# Outlook Skill

Access Outlook/Hotmail email and calendar via Microsoft Graph API using OAuth2.

## Quick Setup (Automated)

```bash
# Requires: Azure CLI, jq
./scripts/outlook-setup.sh
```

The setup script will:
1. Log you into Azure (device code flow)
2. Create an App Registration automatically
3. Configure API permissions (Mail.ReadWrite, Mail.Send, Calendars.ReadWrite)
4. Guide you through authorization
5. Save credentials (including tenant context) to `~/.outlook-mcp/`

## Manual Setup

See `references/setup.md` for step-by-step manual configuration via Azure Portal.

## Usage

### Token Management
```bash
./scripts/outlook-token.sh refresh  # Refresh expired token
./scripts/outlook-token.sh test     # Test connection
./scripts/outlook-token.sh get      # Print access token
```

### Reading Emails
```bash
./scripts/outlook-mail.sh inbox [count]           # List latest emails (default: 10)

./scripts/outlook-mail.sh search "query" [count]  # Search emails
./scripts/outlook-mail.sh from <email> [count]    # List emails from sender

./scripts/outlook-mail.sh bulk-delete <id1> <id2>... # Delete multiple messages
```

### Folders & Stats
```bash
./scripts/outlook-mail.sh folders                 # List mail folders

## Calendar

### Viewing Events
```bash
./scripts/outlook-calendar.sh events [count]      # List upcoming events
./scripts/outlook-calendar.sh today               # Today's events
./scripts/outlook-calendar.sh week                # This week's events

./scripts/outlook-calendar.sh quick <subject> [time]                  # Quick 1-hour event
```

### Managing Events
```bash
./scripts/outlook-calendar.sh update <id> <field> <value>  # Update (subject/location/start/end)
./scripts/outlook-calendar.sh delete <id>                  # Delete event
```

Date format: `YYYY-MM-DDTHH:MM` (e.g., `2026-01-26T10:00`)

### Example Output

```bash
$ ./scripts/outlook-mail.sh inbox 3

{
  "n": 1,
  "subject": "Your weekly digest",
  "from": "digest@example.com",
  "date": "2026-01-25T15:44",
  "read": false,
  "id": "icYY6QAIUE26PgAAAA=="
}
{
  "n": 2,
  "subject": "Meeting reminder",
  "from": "calendar@outlook.com",
  "date": "2026-01-25T14:06",
  "read": true,
  "id": "icYY6QAIUE26PQAAAA=="
}

$ ./scripts/outlook-mail.sh read "icYY6QAIUE26PgAAAA=="

{
  "subject": "Your weekly digest",
  "from": { "name": "Digest", "address": "digest@example.com" },
  "to": ["you@hotmail.com"],
  "date": "2026-01-25T15:44:00Z",
  "body": "Here's what happened this week..."
}

$ ./scripts/outlook-mail.sh stats

{
  "folder": "Inbox",
  "total": 14098,
  "unread": 2955
}

$ ./scripts/outlook-calendar.sh today

{
  "n": 1,
  "subject": "Team standup",
  "start": "2026-01-25T10:00",
  "end": "2026-01-25T10:30",
  "location": "Teams",
  "id": "AAMkAGQ5NzE4YjQ3..."
}

$ ./scripts/outlook-calendar.sh create "Lunch with client" "2026-01-26T13:00" "2026-01-26T14:00" "Restaurant"

{
  "status": "event created",
  "subject": "Lunch with client",
  "start": "2026-01-26T13:00",
  "end": "2026-01-26T14:00",
  "id": "AAMkAGQ5NzE4YjQ3..."
}
```

## Token Refresh

Access tokens expire after ~1 hour. Refresh with:

```bash
./scripts/outlook-token.sh refresh
```

## Files

- `~/.outlook-mcp/config.json` - Tenant ID, client ID, and client secret
- `~/.outlook-mcp/credentials.json` - OAuth tokens (access + refresh)

## Permissions

- `Mail.ReadWrite` - Read and modify emails
- `Mail.Send` - Send emails
- `Calendars.ReadWrite` - Read and modify calendar events
- `offline_access` - Refresh tokens (stay logged in)
- `User.Read` - Basic profile info

## Notes

- **Email IDs**: The `id` field shows the last 20 characters of the full message ID. Use this ID with commands like `read`, `mark-read`, `delete`, etc.
- **Numbered results**: Emails are numbered (n: 1, 2, 3...) for easy reference in conversation.
- **Text extraction**: HTML email bodies are automatically converted to plain text.
- **Token expiry**: Access tokens expire after ~1 hour. Run `outlook-token.sh refresh` when you see auth errors.
- **Recent emails**: Commands like `read`, `mark-read`, etc. search the 100 most recent emails for the ID.

## Troubleshooting

**"Token expired"** → Run `outlook-token.sh refresh`

**"Invalid grant"** → Token invalid, re-run setup: `outlook-setup.sh`

**"AADSTS50194"** → App is single-tenant but endpoint used `/common`; use tenant-specific endpoint or re-run `outlook-setup.sh`

**"AADSTS700025"** → App is configured as public client; disable public client flow in App Registration Authentication settings

**"Insufficient privileges"** → Check app permissions in Azure Portal → API Permissions

**"Message not found"** → The email may be older than 100 messages. Use search to find it first.

**"Folder not found"** → Use exact folder name. Run `folders` to see available folders.
