Microsoft export/import
Export an Outlook .ics file, import it into Google Calendar, and you have a static snapshot of the calendar at that moment.
Calendar Syncer continuously syncs your Microsoft Outlook calendar one way into Google Calendar. New invites, reschedules, cancellations, and deletes land typically within about a minute of Outlook's change notification — not the 12–24 hours a subscribed calendar takes. Nothing is ever written back to Outlook.
No credit card required — the free trial starts with your first sync.
Microsoft's official Outlook export/import flow can move a calendar into Google once. It does not keep future Outlook meetings, edits, cancellations, or deletes flowing.
Export an Outlook .ics file, import it into Google Calendar, and you have a static snapshot of the calendar at that moment.
Connect once and keep Outlook changes continuously synced into Google Calendar as one-way shadow events.
One-way by design: Outlook stays the source of truth, and Google Calendar becomes a complete, current view of your day. No write-backs, no duplicate loops, no published links to manage.
Sign in with Microsoft. Your Outlook calendar is only ever read — nothing is created, changed, or deleted on the work side.
Synced meetings land in a dedicated calendar the app creates, so your primary Google calendar stays untouched. Prefer an existing calendar? The advanced flow allows that too.
New invites, reschedules, cancellations, and deletes appear in Google Calendar typically within about a minute of Outlook's change notification — with an hourly reconciliation sweep catches anything a notification misses.
Reliable sync requires storing some state — encrypted tokens, event mappings, sync logs. Instead of claiming “we store nothing”, here is exactly what is stored and why. OAuth tokens and cached event data are encrypted at rest, sync data is deletable from Settings, and operational logs are kept only for a short retention window.
$9/month after a 14-day free trial — no credit card required to start. Built for one person, up to three Outlook calendar connections, and straightforward monthly billing.
Connect both accounts with OAuth — about two minutes, no exports or published links. Calendar Syncer then keeps an auto-updating copy of every Outlook event in Google Calendar, typically within about a minute of each change. Free methods exist too; the built-in URL subscription updates only every 12–24 hours.
No — one-way by design, from Outlook into Google Calendar. Outlook stays the source of truth and is never modified, which keeps work calendars safe from write-backs and personal events out of the corporate directory.
Typically within about a minute. Microsoft notifies the service the moment an event changes, the sync runs immediately, and an hourly reconciliation sweep backs up anything a notification misses.
Yes for personal outlook.com accounts, and for Microsoft 365 work/school accounts in most organizations. IT disabling calendar publishing doesn't block it, because the sync uses Microsoft's standard OAuth consent instead of published ICS links — though tenants that restrict third-party app consent may route the request to your admin for approval first.
$9/month flat after a 14-day free trial, including up to three connected Outlook calendars. No credit card is required for the trial — it starts with your first sync. Billing runs through Stripe and you can cancel future renewals anytime from the customer portal.
Into a dedicated calendar the app creates, so your primary Google calendar stays untouched. You can toggle its visibility per device or delete it entirely — advanced setup also allows syncing into a calendar you already own.
