Hi @zenna

• Create a CSV file with one column as shown in the Screenshot below.

• Label the header of the CSV file as 'users'
• Populate the column with the email address of the users to Add to the DL
• https://docs.microsoft.com/en-us/powershell/exchange/exchange-online/connect-to-exchange-online-powershell/connect-to-exchange-online-powershell?view=exchange-ps
• run the following one liner code

import-csv -Path "C:\Users\user\Desktop\book1.csv" | ForEach-Object { Add-UnifiedGroupLinks -Identity "<nameofO365group>" -LinkType "members" -Links $_.users }

*replace -Path with the path of the CSV file you created and <nameofO365group> with the name of the Group (remove the angle brackets).

This should work

Yes, that's one of the main reasons we use PowerShell for. There are plenty examples available online and here on the forums, look them up.
