Creating a naming convention for local user profile name when singing in with a M365 user

Question

Hello,

as far as I'm aware, the name used for the local user profile when logging in to an Entra ID joined device for the first time is the first 20 letters of the M365 display name with special characters and spaces removed. We would like to keep the display names as it, but instead use an abbreviation for the name of the local user profile.

Example: When the display name in M365 is "Alex Wilber | Company A" we would like to have "AWI" as the name of the local user profile instead of "AlexWilberCompanyA".

We also would like this to be an automatic process more or less. Is there any reasonable way to archive this?

Hi @PKU

Thank you for posting this in Microsoft Q&A.

I understand you want to Create a naming convention for local user profile name when singing in with a M365 user.

You can use PowerShell to automate this process.

Install-Module -Name AzureAD
Import-Module -Name AzureAD

Connect-AzureAD
$userid = "replace user object Id"
$userdetails = Get-AzureADUser -ObjectId $userid 
$displayName = $userid.displayname
$firstName = ($displayName -split '\s+')[0]
$lastName = ($displayName -split '\s+')[1]
$companyName = ($displayName -split '\s+\|\s+')[1]
$abbreviation = $firstName.Substring(0,1) + $lastName.Substring(0,1) + $companyName.Substring(0,1)
Set-AzureADUser -ObjectId $userid  -DisplayName $abbreviation

To update bulk users, create a CSV file as userIDs.csv with UserID

$userIDs = Import-Csv -Path "userIDs.csv" | Select-Object -ExpandProperty UserID

foreach ($userID in $userIDs) {
    # Retrieve user details
    $userDetails = Get-AzureADUser -ObjectId $userID
    
    $displayName = $userDetails.DisplayName
    $firstName = ($displayName -split '\s+')[0]
    $lastName = ($displayName -split '\s+')[1]
    $companyName = ($displayName -split '\s+\|\s+')[1]
    
    $abbreviation = $firstName.Substring(0,1) + $lastName.Substring(0,1) + $companyName.Substring(0,1)
    # Set new DisplayName
    Set-AzureADUser -ObjectId $userID -DisplayName $abbreviation
}

Hope this helps. Do let us know if you any further queries.

Thanks,
