Azure – Looping Get-MgUser is doubling results

I have a .TXT of unique DisplayNames (a total of 9). I’m simply populating an array and looping Get-MgUser through it. It returns all each twice.

#Display names list path
    $DnPath = "C:dirnamefilname.txt"
    
#Display names array
    $DnArr = get-content -path $DnPath
    
        
$DnArr | Foreach-Object { 
    Get-Mguser -search displayname:$_ -ConsistencyLevel eventual -Property id | Select-Object -Property id
    
    }

This results in (every ID is twice)

    To fetch the IDs of the users by passing the text file, modify the script like below:

    $DnPath = "C:dirnamefilename.txt"
$DnArr = Get-Content -Path $DnPath
$UniqueUserIds = @()

foreach ($displayName in $DnArr) {
    # Get user ID using the display name
    $user = Get-MgUser -Filter "displayName eq '$displayName'" -Property id

    if ($user) {
        $UniqueUserIds += $user.Id
    }
}
$UniqueUserIds = $UniqueUserIds | Select-Object -Unique
$UniqueUserIds

    My text files looks like below:

    Instead of:

    $DnArr = get-content -path $DnPath

    Try:

    $DnArr = get-content -path $DnPath | Select-Object -Unique

    Example

    Consider a file named c:tempfilename.txt with the following content:

    John
Mary
Peter
Alice
Alice
Peter
John
Mary

    Running the following Powershell script:

    $DnPath = "c:tempfilename.txt"

$DnArr = get-content -path $DnPath | Select-Object -Unique

$DnArr

    Output is:

    John
Mary
Peter
Alice

    It would be better to use -Filter instead of -Search. When using -Search, the input string you provide after displayName is split up into parts by spaces, different casing, or character types (numbers and special characters) and it will return all users where displayName contains the current string.

    $DnArr | Foreach-Object { 
  Get-Mguser -Filter "displayname eq '$_'" -ConsistencyLevel eventual -Property id | Select-Object -Property id
}

    With -Filter only user(s) with exact displayName will be returned.
