About OMC

Calendar coordination, for personal use.

Last updated October 26, 2026

OMC (Outlook Multi-Context) helps Robert Igarashi coordinate calendars across his own authorized accounts.

One view of a busy day

OMC reads selected calendars and, when synchronization is enabled, creates configured detail copies in a master calendar and generic availability blocks in other selected calendars. It uses tracking information to maintain those managed copies.

A personal utility

Robert operates OMC solely for his own authorized accounts. This website provides information about the utility; it does not offer public registration or access to connected accounts.

Google Calendar access

OMC requests access to view the calendar list and to view and edit calendar events. Calendar selection and application settings determine which calendars act as sources and which receive managed copies. A source-only calendar is not a managed destination.
