.SYNOPSIS
Test-ExchangeServerHealth.ps1 - Exchange Server Health Check Script.

.DESCRIPTION 
Performs a series of health checks on Exchange servers and DAGs
and outputs the results to screen, and optionally to log file, HTML report,
and HTML email.

Use the ignorelist.txt file to specify any servers, DAGs, or databases you
want the script to ignore (eg test/dev servers).

.OUTPUTS
Results are output to screen, as well as optional log file, HTML report, and HTML email

.PARAMETER Server
Perform a health check of a single server

.PARAMETER ReportMode
Set to $true to generate a HTML report. A default file name is used if none is specified.

.PARAMETER ReportFile
Allows you to specify a different HTML report file name than the default.

.PARAMETER SendEmail
Sends the HTML report via email using the SMTP configuration within the script.

.PARAMETER AlertsOnly
Only sends the email report if at least one error or warning was detected.

.PARAMETER Log
Writes a log file to help with troubleshooting.

.EXAMPLE
.\Test-ExchangeServerHealth.ps1
Checks all servers in the organization and outputs the results to the shell window.

.EXAMPLE
.\Test-ExchangeServerHealth.ps1 -Server HO-EX2010-MB1
Checks the server HO-EX2010-MB1 and outputs the results to the shell window.

.EXAMPLE
.\Test-ExchangeServerHealth.ps1 -ReportMode -SendEmail
Checks all servers in the organization, outputs the results to the shell window, a HTML report, and
emails the HTML report to the address configured in the script.
