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.
