  Not sure on 1st query.

  2nd Query you can do it via below shell command

  $a = gc "distributiongroup.txt"

  $a | set-DistributionGroup | {$_.RequireSenderAuthenticationEnabled -eq $false}

  Hi,

  No easy one command to get all nested groups in one main group (It's easy for nested members in one group). Here is my suggested procedure.
  

  Run this command on main group to get the groups in the main group and uncheck sender authenticaiton at the same time.
  

  Get-DistributionGroupmember MainGroup | ?{$_.RecipientTypeDetails -like "*group*"} | Set-DistributionGroup -RequireSenderAuthenticationEnabled $false
  

  Then replace Maingroup to the group in the result of the command above. Do the same on layer down until the last layer.
  

  Example:

  
  

  Step1:    Get-DistributionGroupmember MainGroup | ?{$_.RecipientTypeDetails -like "*group*"}| Set-DistributionGroup -RequireSenderAuthenticationEnabled $false

  Step2:    Get-DistributionGroupmember Group1 | ?{$_.RecipientTypeDetails -like "*group*"}| Set-DistributionGroup -RequireSenderAuthenticationEnabled $false

  Step3:    Get-DistributionGroupmember Group3 | ?{$_.RecipientTypeDetails -like "*group*"}| Set-DistributionGroup -RequireSenderAuthenticationEnabled $false

  Step4:    Get-DistributionGroupmember Group5 | ?{$_.RecipientTypeDetails -like "*group*"}| Set-DistributionGroup -RequireSenderAuthenticationEnabled $false

  It will be a lot of work if there are too many nested groups.

  Best Regards.
