In this video, Adam looks at how you can create mail-enabled security groups via PowerShell and copy members from an Office 365 Unified group into that new group. This came about based on a limitation that within Power BI, you can’t list O365 Unified groups (what back App workspaces) from the people picker for access or sharing. To get around this with a customer, we suggested creating a mail-enabled security group and copying the members to that new group.
The mail-enabled security group will show up in the people picker.
Make sure you have installed the Azure AD 2.0 PowerShell module to use this script. You will also need to have access to Exchange Online and be an admin.
