Thanks for the request. Currently there is a way to set this property through powershell for groups, but it only works for users in OWA. We have this in our plans for Outlook desktop as well and will be working on it.

As others said, we need the ability to assign 'read only' access to group calendars so that some people can see calendar event details but cannot edit. It would be handy if they could also receive and accept/decline invitations without being allowed to edit/add/delete events. And it needs to be easy for calendar owners to manage this since we have staff managing group calendars who are not going to use powershell. It seems you could just add 'view event details', 'view event details and accept/decline invitations', and 'view and edit events' as options to assign to group members.
An example of our need is a boat calendar. We have a fleet of boats. All staff need to be able to see what boat trips are scheduled where and when, but we only want our boat managers to edit this calendar. However staff need to be able to accept invitations from boat managers for trips they are passengers on. I am sure this is the type of need that almost all organizations have.Alyssa supported this idea ·
