Why pasting Outlook URLs into Google Calendar fails

Microsoft 365 publishes calendar feeds with Windows time-zone names (like "W. Europe Standard Time") and timestamps that Google Calendar cannot parse. The result: the calendar either won't add at all, or events show up at the wrong time. CalConverter rewrites the feed into a clean, standards-compliant ICS that Google accepts and keeps refreshing.

How to add it (the reliable way)

  1. 01

    Publish your Outlook calendar

    In Outlook on the web, go to Settings → Calendar → Shared calendars, publish the calendar with "Can view all details", and copy the ICS link.

  2. 02

    Convert the link

    Paste the ICS link into CalConverter and copy the Google-compatible URL it gives you.

  3. 03

    Subscribe in Google Calendar

    In Google Calendar, choose Other calendars → Subscribe from URL, paste the converted URL, and save.

It stays in sync

Google refreshes subscribed calendars on its own schedule. CalConverter keeps the converted feed up to date in the background, so new and changed events keep flowing through without re-importing anything.
