  Begin {
    Write-Host "Connecting to VMware environment [$VMServer]..."

#-----------------------------------------------------------[Execution]------------------------------------------------------------

$Server = Read-Host 'Specify the vCenter Server or ESXi Host to connect to (IP or FQDN)?'
Connect-VMwareServer -VMServer $Server
#Script Execution goes here

The $ErrorActionPreference = 'SilentlyContinue' is stopping the incorrect user/pass exception from being caught.
I had to append '-ErrorAction Stop' onto Connect-VIServer to make it work.

Could be my version 3 of powershell?
