Why people pick SyncThemCalendars
Your PC is no longer the sync server
Desktop sync tools only work while the machine is on and the app is running. A cloud sync keeps your calendars aligned during your commute, your vacation and your laptop's sleep.
Modern Microsoft accounts, no desktop Outlook needed
Works directly with Microsoft 365 and Outlook.com accounts through Microsoft's cloud APIs - whether or not you have classic desktop Outlook installed anywhere.
Apple iCloud included
Bring your personal Apple calendar into the same setup - sync it with Google or Outlook, one-way or two-way, with the same privacy controls.
When Sync2 might fit you better
If you prefer a one-time license over a subscription, work fully inside classic desktop Outlook on a Windows PC that's always on, and want everything to run locally, Sync2's model can suit you.
Switching takes minutes
Start your free trial
14 days, no credit card. Connect your Google, Outlook or Apple iCloud accounts in your browser.
Recreate your syncs
Pick each source and target calendar, choose one-way or two-way, and set your privacy options. About 2 minutes per sync.
Turn off the old tool
Once you see events flowing, pause or cancel your previous tool so the two don't copy the same events side by side.
Frequently asked questions
Do I need to install anything to use SyncThemCalendars?
No. You connect your calendar accounts in the browser and the syncing runs in the cloud from then on. There is no agent, no desktop app and nothing to keep updated.
Does it work with desktop Outlook?
It syncs the Microsoft 365 / Outlook.com calendar behind it, via Microsoft's cloud APIs. Desktop Outlook, the new Outlook, mobile Outlook and the web all show the same synced calendar.
I'm on a Mac - is that a problem?
Not at all. SyncThemCalendars is a web service, so it works the same on Mac, Windows, Linux and mobile.
Ready for calendar sync that just works?
Set up your first sync in 2 minutes. Google, Outlook and Apple iCloud, one-way or two-way, with your privacy protected.
