Exchange Server 2010 Group Usage with Windows Powershell

So I have been running some discovery scripts on an M&A and wanted to check DL’s and when they were last used.  Came up with this ..

$days = 90
Set-ADServerSettings -ViewEntireForest:$true
$results = Get-TransportServer | get-messagetrackinglog -eventid expand -resultsize unlimited -start (get-date).addDays(-$days) | sort timestamp -desc
$results.count

IF(![string]::IsNullOrEmpty($results)) {
  $report = @()
  $lists = @()
  $data = $results | group relatedrecipientaddress | sort name
  $lists = get-distributiongroup -resultsize unlimited | Select Alias, primarysmtpaddress, Name, RecipientType, OrganizationalUnit, @{Expression={""};Label="Count"}, @{Expression={""};Label="LastUsed"}
  $lists += Get-DynamicDistributionGroup -ResultSize unlimited | Select Alias, primarysmtpaddress, Name, RecipientType, OrganizationalUnit, @{Expression={""};Label="Count"}, @{Expression={""};Label="LastUsed"}
  $lists = $lists | sort alias
  foreach ($list in $lists) {
    $check = $null
    $check = $data | ?{$_.name -like "$($list.primarySMTPaddress.tostring())"}
    if ($check) {
      $List.Count = $Check.Count
      $List.LastUsed = ($check | select -expand group | select -first 1).TimeStamp
    }
  }
}

$lists | Export-csv GroupsWithUsage.csv -NoTypeInformation -Encoding  Unicode

Enjoy

#Powershell and Get-ExchangeServer

Now that is cool.  Been playing with the cmdlet Get-ExchangeServer.  I wanted to get a group of different server names in one go, without having the run the cmdlet multiple times.

So I thought I would try and chuck an array at Get-ExchangeServer and see what it does?  It only bloody works ;-)

$s=@()
$s +="MyServers*"
$s += "Exch*"
$s | Get-ExchangeServer

Neat trick, and you can also pass arrays in as a script parameter too.  Found this: http://santoshbenjamin.wordpress.com/2008/09/30/powershell-and-arrays-as-named-parameters/

The key for a script or function parameter is [String[]]$Server=”*”

I Like it ALOT!

#MsExchange Versions

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:

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
