Which service integrates Office 365 calendars with Webex for scheduling?

• A. Outlook Connector
• B. Hybrid Calendar Services
• C. Webex Scheduling Engine
• D. Calendar Sync Service

Answer: (B)

Connecting Webex with Office 365 calendars for scheduling relies on a bridge that can handle calendar data across hybrid environments. Hybrid Calendar Services acts as that bridge, enabling Webex to access Office 365 calendars to check availability, create and update events, and push Webex meeting details into attendees’ calendars. This service handles the synchronization and permissions needed so a Webex meeting shows up properly in users’ Outlook calendars and reflects updates in real time.

The other options don’t provide that comprehensive, two-way calendar integration in a hybrid or cloud-based Office 365 scenario. Outlook Connector implies a more limited or older link to Outlook, while Calendar Sync Service is a more generic term that doesn’t specify the full Office 365/Webex synchronization flow. Webex Scheduling Engine is the scheduling mechanism itself, but it relies on the calendar integration layer (provided by Hybrid Calendar Services) to interact with Office 365 calendars.
