Frequently Asked Questions
How does Kalendarius connect to Microsoft 365 and Outlook?
Kalendarius connects securely via the official Microsoft Graph API using OAuth 2.0. No Exchange passwords are ever stored, and organizational tenant administrators can grant secure, scoped consent.
Can Kalendarius automatically create Microsoft Teams meeting links?
Yes. When an invitee books a time slot, Kalendarius can automatically generate a unique Microsoft Teams meeting room URL and include it directly in the Outlook calendar invitation and email confirmations.
Is Kalendarius compliant with enterprise data residency requirements for Microsoft 365?
Kalendarius hosts its core application and database with Hetzner in the EU, and Business and Enterprise customers can obtain a signed Article 28 DPA. This does not create immunity from all foreign legal process: customers must also assess their Microsoft tenant, connected services and organizational requirements.
Can I use Kalendarius with both Outlook and personal Google calendars simultaneously?
Yes. Kalendarius allows you to connect multiple calendar providers simultaneously, checking availability across both Outlook and Google Calendar to eliminate scheduling conflicts across personal and professional commitments.
