Unable to Retrieve Exchange Online Properties

may be silly, but what version of exchangeOnlineManagement is installed?  be sure it is 3.1.0

We discovered the issue.  Don't issue disconnect-exchangeonline in your script, as it seems to disconnect all exchange sessions inside ARS

Our Library script for EXO now looks as follows, checking for an existing active session.

function onInit($Context) {
    $Context.UseLibraryScript("Library Scripts/UPenn/Include_Debug")
    $Context.UseLibraryScript("Library Scripts/BestPractices-PowerShell")
    
}


function Connect-Exchange {
if((Get-ConnectionInformation).TokenStatus -ne 'Active')
{

      
        $IdleTimeout = $( New-PSSessionOption -IdleTimeout $(New-TimeSpan -Minutes 600000).TotalMinutes)

question: when firing a new workflow that calls the connection function, does it create a new connection to ExOL?  If so, doesn't that also create a new "tmpEXO_" folder in you %temp% folder?  Properly disconnecting from ExOL will remove that "tmpEXO_" folder. I wasn't disconnecting from ExOL for my scripts before and filled up my temp drive.

We were disconnecting after calling an exchange cmdlet under 7.5.3 with the v1/v2 commands. That didn't seem to make a difference with the temp dir.
