Built by one person who had this exact problem.

Why this product exists

For years my meetings arrived in a work Outlook account while everything else in my life lived in Google Calendar. The free fixes all disappointed in the same ways: the exported .ics file was stale the moment something got rescheduled, and the subscribed calendar updated somewhere between twelve and twenty-four hours too late. I first built myself a scrappy scripted bridge, then decided to build the real thing — continuous, one-way, boring-in-a-good-way sync from Outlook into Google Calendar.

The principles the product is built on

• One direction, on purpose. Outlook is the source of truth; nothing is ever written back to it. Why one-way.
• Narrow permissions. Read-oriented access on the Microsoft side, writes into an app-created calendar on the Google side. How it works.
• Honest data disclosure. Continuous sync requires storing sync state; the security page lists exactly what is stored instead of pretending nothing is.

The business

Calendar Syncer is operated by Philip Reichen Software, a Swiss sole proprietorship (Einzelunternehmen) at Hohlstrasse 206, 8004 Zurich, Switzerland. You can reach me directly at philthebrogrammer@gmail.com — support mail lands in my inbox, not a queue. The company is also on LinkedIn.
