PowerShell script to upload user profile images to Office 365

There are numerous posts out there about how to do this, but thought I’d share my small script which includes the option to have images > 10kb. The script assumes you have a folder with with images on the notation <username>.jpg. It will loop over all images and use the Set-UserPhoto commandlet to upload the image.

The first time you run the script it prompts you for the password for the account you are using and stores it as a secure string in a file to be used on sub-sequent runs or on a schedule. The script will also move images one folder up after processing.

$adminUser = "foo@contoso.onmicrosoft.com"
$localFolderPath = "d:\images\upload" 
$passwordFile = "$PSScriptRoot\userphoto-password.txt"

if(![System.IO.File]::Exists($passwordFile)){
    read-host -prompt "Type the password for $adminUser to be used (will be saved encrypted)" -assecurestring | convertfrom-securestring | out-file $passwordFile
}

$password = cat $passwordFile | convertto-securestring
$MSOLCred = new-object -typename System.Management.Automation.PSCredential `
         -argumentlist $adminUser, $password

$ExOLSession = New-PSSession -Credential $MSOLCred -authentication Basic -Configurationname Microsoft.Exchange -ConnectionURI https://outlook.office365.com/powershell-liveid/?proxyMethod=RPS -allowredirection

#load Exchange Online Management cmdlets
Import-PSSession $ExOLSession -AllowClobber

$files = ([System.IO.DirectoryInfo] (Get-Item $localFolderPath)).GetFiles() |  ForEach-Object {
    if(([IO.Path]::GetExtension($_.FullName)) -eq ".jpg") {    
        $username = [IO.Path]::GetFileNameWithoutExtension($_.FullName);    
        $userPhoto = ([Byte[]] $(Get-Content -Path $_.FullName -Encoding Byte -ReadCount 0))
        Set-UserPhoto -Identity $username -PictureData $userPhoto -Confirm:$False
        
        #move files one folder up after processing
        $destinationFolder = Split-Path -Parent $_.Directory.FullName
        move-item $_.FullName $destinationFolder
    }
}
#unload session
Remove-PSSession $ExOLSession
