Outlook Email

Read, search, and manage emails via Microsoft Graph API.

Sending Emails — Draft Mode

The Graph API token lacks Mail.Send scope (your organization's Azure AD policy), so sending is done via draft creation:

  • outlook_send.py creates a draft in Drafts folder — user clicks Send in Outlook
  • outlook_reply.py creates a reply/forward draft — user clicks Send in Outlook
  • The draft's webLink opens directly in Outlook Web for quick sending

Setup (run FIRST — every time, before any operation)

You MUST complete this setup before running any script. Do NOT skip this step.

sig status ms-graph 2>&1

Check the JSON output fields configured and valid:

  • configured: false → run Provider Setup below. Do NOT proceed without completing it.
  • valid: false (but configured: true) → run sig login ms-graph, then re-check.
  • valid: true → detect proxy (see below), then execute the user's request.

Provider Setup

  1. Read <SKILL_DIR>/references/provider-config.yaml
  2. Append the provider block to ~/.sig/config.yaml under providers:
  3. Ask the user: "Do you need a proxy to access this site?" — if yes, add networkProxy: <url> under the provider in config.yaml
  4. Run sig login ms-graph (with --network-proxy <url> if proxy was specified)
  5. Verify: run sig status ms-graph again — must show valid: true before proceeding

Proxy Detection (after provider is valid)

grep -A15 "^\s*ms-graph:" ~/.sig/config.yaml | grep networkProxy | awk '{print $2}'

If this outputs a URL, prefix ALL python3 commands with HTTPS_PROXY=<url> HTTP_PROXY=<url>. If using socks5, convert to socks5h for python (e.g. socks5://... → socks5h://...). If empty, no proxy needed.

Running Scripts

All scripts require setup to be completed first (see above).

Safety

Always show the user the draft (recipients, subject, body preview) and get explicit confirmation before calling outlook_send.py, outlook_reply.py, or outlook_manage.py --action delete.

KQL Search Syntax

Use KQL (Keyword Query Language) with outlook_search.py:

"quarterly report"                # Subject, body, or attachment name
from:jane.doe@example.com        # From a specific sender
to:john@example.com              # Sent to someone
subject:"weekly standup"          # In subject line
hasattachment:true                # Has attachments
received>=2026-04-01              # Received after date
from:jane subject:report          # Combined filters

Note: $orderby is not supported with $search — results are returned by relevance.

Key Concepts

Folder names — Use well-known names (Inbox, SentItems, Drafts, DeletedItems, Archive, JunkEmail) or folder IDs from outlook_folders.py.

Message IDs — Long opaque strings (e.g., AAMkAD...). Get from outlook_messages.py or outlook_search.py, then use with outlook_read.py, outlook_reply.py, outlook_manage.py, outlook_attachments.py.

Conversation threading — Each message has a conversationId. To see a full email thread: read one message, note its conversationId, then search/filter for other messages in that conversation.

HTML bodies — outlook_read.py converts HTML to plain text by default. Use --format html to get the raw HTML.

Time parameters — Accept both YYYY-MM-DD and full ISO 8601 (2026-04-13T09:00:00Z).

Error Handling

Error Cause Fix
401 Unauthorized Token expired Auto-run sig login (no user prompt needed), retry
403 Forbidden Insufficient permissions Check Graph API permissions (Mail.Read, Mail.Send)
404 Not found Invalid message/folder ID Verify ID from a list or search
429 Too Many Requests Rate limited Wait and retry
MISSING_ARGS Required arguments missing Check script --help
