PowerShell - Export Mailbox Statistics to HTML Report - powershell

Question

I'm trying to generate a general system report that pulls basic statistics for network hosts. My script works as expected up until the "o365ExchConn" function, whereby it pipes all of the "Import-Pssession" output into the variable that's used to generate the HTML fragment at the end of the script.
How do I exclude this output? I just require the statistics specified in the array within the function. (i.e. Displayname, TotalItemsize & TotalItemCount).
$computername = Read-Host -Prompt "Enter Hostname"
$path = Read-Host -Prompt "Enter path for HTML report output (e.g. C:\Temp)"
$date = Get-Date
function Get-CSInfo {
param($computername)
$os = Get-WmiObject -Class Win32_OperatingSystem -ComputerName $computername
$cs = Get-WmiObject -Class Win32_ComputerSystem -ComputerName $computername
$props = #{‘Hostname’=$computername
‘OS Version’=$os.version
‘OS Build’=$os.buildnumber
‘Service Pack’=$os.sevicepackmajorversion;

Write-Output $obj

function Get-RamInfo {
$os = Get-WmiObject -class Win32_OperatingSystem -ComputerName $ComputerName
$cs = Get-WmiObject -class Win32_ComputerSystem -ComputerName $ComputerName
$props = #{'RAM (GB) - Total Available'="{0:N2}" -f ($cs.totalphysicalmemory / 1GB);

There are multiple ways in PowerShell to prevent cmdlets from outputting text where it's not desired.
