#This is an example of doing exchange operations in parallel in runspaces.
#When Exchange PowerShell Module Connects, it saves token info in a global .NET object and then asks an API to generate a PowerShell
#Module when it downloads. That PowerShell module has the path for the key built-in, so all you have to do
#Is load the specified module into each runspace.

<#[
.SYNOPSIS
	Parses Exchange log files and returns records in descending date order.

.DESCRIPTION
	Exchange logs store their column names in a '#Fields:' comment line. This
	script reads that header, parses every data row, and sorts all records from
	newest to oldest using the 'date-time' column.
