For interim & fractional executives
Multiple engagements, one calendar – zero collisions
Every engagement means a separate account in the client's tenant – and a calendar that knows nothing about the others. Kalender Sync keeps all engagement calendars and your own in real-time sync. Each client only sees "busy" from the rest.
Calendar sync for interim & fractional executives
How Kalender Sync helps across all your engagements
No double-booking between engagements
Whether you run two, three or four engagements in parallel – Microsoft 365 here, Google Workspace there: all accounts come together in real time. A meeting at client A automatically blocks the slot everywhere. At four-figure day rates, every collision is direct revenue and reputation damage – which you can now avoid entirely.
A non-issue in compliance checks
Built in Munich, hosted in Germany, GDPR-compliant, with a DPA for business customers. When your client's IT team or data protection officer asks questions, you already have the answers.
Discretion is built in
Client A never learns who else you work for. Per sync, you decide what comes through: "busy" only, title + time, or full details. Add a custom display name like "External" – and that's all anyone sees.
Cleanly handled from day one to the last day of the engagement
No account in the client's tenant? A shared calendar link via iCal or CalDAV is all it takes. And when the engagement ends, you delete the connection – the sync stops immediately, with no open access and nothing left behind.
