Outlook

Outlook Skill

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

Quick Setup (Automated)

# 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 to ~/.outlook-mcp/

Manual Setup

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

Multiple Accounts

You can connect multiple Outlook accounts (personal, work, etc.):

Setup additional accounts

./scripts/outlook-setup.sh --account work
./scripts/outlook-setup.sh --account personal

Use specific account

./scripts/outlook-mail.sh --account work inbox
./scripts/outlook-calendar.sh --account personal today
./scripts/outlook-token.sh --account work refresh

Or use environment variable

export OUTLOOK_ACCOUNT=work
./scripts/outlook-mail.sh inbox

List configured accounts

./scripts/outlook-token.sh list

Credentials are stored separately:

~/.outlook-mcp/
  default/
    config.json
    credentials.json
  work/
    config.json  
    credentials.json

Existing single-account setups are auto-migrated to default.

Usage

  "id": "AAMkAGQ5NzE4YjQ3..."
}

Token Refresh

Access tokens expire after ~1 hour. Refresh with:

./scripts/outlook-token.sh refresh

Files

• ~/.outlook-mcp/config.json - Client ID and 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

"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.

Supported Accounts

• Personal Microsoft accounts (outlook.com, hotmail.com, live.com)
• Work/School accounts (Microsoft 365) - may require admin consent

Security Considerations

• Azure App Registration: The automated setup creates an App Registration in your Azure tenant with the following permissions: Mail.ReadWrite, Mail.Send, Calendars.ReadWrite, offline_access, User.Read
• Local credential storage: Client ID, client secret, and OAuth tokens are stored in ~/.outlook-mcp/ with chmod 600
• Token printing: outlook-token.sh get --confirm prints access tokens (requires explicit confirmation flag)
• Prerequisites: Requires Azure CLI (az) and jq

If you prefer not to use automated setup, follow the manual configuration in references/setup.md.
