I running a simple code:Set-MailboxCalendarConfiguration on about 700 users but I keep getting The I / O operation was aborted error.

I thought it was a session issue so I added to code $EOLSession.state -eq 'Broken' -or !$EOLSession

That did not work. So I googled more and i found that it might be related to WinRM service so I added more code. That also did not work ...I can't find anything else. Can someone help me please?

my code is below:

foreach ($user in $users) {
try
{
Function Reconnect-ExchangeOnline 
    {
if ($EOLSession.state -eq 'Broken' -or !$EOLSession) 
    {
    Disconnect-ExchangeOnline; Start-Sleep -Seconds 3; Connect-ExchangeOnline
    }    
}
$serviceWinRM = get-service WinRM
if ( $serviceWinRM.Status -eq "Stopped")
{ 
start-service WinRM;Start-Sleep -Seconds 4
}
    Set-MailboxCalendarConfiguration -identity $user.userprincipalname -WorkDays Weekdays  -WeekStartDay "Monday"
}
catch 
    {
    $Error[0].Exception.GetType().FullName
    Connect-ExchangeOnline -UserPrincipalName xxxxxx
    }}
