# Script  : DiskSpace.ps1 
# Author  : Tom Anderson - http://tomandersonpro.net   
# Date    : 13-03-2013    
# Purpose : This script checks the disk size and free space in Gigabytes for each 
#         : Exchange server in your environment that runs Exchange 2007 or newer   
#         : A report is created and sent out via email to address specified.

#### Set parameters for output filename  
$date = ( get-date ).ToString('yyyyMMdd') 
$file = New-Item -type file "C:\Temp\ExchangeDailyChecksHistory\$date-ExchangeFreeDiskSpace.txt" -Force 
 
#### E-mail variables 
$smtpServer = "EXSVR" 
$recipient = "[email protected]" 
$sender = "[email protected]domain.com" 
$Subject = "Daily Exchange Server disk space report" 
$Body = "Please find report attached." 
 
#### Poll Exchange environment to retrieve any servers newer than 2007  
#### (I used this filter as for some reason an Exchange 2003 box was reporting as being in the environment, despite having been removed some time ago) 
$servers=Get-ExchangeServer |where-object {$_.isExchange2007OrLater -eq $True} 
 
#### Set values for progress counter 
$serverscount = $servers.count;$i=0  
 
#### Loop through each server retrieved 
foreach ($server in $servers) {   
 
#### Get disk space 
'Get Disk Space ' +  $server |out-file $file -append 
get-wmiobject -computer $server -query ` 
"Select * from win32_logicaldisk ` 
where DriveType=3" | sort DeviceId | format-table DeviceId, VolumeName, @{Label="Size in GB"; Expression={[math]::round(($_.Size/1GB),2)}}, @{Label="Free space in GB"; Expression={[math]::round(($_.FreeSpace/1GB),2)}} -auto | out-file $file –append 
} 
 
#### Send message 
Send-MailMessage -From "$sender" -To "$recipient" -Subject "$Subject" -Body "$body" -Attachments "$file" -smtpserver "$smtpServer"
