We are using Outlook 2016, Exchange Online and Microsoft Teams and have a Team/Office 365 Group with approx. 60 users. We would like each member to share their calendar with the rest of the team members. In Outlook when I try to grant permission to the Team/Office 365 Group under Calendar Properties -> Permissions I get an error says it is not possible to grant permission to this kind of group. If I use a regular Security-enabled Distribution Group it works fine. So, it looks like an Office 365 Group is not usable for this. Is there anyone that has any suggestions how I can solve this? Creating a new Distribution Group and manage the members manually is not an option.
I have tried to security enable the Azure Group, using the following command, but it didn't help.
Set-AzureADGroup -ObjectId "270f9668..." -SecurityEnabled $True
