A modern calendar sync solution

Forget about double-bookings or missed meetings with automatic and real-time two-way sync of calendar meetings

Two-way sync

You can sync meetings both two-way and one-way, with any configuration model: user-to-user, one-to-many or many-to-many

Historical data merge

We make sure all of the already scheduled meetings are initially merged and no duplicates are created


Adjust field mapping, apply sync filters, or other rules in any way imaginable, with no line of code in just a couple of clicks

Multi-tenant sync

SyncPenguin allows you to sync meetings between calendars of different Microsoft 365 tenants or devices


None of your meeting data is stored on the server, and the sync is performed in real-time and on the fly
