Google Calendar Shows Wrong Times for Outlook Events — Timezone Fix

Your Outlook calendar finally shows up in Google Calendar — but every meeting is an hour off, or shifted by several hours. This is almost always a time-zone problem baked into Microsoft's feed.

Why the times are wrong

The iCalendar standard expects time zones to be defined with IANA names (like Europe/Berlin or America/New_York) and a matching VTIMEZONE block that tells the client exactly how to convert each timestamp.

Microsoft 365 instead labels events with Windows time-zone names like W. Europe Standard Time and often omits a proper VTIMEZONE definition. Google Calendar then guesses — and guesses wrong, especially around daylight-saving changes. The event lands at the wrong hour.

Why you can't fix it in Outlook

There's no Outlook setting that switches the published feed to IANA time zones. The fix has to happen in the feed itself: the Windows zone has to be mapped to the correct IANA zone, and a valid VTIMEZONE block added.

The fix

That mapping and repair is exactly what CalConverter does. It rewrites W. Europe Standard Time to Europe/Berlin, injects a correct VTIMEZONE, and serves a clean feed — so Google places every event at the right time.

Steps

1. Publish your Outlook calendar and copy the .ics link.
2. Convert it with CalConverter.
3. Replace your existing Google subscription with the converted URL (remove the old one so you don't see duplicates).

After that, events show at their real local time and stay correct through daylight-saving transitions.
