  • Question

  • Hello.

    I'm working on a script to change "msExchHideFromAddressLists" attribute automatically for disables users in a specific OU.

    $ou = " ""--"" "
    Get-ADUser -SearchBase $ou -Filter * -Properties * | foreach {Set-adUser $_ -Add @{msExchHideFromAddressLists="TRUE"}}

    But I receive an error.  Where I have mistaken?

  • $ou = "OU=()Disabled,OU=2,DC=1,DC=local"
    Get-ADUser -SearchBase $ou -Filter * -Properties * | foreach {Set-adUser $_ -Add @{msExchHideFromAddressLists="TRUE"}}

    and recive that: 

    Set-adUser : Multiple values were specified for an attribute that can have only 
    one value
    At line:2 char:63
    + ... * | foreach {Set-adUser $_ -Add @{msExchHideFromAddressLists="TRUE"}}
    +                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  • Hi, 

    You may use -Replace instead -Add

  • Too many mistakes and too much code:

    $ou = 'OU=()Disabled,OU=2,DC=1,DC=local'
    Get-ADUser -SearchBase $ou -Filter * | 
        Set-adUser -Replace @{ msExchHideFromAddressLists = $true }

    Don't superstitiously add items to code without understanding what they do.  Take some time to learn the basics of PowerShell and you will save a lot of time.

    NEVER use the strings "TRUE/FALSE" for a Boolean.  You must use either "$true/$false" or the numbers 1/0.  Never place quotes around a Boolean.

    The string "FALSE" is $true.

    To test:


    which will always evaluate to $true.

  • I always rather use Exchange cmdlets for setting these attributes

    set-mailbox accountname -HiddenFromAddressListsEnabled $true

  • Get-ADUser -filter * -searchbase "OU=()Disabled,OU=2,DC=1,DC=local" | 
    	Set-ADUser -replace @{msExchHideFromAddressLists=$true}

    Did that.

  • Then use Get-Mailbox and pipe the results to Set-Mailbox. Why not use the tools designed to work with the objects you're working with?
