What is an ICS file?

An .ics file — short for iCalendar — is the universal file format for sharing a calendar event between applications. It's a plain‑text file defined by RFC 5545 and contains everything about an event: title, start and end time, timezone, location, description, attendees, reminders, and recurrence rules.

Because it's an open standard, .ics files are read by every major calendar — Microsoft Outlook, Outlook.com, Outlook 365, Microsoft 365, Google Calendar, Apple Calendar, Yahoo, Thunderbird and dozens more. If you've ever clicked an "Add to Calendar" link in an email, you've probably downloaded an .ics file.

Why convert ICS to an Outlook link?

Outlook can import .ics files natively, but the experience is rough for a single event. The recipient has to download the file, find it in their downloads folder, double‑click to open it, and pick a destination calendar. For a one‑off invite — a webinar, a launch, a meeting — that's a lot of friction.

A direct Outlook calendar link skips every step. One click and the event opens inside Outlook with the title, time, location, description and timezone already filled in. It's the cleanest way to share a single event with anyone using Outlook.com, Outlook 365, or Microsoft 365 — and it works in any browser, on any device.

Outlook.com vs Outlook 365

Microsoft runs two separate Outlook calendar services. They look almost identical but live on different domains and use different sign‑in flows.

Outlook.com

Outlook.com

For personal Microsoft accounts at outlook.live.com. Use if your email ends in @outlook.com, @hotmail.com, or @live.com.

Outlook 365

Outlook 365

For work or school accounts on Microsoft 365 at outlook.office.com. Use if your company runs Office 365.

Unsure which one your recipient uses? Generate both links from the tool above and share the one that matches their account. The toggle inside the result panel switches between them instantly without reparsing the file.

Manual import: ICS file into Outlook

Outlook for Mac

How to import an .ics file into Outlook for Mac

  1. 1.Open Outlook and switch to the Calendar view.
  2. 2.From the menu bar choose File → Import.
  3. 3.Select Calendar file (.ics) and click Continue.
  4. 4.Locate your .ics file and click Import.

Tip: you can also double‑click an .ics file in Finder — macOS will offer to open it in Outlook if it's your default calendar app.

Outlook for iOS & Android

How to open an .ics on the Outlook mobile app

  1. 1.Receive the .ics as an email attachment or download it to your device.
  2. 2.Tap the file and choose Open with Outlook (or set Outlook as your default calendar app).
  3. 3.Outlook opens the event preview. Tap Add to calendar and pick a destination.

On mobile, links generated by this tool work the same way: tapping Open in Outlook launches the Outlook app if it's installed.

Heads up. Manual import is the right move when the .ics contains a recurring series, multiple events, or attachments — those don't fit in a deeplink URL. For a single one‑off event, the converter above is faster for everyone involved.

Questions

Yes. No signup, no limits. The tool runs entirely in your browser and we don't charge or gate anything.
No. The .ics is parsed in your browser with the open‑source ical.js library. Refresh the page and every trace is gone.
Outlook.com is for personal Microsoft accounts (outlook.com, hotmail.com, live.com). Outlook 365 is for work or school accounts on Microsoft 365. Unsure? Generate both — the toggle inside the result panel switches instantly.
Yes. Times are converted to UTC in the generated link (matching the same approach we use across the app) so Outlook displays the event at the right local time for every recipient — no matter where they are.
Outlook's deeplink format doesn't expose recurrence rules. The generated link will represent the first instance of the series. For the full series, use the manual import steps above to load the .ics directly into Outlook.
Yes — copy the link from the result panel and paste it into any email, button, newsletter, or "Add to Calendar" CTA. If you need a single link that supports Google, Apple, Yahoo and ICS too, take a look at CalGet's full add‑to‑calendar links.
