Yes, if you’re building a modern app or integration, Microsoft Graph is generally the recommended way to access Outlook calendar data.

Use Microsoft Graph if you want to:

  • Read/write calendar events
  • Access calendars for Outlook.com, Microsoft 365, or Exchange Online users
  • Build web, mobile, or backend apps
  • Use OAuth 2.0 / Azure app registration
  • Work with one API for Outlook, mail, contacts, etc.

You might not need Microsoft Graph if:

  • You’re only working with Outlook desktop add-ins or VBA/COM automation
  • You’re using older legacy APIs like Exchange Web Services (EWS) or Outlook REST API
    • Note: Outlook REST API is deprecated
    • EWS is still around in some environments but generally not the preferred choice for new development

Rule of thumb

  • New development: use Microsoft Graph
  • Legacy/internal desktop automation: maybe not, depending on the tool and environment

If you want, I can also tell you which API to use based on your exact scenario (web app, Python script, Outlook add-in, Power Automate, etc.).

Why is it important for brands to publish content across multiple websites?

Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
