As the person creating an event, simply create an Appointment (in Outlook 2016) or an event with no attendees in Outlook on the web with the “Send a meeting invitation to group members” unchecked.
Doing so will make sure the events stay only in the Group calendar, and is perfect for FYI items like out-of-office.David Robinson commented
It would be good for members of a group to be able to Opt-Out of group calendar events showing in their personal Calendars. Some Groups use events as an FYI for the members, but do not expect members to attend. I can see the events in the Group Calendar, but don't want it on my personal calendar.
Thanks for this request. We are rolling out the links to planner boards for groups in Outlook desktop from the group card, so that should help get to the planner task list.
This request seems to be asking for the Outlook desktop tasks list to also show planner tasks. Can you help us understand the use cases and details on the actions you expect to perform with planner tasks in Outlook?
Thanks.David Robinson commented
I would want Planner Tasks ASSIGNED TO ME to appear in my Outlook Tasks and my To DO (not sure why we have both). I'd want one place to see all my tasks (and where they came from) at a glance.
