Azure AD: Out-Null isn't working

Hello.

I hope I found the right place to put this thread. I'm not used to the new forums setup yet.

I am running this command to add a user to an AAD group:
Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID

It adds the user just fine. No issues there. But I have this in a script and I don't want the output from adding the user. I just want the cmd to run and not give me the details (I'm pulling the information later in the script and the output from this just clogs up the screen).

I've tried:

  1. Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID | Out-Null
  2. $Null = Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID
  3. Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID > $null
  4. and even: [void] Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID

It still outputs the information.

Is there a way to make it not dump the info to the screen?

Thanks!

    Hi @Dale Peterson ,

    there are 2 options you can try: 

    # option 1:  
(Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID) > $null  
  
# option2:  
Add-AzureADGroupMember -ObjectID $RetGroup.ObjectID -RefObjectID $RetUser.ObjectID | Out-Null

    ----------

    Given the different methods you've tried leads me to believe that the output you see isn't sent to the "Success" stream (a.k.a. STDOUT).

    Check the value of these variables:
    $ErrorPreference
    $WarningPreference
    $VerbosePreference
    $DebugPreference
    $InformationPreference

    You can experiment to discover the stream that's sending the information to the screen by redirecting each stream (one at a time) to the Success stream and piping the output to "Out-Null". 

    Add-AzureADGroupMember . . .  2>&1 | Out-Null    # Error
Add-AzureADGroupMember . . .  3>&1 | Out-Null    # Warning
Add-AzureADGroupMember . . .  4>&1 | Out-Null    # Verbose
Add-AzureADGroupMember . . .  5>&1 | Out-Null    # Debug
Add-AzureADGroupMember . . .  6>&1 | Out-Null    # Information
Add-AzureADGroupMember . . .  *>&1 | Out-Null    # All streams
