| description | The first Outlook calendar CLI built for AI agents on personal Microsoft 365 accounts — with offline conflict... Trigger phrases: `what's on my calendar today`, `find me an hour next week`, `do I have any conflicts`, `what meetings haven't I responded to`, `prep me for my next meeting`, `schedule a meeting on my Outlook calendar`, `use outlook-calendar`, `run outlook-calendar`. | |||||||

This skill drives the outlook-calendar-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:
- Install via the Printing Press installer. It defaults binaries to
$HOME/.local/binon macOS/Linux and%LOCALAPPDATA%\Programs\PrintingPress\binon Windows:npx -y @mvanhorn/printing-press-library install outlook-calendar --cli-only
- Verify:
outlook-calendar-pp-cli --version - Ensure the reported install directory is on
$PATHfor the agent/runtime that will invoke this skill.
If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.4 or newer):
go install github.com/mvanhorn/printing-press-library/library/productivity/outlook-calendar/cmd/outlook-calendar-pp-cli@latestIf --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.
Reach for outlook-calendar-pp-cli when an agent needs to read or write a personal Microsoft 365 calendar non-interactively. It is the right choice for daily-brief, schedule-this-meeting, find-me-time, what-changed-this-week, and prep-me-for-my-next-meeting tasks. Prefer it over hitting Microsoft Graph directly when you want offline-shaped queries (conflicts, free-time math, recurring drift) that the Graph endpoints don't expose as single calls.
These capabilities aren't available in any other tool for this API.
-
conflicts— Find overlapping events across all your Outlook calendars in one pass — the double-bookings Outlook's own UI never shows.When the agent needs to know whether a proposed time blocks the user, this is the source of truth across every calendar the user owns.
outlook-calendar-pp-cli conflicts --from today --to +7d --json --select pair_id,a.subject,b.subject,overlap_minutes
-
freetime— Compute N-minute gaps in your working hours over the next K days, honoring all calendars and optional OOF/tentative exclusion.When the agent needs to propose a meeting time, this gives a deterministic answer that respects the user's actual working hours.
outlook-calendar-pp-cli freetime --duration 60m --within 'Mon-Fri 9-17' --next 7d --exclude-oof --json -
review— Diff against the last delta-sync snapshot: what was added, rescheduled, cancelled, or had its RSVP change.Lets the agent answer "what changed since I last looked?" without scanning the whole week.
outlook-calendar-pp-cli review --since last-sync --json
-
pending— List events whose RSVP is still pending and whose start time is in the future, ordered by start.Agent task: "what invites do I still need to answer?" — answered in one query.
outlook-calendar-pp-cli pending --json
-
recurring-drift— For each recurring-series master, list instances whose start/end/subject/location diverged from the master pattern.Catches the silent organizer-side reschedules that cause people to join Teams calls at the wrong hour.
outlook-calendar-pp-cli recurring-drift --json
-
with— How often have I met with this person, and when did I see them last? Counts and recent N events from local store.Agent task: "how often do I meet with X?" without reading the whole calendar.
outlook-calendar-pp-cli with alice@example.com --since 90d --json
-
tz-audit— Surface events whose start time-zone differs from the calendar's default or from their own end-time TZ — likely-broken displays on other devices.Agent task: "are any of my events about to render at the wrong hour for someone?" — yes/no with the offenders.
outlook-calendar-pp-cli tz-audit --json
-
prep— For upcoming events in the next N hours, return a dossier: subject, location, attendee emails, organizer, body excerpt, attachments list, recurrence/online-meeting flags.Single tool call that gives an agent everything needed to brief the user on what's coming up.

When you know what you want to do but not which command does it, ask the CLI directly:
outlook-calendar-pp-cli which "<capability in your own words>"which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.
outlook-calendar-pp-cli prep --next 24h --json --select subject,start,end,location,attendeesAgent-friendly daily snapshot with all the fields a briefing needs and nothing else.
outlook-calendar-pp-cli freetime --duration 60m --within 'Mon-Fri 9-17' --next 7d --exclude-oof --jsonReturns gap windows in working hours, OOF excluded — pipe to jq '.[0]' for the first opening.
outlook-calendar-pp-cli review --since 'Mon 09:00' --jsonDiff buckets (added/rescheduled/cancelled/rsvp-changed) that surface organizer-side reschedules.
outlook-calendar-pp-cli pending --json --select subject,start,organizer.emailAll future events whose RSVP is still pending — narrow output via --select so the agent only sees the fields it needs.
outlook-calendar-pp-cli conflicts --from today --to +14d --json --select pair.a.subject,pair.b.subject,overlap_minutes,calendar.a,calendar.bAgents on multi-calendar users (consultant + personal) hit conflicts first to know what's actually colliding; dotted --select keeps the payload tiny.
Authentication uses OAuth 2.0 device-code flow against https://login.microsoftonline.com/common. Run outlook-calendar-pp-cli auth login --device-code once; visit the displayed URL on any device, enter the code, and you're done. Tokens are cached at ~/.config/outlook-calendar-pp-cli/config.toml (mode 0600). The CLI auto-refreshes the access token on expiry using the stored refresh token, so subsequent commands run non-interactively. The default client id is the Microsoft-published Graph PowerShell client (works with personal Microsoft accounts out of the box); pass --client-id to use your own Azure app registration. Personal Microsoft accounts (Outlook.com, Hotmail, Live, MSA) are first-class and tested.
Run outlook-calendar-pp-cli doctor to verify setup.
Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.
-
Pipeable — JSON on stdout, errors on stderr
-
Filterable —
--selectkeeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:outlook-calendar-pp-cli attachments list mock-value --agent --select id,name,status
-
Previewable —
--dry-runshows the request without sending -
Offline-friendly — sync/search commands can use the local SQLite store when available
-
Non-interactive — never prompts, every input is a flag
-
Explicit retries — use
--idempotentonly when an already-existing create should count as success, and--ignore-missingonly when a missing delete target should count as success
Commands that read from the local store or the API wrap output in a provenance envelope:
{
"meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
"results": <data>
}Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.
When you (or the agent) notice something off about this CLI, record it:
outlook-calendar-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
outlook-calendar-pp-cli feedback --stdin < notes.txt
outlook-calendar-pp-cli feedback list --json --limit 10
Entries are stored locally at ~/.outlook-calendar-pp-cli/feedback.jsonl. They are never POSTed unless OUTLOOK_CALENDAR_FEEDBACK_ENDPOINT is set AND either --send is passed or OUTLOOK_CALENDAR_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.
Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.
Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:
| Sink | Effect |
|---|---|
stdout |
Default; write to stdout only |
file:<path> |
Atomically write output to <path> (tmp + rename) |
webhook:<url> |
POST the output body to the URL (application/json or application/x-ndjson when --compact) |
Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.
A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.
outlook-calendar-pp-cli profile save briefing --json
outlook-calendar-pp-cli --profile briefing attachments list mock-value
outlook-calendar-pp-cli profile list --json
outlook-calendar-pp-cli profile show briefing
outlook-calendar-pp-cli profile delete briefing --yes
Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.
