Shared Calendar & Planner offers the integration to all the calendars supporting ICS links, e.g. Google Calendar, Outlook and Apple Calendar.
Subscribed calendars (using ICS/iCal links) do not sync in real-time. Google Calendar generally updates external subscriptions every 8β9 hours, while Outlook (web and desktop) typically updates every 3 to 24 hours. These syncs are one-way and can take up to 24 hours to reflect changes from the source calendar.
All the events from Shared Calendar & Planner will be mirrored in your other calendars, not vice versa. To edit Shared Calendar & Planner events you should use the app via Microsoft Teams or via web link.
