Office 365 Group Calendars permissions


I am pretty new to the Offcie 365 group functionality:

I wanted to ask if there is a possibility to set the group calendar in O365 with different permissions?

My usecase:

We have a large group of teachers here in my school and we want to have a group calendar where only some of the teachers are allowed to create and modify events. So my questions is, if and where I can set the group calendar permissions?

(I have managed to create permissions for the group's OneNote notebook and OneDrive (as it is all a SharePoint site, so where is the calendar stored on this SharePoint site?)

Another thing is: Is it possible to turn of the invitations or notifications for all group members? It is a bit annoying if at school year start over 120 events are created and everybody gets 120 event invitations?

Another thing:

I want to customize the group menu header, (Conversations, Files, Calendar, Planner,...) Is this possible within the O365 groups?

Many thanks


Hi Kurt,

For the first query, it’s not feasible to set group calendar permissions for specific users in Office 365 groups. When you join a group, your email address is automatically added to the distribution list and you gain access to all group information including the group calendar for scheduling group meetings and events. Thanks for your understanding. Here is a relevant article for your reference:

Also, you are welcome to vote for the feature via the following link:

For the second one, I have done some tests with Outlook Web App as an example. I found that I can untick the option ‘Send an invitation to the group’ when creating an event in the group calendar and notifications or invitations would not be sent in this case.

However, if I specified a room while creating the event, the option became greyed out and it’s not feasible to untick the option in this situation:

So could you let me know whether you ticked the option while creating those 120 events previously or the option simply could not be modified as you chose rooms at that time?

As for customizing the group menu header, do you want to customize the menu bar in the picture below?

If so, I have done some tests but couldn’t find any official articles about it. Your understanding is highly appreciated. Meanwhile, I suggest you submit feedback for the feature via the link below:

Let me know if anything is misunderstood.
