What are Outlook Calendar deep links?

Outlook Calendar deep links are specially formatted URLs that allow you to pre-fill event details and open the Outlook Calendar event creation interface directly. When someone clicks on these links, they're taken straight to a new event form with all the information already filled in—title, description, date, time, and location. This eliminates manual data entry and reduces the chance of errors when sharing event information.

Deep links work with both Outlook.com (personal Microsoft accounts) and Office 365 (work and school accounts), though they use slightly different base URLs. The parameters are encoded in the URL query string, making them easy to share via email, messaging apps, websites, or any medium that supports hyperlinks.

How do calendar link generators work?

Calendar link generators construct URLs by encoding event parameters according to the calendar service's API specification. For Outlook, this involves:

  1. Selecting the correct base URL - Outlook.com uses outlook.live.com while Office 365 uses outlook.office.com
  2. Encoding event details - Title, description, location, and dates are URL-encoded and added as query parameters
  3. Handling time zones - Times are converted to ISO 8601 format with proper timezone information
  4. Managing all-day events - These use date-only formats without time components

The resulting link, when clicked, opens the user's Outlook Calendar with a pre-populated event form ready for final review and saving.

Recipients can click the link to open their Outlook Calendar with all event information pre-filled.
