Re: Managing environment permissions with Security/Office Groups
@v-siky-msft Thanks. Please see the steps below
Go to https://admin.powerplatform.microsoft.com/environments > Select the environment you want to use > Settings > Under Users and Permissions select 'Teams'
Select New and populate the following fields:
Team Name
Administrator
Team Type > AAD Office Group
Azure AD Object Id for a group > Object Id of group
Select Save
Once Saved select Manage Roles > I was choosing either System Administrator or Environment Maker
From your statement it seems to imply that you cannot assign Environment Maker or System Administrator using a security group. Does that mean the Microsoft - Establishing an environment strategy article refer to something else when referring to security groups? https://powerapps.microsoft.com/en-us/blog/establishing-an-environment-strategy-for-microsoft-power-platform/

The environment strategy article (Link above) suggests that the Project dev security group are environment makers. Is it a case that what they are referring to is environments which don't have a CDS database? That way you can assign a security group to that role? If that is the case it would be good to point it out so it is clear. The same article also states
Share resources with Azure AD Security Groups
Security Groups can be used to manage access to PowerApps, Flows, Common Data Service security roles
Are the Environment Maker and System Administrator roles not considered as Common Data Service security roles?
Thanks for your help.
