MEM_CreateGroups

Script designed to automate the creation of Azure AD (Microsoft Entra) Dynamic Groups. Uses a CSV file to define group attributes and can operate across multiple tenants. I use script in Microsoft Intune projects to to automate group creation of base or initial groups.

Features

• CSV-Driven Group Creation: Utilizes a CSV file to define group attributes such as name, description, membership rules, and more.

• Multi-Tenant Support: The script allows for the specification of a Tenant ID, enabling operations across different Azure AD tenants.

• Module Validation: Validates and installs the required AzureAD or Az PowerShell modules.

• Error Handling: Robust error checking and validation mechanisms are in place.

Prerequisites

• Administrative privileges on the machine where the script is run.
• AzureAD or Az PowerShell module.

Usage

With Tenant ID

.\MEM_CreateGroups.ps1 -GroupsFile .\YourGroupsFile.csv -TenantId "your-tenant-id"

Without Tenant ID

.\MEM_CreateGroups.ps1 -GroupsFile .\YourGroupsFile.csv

Certainly! Here's the updated section on the CSV file format, based on the details from the original script:

CSV File Format

The CSV file should contain the following headers:

• GroupType: The type of the group (e.g., Security, Office365).
• GroupDisplayName: The display name for the group.
• GroupDescription: A description for the group.
• GroupMembershipType: The membership type. Acceptable values are "AA" for assigned groups, "DD" for Dynamic Device groups, and "DU" for Dynamic User groups.
• GroupMembershipRule: The membership rule in OData format.
• GroupOwner: The owner of the group (optional).

Here's a sample CSV file content:

GroupType,GroupDisplayName,GroupDescription,GroupMembershipType,GroupMembershipRule,GroupOwner
Security,HR Team,Human Resources Team,DU,(user.department -eq "HR"),john.doe@domain.com

Output

• Azure AD Groups: Dynamic groups are created in the specified or default Azure AD tenant.
