#MsExchange Versions

#IAMMEC

So if you want to find out the version of Exchange you are running you can always run:

Get-ExchangeServer | Select Name, ServerRole, Edition, AdminDisplayVersion

Now this is cool, but it only shows the major version and not the CU.

You can find exchange build information from two main places:

• http://social.technet.microsoft.com/wiki/contents/articles/240.exchange-server-and-update-rollups-build-numbers.aspx
• http://technet.microsoft.com/library/hh135098.aspx

I have dropped the information into a CSV file [ExchangeBuilds].   I found that updating a CSV file with new builds was easier than editing code all the time.

Now code below to create a summary matrix.  Enjoy

#Import the csv and covert to a hash table
$ExchangeBuilds = import-csv .\ExchangeBuilds.csv
$BuildMatrix = @{}
ForEach($Item in $ExchangeBuilds){
  $BuildMatrix.Add($item.Build, $item.version)
}

#Get exchange servers
Get-ExchangeServer | Select Name, ServerRole, Edition, AdminDisplayVersion

#Loop the servers to create the matrix
$matrix =@()
$ExchangeServers = Get-ExchangeServer | Sort Name
ForEach($Item in $ExchangeServers){
  $tmpServer = $item.Name + "." + $item.domain
  Write-Host $tmpServer 
  $tmpMatrix = "" | Select Name, Roles, Edition, FileVersion,UpdateRollup
  $tmpMatrix.Name = $tmpServer 
  $tmpMatrix.Roles = $Item.ServerRole
  $tmpMatrix.Edition = $Item.Edition

  Switch($item.AdminDisplayVersion.Major){
     6 {$key="SOFTWARE\Microsoft\Exchange\Setup"}
     8 {$key="SOFTWARE\Microsoft\Exchange\Setup"}
    14 {$Key="SOFTWARE\Microsoft\ExchangeServer\v14\Setup"}
  }

  #Find the exchange binary path
  $type = [Microsoft.Win32.RegistryHive]::LocalMachine
  $regKey = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($type, $tmpServer )
  $regKey = $regKey.OpenSubKey($key)

  #work out the file we need to use
  Switch($item.AdminDisplayVersion.Major){
     6      {$tmpPath = $regKey.GetValue("Services");      $tmpFile = "mad.exe";    $tmpPath += "\bin\"}
    Default {$tmpPath = $regKey.GetValue("MsiInstallPath");$tmpFile = "ExSetup.exe";$tmpPath += "bin\"}
  }

  #Get the file verision of mad.exe or exsetup.exe
  $tmpPath = $tmpPath.replace(":", "$")
  $tmpunc  = "\\" + $tmpServer + "\" + $tmpPath + $tmpFile

  IF (test-path $tmpunc){
    $tmpVer = (dir "$tmpunc").VersionInfo.FileVersion
    $tmpMatrix.FileVersion = $tmpVer
    $tmpMatrix.UpdateRollup = $BuildMatrix.$tmpver
  }
  $Matrix += $tmpMatrix
}
$Matrix
