Run the following command to add members: Add-UnifiedGroupLinks -Identity "O365GroupName" -LinkType Members -Links user1@contoso.com,user2@contoso.com

Verify membership

Check the Microsoft 365 admin center or use the Get-UnifiedGroupLinks cmdlet to ensure the users were successfully added to the group.

Frequently Asked Questions

Can I automate Microsoft 365 group creation using Power Apps?

While Power Apps is great for building custom interfaces, complex group creation automations are often better handled using Power Automate (Flow) by calling the Microsoft Graph API. You can visit the Power Apps Community forums for specific workflow triggers.

What licenses are required for dynamic groups in Microsoft 365?

Using dynamic groups requires Microsoft Entra ID P1 or P2 (formerly Azure AD Premium) licenses for the administrators creating the rules, as well as for all users who are dynamically assigned to the group.

Is there a way to bulk import members to a Microsoft 365 group using a CSV?

Yes, you can format a CSV file with user email addresses and write a short PowerShell script to loop through the CSV rows, applying the Add-UnifiedGroupLinks cmdlet to bulk add all users at once.
