Exchange 2010 – Locating Disconnected Mailboxes

Here is a quick Powershell function to make finding disconnected mailboxes easier.

Save this as Get-DisconnectedMailbox.ps1:

function Get-DisconnectedMailbox {
    [CmdletBinding()]
    param(
        [Parameter(Position=0, Mandatory=$false)]
        [System.String]
        $Name = '*'
    )

    $mailboxes = Get-MailboxServer
    $mailboxes | %{
        $disconn = Get-Mailboxstatistics -Server $_.name | ?{ $_.DisconnectDate -ne $null }
        $disconn | ?{$_.displayname -like $Name} |
            Select DisplayName,
            @{n="StoreMailboxIdentity";e={$_.MailboxGuid}},
            Database
    }
}

Open the Powershell console, and dot source the function, assuming PS1 is stored in c:\scripts

cd c:\scripts
. .\Get-DisconnectedMailbox.ps1
Get-DisconnectedMailbox mailserver1.contoso.com
