CCalConverter

Frequently Asked Questions

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.
Why doesn't my Outlook calendar work in Google Calendar directly?
Microsoft 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.
How often does the calendar update?
CalConverter refreshes the converted feed in the background, and Google or Apple then pull the latest version on their own schedule. You don't need to re-import anything.
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.
