OnTime Group Calendar
What OnTime Group Calendar is
OnTime Group Calendar is a shared calendar system for teams and departments. It combines calendars in a visual view so people can check availability, locate colleagues, and arrange meetings. The service connects with Microsoft 365, Microsoft Exchange, and HCL Domino. Its scheduling tools include 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 appear in the Microsoft Teams sidebar or selected channels. OnTime for Domino works in HCL Verse and can show users from Domino and Microsoft environments together. An HTTP-based API is available, with existing customers needing a license key from the company. Domino users can apply individual permissions and keep private event details visible only to themselves. Platforms include Android, iOS, Linux, Windows, web, API, and self-hosted deployments. Freemium Level 1 is free for up to 25 users; Level 2 is free for up to 50 users with current HCL Domino CCB.
