title: Updating Multiple Users to ADGroup
body: <p>I'm trying to update AzureADGroupMember for multiple users in a CSV File by UPN. </p>
  
  <p>This is what I've came across and attempted:</p>
  
  <pre><code>$users = Import-csv "C:\Temp\testgroup2.csv" 
  
  $users | ForEach-Object{
  Add-AzureGroupADGroupMember -ObjectId xcv9890-stest999-xcvxc234-xcv2342324 
  -RefObjectId (Get-AzureADUser -ObjectId $_.UPN).ObjectId
  }
  </code></pre>
  
  <p>I get the following 2 errors.</p>
  
  <pre><code>Import-csv : The member "Role" is already present.
  At line:1 char:10
  
  Get-AzureADUser : Cannot bind argument to parameter 'ObjectId' because it 
  is null.
  At line:4 char:120
  </code></pre>
  
  <p>Any idea why this keeps happening? I would really appreciate the help.</p>
  
  <p>Thank you,</p>
