Run cmdlets from non AD users? Is it possible?

Question

Hello!
I call powershell script from local user and obviously get access error. For example I need to get this info from AD:
(Get-MailBox -database DB2 -resultsize unlimited | Get-MailBoxStatistics | Add-Member -MemberType ScriptProperty -Name TotalItemSizeinGB -Value {$this.totalitemsize.value.ToGB()} -PassThru | measure-object -property TotalItemSizeinGB -sum).Sum
I can use “-credential $Cred” only with Get-Mailbox. What about the others  cmdlets?
Anyway, there is a huge similar cmdlets giving access error if I don’t use AD user with proper permissions.
I need this for monitoring system which works from LocalSystem account.
Could somebody advice please?

Here is how to access Exchange via EWS:
$usermailid='[email protected]'
add-type -path 'C:\Program Files\Microsoft\Exchange\web services\2.2\Microsoft.Exchange.WebServices.dll'
$ews=New-Object Microsoft.Exchange.WebServices.Data.ExchangeService -ArgumentList Exchange2013
$cred=(Get-Credential $usermailid).GetNetworkCredential()
$ews.Credentials=New-Object System.Net.NetworkCredential($cred.UserName, $cred.Password)
$ews.AutodiscoverUrl($usermailid,{$true})
$iv=[Microsoft.Exchange.WebServices.Data.ItemView]100
$results = $ews.FindItems('Inbox',$iv)
$results.Items|
ForEach-Object { $_.Subject }
Any valid user can remote this way.
¯\_(ツ)_/¯
