How to change the SharePoint user display name with PowerShell? Well, You can use Set-SPUser cmdlet. Just provide the account identity, site and the new display name for user user.

Add-PSSnapin Microsoft.SharePoint.PowerShell -ErrorAction SilentlyContinue #User Account to Sync and Site where the account exists $UserAccount="Crescent\alex" $WebURL="https://portal.crescent.com/projects/" #Get the User's Current Display Name and E-mail Get-SPUser -Identity $UserAccount -Web $WebURL | Select DisplayName,Email #Force Sync from Active Directory Set-SPUser -Identity $UserAccount -Web $WebURL -SyncFromAD
