    Import-PSSession $Session -AllowClobber

if ($Configuration.Steps.AddArchiveToAllMailboxes) {
    $Users = Get-Mailbox -Filter {ArchiveStatus -Eq "None" -AND RecipientTypeDetails -eq "UserMailbox"}
    foreach ($User in $Users) {
        Write-Color 'Enabling archive for user ', $User.UserPrincipalName -Color White, Yellow
        $Output = $User | Enable-Mailbox -Archive
You will need those

Below are 2 modules that I use to Connect to Office 365 and to use colorful output. You still will need standard modules required to connect to Office 365 because PSSharedGoods provides just a wrapper that allow easy connection setup. While you could skip those (and the script that is linked above doesn't require it) I've wrote some simple wrappers that allow me to manage things in easy way, and the way I want it.

Install-Module PSSharedGoods
Install-Module PSWriteColor
