Exchange Mailbox Litigation Hold Size Report

Most companies always have some sort of litigation going on, which requires putting users' mailboxes on hold to keep historical data. Sometimes I forget who's on litigation hold, and they stay in that state long after they should be - taking up storage space on Exchange.

I created a little script that will spit out an HTML report of mailboxes with litigation hold enabled and their total size.
This is also useful for when your higher-ups need that info for auditing and such, since it's easy to read in HTML format.

Grab the script from my Google Drive here.

-or-

Copy the following block and save as Litigation-Report.ps1

$style = "<style>BODY{font-family: Arial; font-size: 10pt;}"
$style = $style + "TABLE{border: 1px solid black; border-collapse: collapse;}"
$style = $style + "TH{border: 1px solid black; background: #dddddd; padding: 5px; }"
$style = $style + "TD{border: 1px solid black; padding: 5px; }"
$style = $style + "</style>"

Get-Mailbox -ResultSize Unlimited -Filter {LitigationHoldEnabled -eq $True} | Get-MailboxStatistics | Sort totalitemsize -desc | select displayname, totalitemsize | ConvertTo-HTML -head $style | out-file Litigation_Size.htm


Once you have the script downloaded or copied, fire up the EMS (Exchange Management Shell) and cd to the location where you saved it.

Next, run Litigation-Report.ps1

The script will save the "Litigation_Size.htm" in the same location as the .ps1 file.

Now you have a nice, pretty report...give it your legal department and tell them they're using too much space :)
