Notes

• Tokens expire; use refresh tokens or app-only auth for long-running operations.
• Delegated tokens act on behalf of a user; application tokens act as the app.
• Use $select, $filter, $top, $orderby OData query params for efficient queries.
• Always confirm before sending emails, creating events, or posting messages.
