                      # 1. List all folders
m365 mail folder create "Projects" --json         # 2. Create custom folder
m365 mail move <id> <folder-id> --json            # 3. Move email into it

Trusted Senders (Security)

m365 mail read filters untrusted sender content (shows metadata only). Use --force to bypass. See references/commands.md for whitelist management commands.

Full Command Reference

See references/commands.md for every command, subcommand, flag, and default value.

Troubleshooting

• "Not authenticated": m365 login --account-type personal
• Token expired: Auto-refreshes. If fails, re-run login.
• SharePoint errors: Personal accounts don't support SharePoint.
• Wrong timezone: export M365_TIMEZONE="Your/Timezone"

Security & Privacy

This skill accesses personal email, calendar, files, and contacts — all sensitive PII.

• Never read, output, or log ~/.m365-cli/credentials.json — it contains OAuth tokens.
• Never include full email bodies or attachment contents in agent output unless the user explicitly requested that specific email.
• Summarize email content instead of echoing it verbatim when presenting results to the user.
• Credential refresh is automatic; never attempt to manually edit or parse the token file.
• When listing emails, prefer showing metadata (subject, sender, date) over full body content.
