Add members to O365 Security Groups using Azure AD Powershell Module

Step 1. Create a CSV file with a column “UserPrincipalName” and add all users under it who are to be added as a member of the group.


Step 2.  Run The below command to import the csv file and get the object IDs for members to be added to group

Import-Csv C:\temp\Members.csv csv  | Foreach {Get-Msoluser -UserPrincipalName $_.Userprincipalname | select Objectid } | Export-csv C:\temp\MembersWithObjectID.csv

This will convert the user’s identity to their unique guid details, and export it to the same CSV file.
