HowTo: Remove Users Without Membership

Be sure to check out my Scripting4Crypto initiative. It’s a fun way to get into using cryptocurrencies all while getting your PowerShell needs met.

I recently had a request for a script to remove all user accounts from a ProjectWise datasource if a user account was not a member of any Group. In this post, I want to share what I came up with. Also, I took the idea a little further to include UserLists.

We will be using the following cmdlets to accomplish this task. All of the ProjectWise related cmdlets are available using the PWPS_DAB module. At the time of this post, I am using version Take a look at the help for each of the cmdlets to become familiar with their functionality, available parameters, etc.

  • Get-PWUsersByMatch
  • Get-PWGroupsByUser
  • Get-PWUserListsByUser
  • Remove-PWUserByMatch

As previously stated, the intent of this script is to remove ALL user accounts from a ProjectWise datasource where a user is not a member of either a Group or a UserList.

There are a couple of caveat’s to consider.

  • What if you have a user account(s) you’d like to keep, regardless of membership?
  • What do you do with document ownership when a user account is removed and that user was the owner of a document(s)?

To address these concern above, I am going to create an array containing the name(s) of user accounts to be ignored in this process. I am also, going to specify the ProjectWise administrator as the new owner of any documents a user may be the owner of. This could be any user.

One final note, I am using the Write-Host for demonstration purposes only. I typically would be writing information to a log file.

# User names to be ignored.
[string[]] $pwUsersToSkip = @('pwadmin', 'brian.flaherty')

# The user specified will become the owner of a removed user's documents.
[string] $UserNameForItems = 'pwadmin'

Now, lets get a list of all ProjectWise users.

# Returns all of the users within the ProjectWise datasource.
$pwUsers = Get-PWUsersByMatch
Write-Host "$($pwUsers.Count) user objects returned." -ForegroundColor Green

Next, we will loop through all of the user objects returned. We will determine if each user is a member of a Group and/or a UserList. If they are, we skip them and move on to the next user object.

# Loop through all user objects returned.
foreach($pwUser in $pwUsers) {
    Write-Host "$($pwUser.Name)" -ForegroundColor Green

    # Skip the current user is in the pwUsersToSkip array.
    if( $pwUsersToSkip.Contains($pwUser.Name)){
        Write-Host " - skipping user" -ForegroundColor DarkGreen

    # Get Group membership for the current user.
    $pwGroups = Get-PWGroupsByUser -UserName $pwUser.Name
    if($pwGroups.Count -gt 0){
        Write-Host " - user is a member of a Group(s)." -ForegroundColor DarkGreen
    # Get UserList membership for the current user.
    $pwUserLists = Get-PWUserListsByUser -UserName $pwUser.Name
    if($pwUserLists.Count -gt 0){
        Write-Host " - user is a member of a UserList(s)." -ForegroundColor DarkGreen

    # If not a member of a Group or Userlist, remove the user account.
    if( -not ($pwGroups.Count -gt 0 ) -and -not ($pwUserLists.Count -gt 0)) {
    Write-Host " - removing user" -ForegroundColor Magenta 
    Remove-PWUserByMatch -InputUsers $pwUser -UserNameForItems $UserNameForItems
} # end foreach($pwUser in $pwUsers...

Experiment with it and have fun.
