How long does it take to connect Cal.com to Microsoft 365?

Most Cal.com to Microsoft 365 integrations are completed within 2 weeks. We start with a discovery session to understand your specific workflow, then build and test the integration. Complex setups with custom business logic may take up to 4-8 weeks.
