Getting Database counts per Exchange Server via PowerShell

Was recently asked to generate a report of the total count of items per Exchange database per server. This one-liner (broken up for readability), takes care of it.

Get-MailboxServer | Get-MailboxStatistics | `
Sort-Object DatabaseName | `
Select DatabaseName, ItemCount | `
Group-Object -Property DatabaseName | `
Foreach {            
    $items = ($_.Group | Measure-Object -Property ItemCount -sum).Sum            
    "{0}`t{1:N0}" -f $_.Name,$items             
}

This will generate something like the following:

Exchange01-DB01	1,372,127
Exchange01-DB02	1,522,356
Exchange01-DB03	1,406,486
Exchange01-DB04	1,345,962
Exchange01-DB05	1,330,690
Exchange01-DB06	1,392,853
Exchange01-DB07	1,318,130
.....	.....

Enjoy!

Managing Proxy Settings with PowerShell

I find myself changing proxy settings often on my laptop between various environments (Home, Production and Test). Generally this is no big deal. But today, I found myself switching multiple times as I was testing ISA and realized that PowerShell can easily take care of this.

At some point, I will wrap this into a GUI but for now, here is the script.

Note: I am using Jeff Hick's Test-RegistryItem.Enjoy!

function Set-Proxy {          
  [cmdletbinding()]          
  Param (          
      [Parameter(Position=0,Mandatory=$True,          
       HelpMessage="Enter either `"Home`", `"Production`" or `"Test`".")]          
      [ValidateNotNullOrEmpty()]          
      [ValidateSet("Home", "Production", "Test")]          
      [String]$Location          
  )           
            
  $path = "HKCU:\Software\Microsoft\Windows\CurrentVersion\Internet Settings"          
  $url  = "http://autoconf.FatBeard.com/proxy.pac"          
            
  switch ($location)          
  {          
      "Home" {           
          Set-ItemProperty -Path $path -Name ProxyEnable -Value 0          
          if (Test-RegistryItem -Path $path -Property ProxyServer) {          
              Remove-ItemProperty -Path $path -Name ProxyServer          
          }          
          if (Test-RegistryItem -Path $path -Property AutoConfigURL) {          
              Remove-ItemProperty -Path $path -Name AutoConfigURL          
          }          
      }          
      "Production" {          
          Set-ItemProperty -Path $path -Name ProxyEnable -Value 0          
          Set-ItemProperty -Path $path -Name AutoConfigURL -Value $url          
      }          
      "Test" {          
          Set-ItemProperty -Path $path -Name ProxyEnable -Value 1          
          Set-ItemProperty -Path $path -Name ProxyServer -Value "TestProxy-vt01:8080"          
          if (Test-RegistryItem -Path $path -Property AutoConfigURL) {          
              Remove-ItemProperty -Path $path -Name AutoConfigURL          
          }          
      }           
  }          
}

Enjoy!
