OnTime Group Calendar brings calendars into a shared visual view so teams can check availability, find people, and arrange meetings.
What OnTime Group Calendar is
OnTime Group Calendar brings calendars into a shared visual view so teams can check availability, find people, and arrange meetings. It integrates with Microsoft 365, MS Exchange, and HCL Domino, and includes calendar views, a meeting assistant, online meetings, delegated scheduling, time-off planning, polls, availability links, and calendar data export. OnTime for Microsoft is embedded in Outlook and can be added to the Microsoft Teams sidebar or particular channels. The Domino version is available in HCL Verse and can combine users from Domino and Microsoft environments. OnTime also offers an HTTP-based API, though existing customers must contact the company for a license key. Its full-featured trial runs for 60 days, then expires and stops working. Limited-feature freemium options include perpetual access for up to 25 users at Level 1, and a subscription-based Level 2 for up to 50 users that requires current HCL Domino CCB. Licensing is required for each person, room, resource, or shared desk configured and used in an OnTime view.
