- Is CalConverter free?
- Yes. Converting your Microsoft 365 calendar and keeping it in sync is free to use.
- Do I need to create an account?
- No. You paste your Outlook ICS URL, get converted Google and iCloud URLs back, and subscribe — no sign-up, no login.
- Is this for Office 365 or Microsoft 365?
- Both — they are the same product. Microsoft renamed Office 365 to Microsoft 365, and the calendar feed works identically either way. CalConverter handles any Outlook, Office 365 or Microsoft 365 published ICS link.
- Why doesn't my Outlook calendar work in Google Calendar directly?
- Microsoft 365 (Office 365) publishes feeds with Windows time-zone names and timestamps Google can't parse, so the calendar fails to add or shows wrong times. CalConverter rewrites the feed into a clean, standards-compliant ICS.
- My Outlook events show the wrong time (off by an hour or more) in Google or on my iPhone — why?
- That is the Windows time-zone problem: Microsoft publishes feeds with names like "W. Europe Standard Time" that Google and Apple read as UTC, so every event shifts by the time-zone offset. CalConverter rewrites the feed with standard IANA time zones and valid VTIMEZONE blocks, so the times come out correct.
- Is this a real two-way integration, or one-way?
- It is a one-way subscription: your Office 365 / Microsoft 365 events flow into Google Calendar and Apple Calendar and stay updated, but changes you make in Google or Apple do not flow back to Outlook. If you only need to see your work calendar correctly on another device, a clean one-way feed is exactly what you want — it never creates the duplicate or conflicting events two-way sync tools are known for.
- Can it sync Google Calendar to Office 365 (the other direction)?
- CalConverter converts in the Outlook / Office 365 → Google and Apple direction. To see a Google calendar inside Outlook, publish the Google calendar's secret ICS address (Google Calendar → Settings → your calendar → Integrate calendar) and add it in Outlook on the web via Add calendar → Subscribe from web.
- How often does the calendar update — can I make it faster?
- CalConverter refreshes the converted feed automatically in the background, and Google or Apple then pull the latest version on their own schedule — you never re-import anything. Faster, near-real-time refresh is planned as a paid option; follow the News page for updates.
- Is my calendar data stored?
- CalConverter caches the calendar feed so it can serve it quickly and keep it refreshed. It does not require your Microsoft account credentials — only the public ICS sharing link you provide.
- Which calendars are supported?
- Microsoft 365 and Outlook published ICS links (outlook.office365.com, outlook.office.com, outlook.live.com).
- My converted calendar stopped updating — what happened?
- The most common cause is that the original Outlook publish link was reset or revoked. Re-publish the calendar in Outlook, then convert the new link again.
- Can I use this for my whole team?
- Yes — each person can convert their own calendar. Team features are on the roadmap; follow the News page for updates.
