Migrate Office365 Photos to AD

Many of my customers have Office365 and have been using Skype for Business for sometime now. It is likely that your organization users have uploaded their profile picture. Now only if there was a way to sync those pictures back to your AD – so it looks neat & nice. There is a way!

#MigrateOffice365PhotosToAD.ps1

function Get-Office365Photo($EmailAddress,$Credential) {
    $wc = New-Object System.Net.WebClient
    $wc.credentials = $Credential
    # Build the URL that'll return the jpeg of the user's photo
    $url = "https://outlook.office365.com/ews/exchange.asmx/s/GetUserPhoto?email=$EmailAddress&size=HR96x96"
    # Build a path to export it to (.\[email protected])
    $outPath = "$pwd\$EmailAddress.jpg"
    try { 
        # Download the image and save it to the current directory
        $wc.DownloadFile($url,$outPath)
        return $outPath
    } catch { throw $_ }
}

function Upload-ADPhoto($Username,$FilePath) {
    # Import the photo into a variable as a byte array
    $photo = [byte[]](Get-Content $FilePath -Encoding byte)
    # Replace the current value of thumbnailPhoto with the byte array from above
    Set-ADUser $Username -Replace @{ThumbnailPhoto=$photo}
}

# Get the credential to allow us to download the images
$Cred = Get-Credential -Message "Please enter your Office 365 Credentials"

# Get every mail-enabled AD user
$users = Get-ADUser -ldapfilter '(mail=*)' -properties mail

# For each of the mail-enabled users...
foreach ($user in $users) {
    try {
        # Download the photo
        $photoPath = Get-Office365Photo -EmailAddress $user.mail -Credential $Cred
        # Upload the photo
        Upload-ADPhoto -Username $user -FilePath $photoPath
    } catch {
        Write-Warning "Unable to update image for $($user.mail)"
    }
}
