Add-EngageGroupAdmins

What it is

A PowerShell sample that reads a CSV of Microsoft 365 group IDs and user email addresses and adds each user as an owner of the group behind a Viva Engage community by calling Microsoft Graph. Group owners are treated as admins of the associated community.

Why use it

• Add community admins in bulk instead of one community at a time.
• Uses the documented Microsoft Graph group owners API with app-only authentication and waits and retries when Graph throttles requests.
• Prints a success or failure message for every CSV row.

How to use it

1. Create a Microsoft Entra app registration with the Microsoft Graph Group.ReadWrite.All application permission and grant admin consent.
2. Create a CSV with a GroupID column (the Microsoft 365 group ID behind the community) and an Email column (the UPN of the user to make an admin).
3. Set $groupadminsCsvPath, $ClientId, $TenantId, and $ClientSecret near the top of the script.
4. Run:

.\Add-EngageGroupAdmins.ps1

Prerequisites

• Microsoft Entra app registration with the Group.ReadWrite.All application permission and admin consent
• CSV with GroupID and Email columns; GroupID is the Microsoft 365 group GUID, not the legacy numeric Yammer group ID
