How to Clean up a Mailbox or Clean up the Dumpster using Discovery Search in Exchange 2010

Updated – Supports Exchange 2010/2013 and Exchange 2016

Lets say I want to Clean up a Users mailbox completely to have a fresh Start.

We can use Discovery Search to do this task

First Assign the Permissions which is required to use discovery Search – Refer Below link


I just Created a Test user with Few mails and Few Items in his dumpster


Get-MailboxFolderStatistics -Identity "User2" -FolderScope RecoverableItems | Format-Table Name,FolderPath,ItemsInFolder,FolderAndSubfolderSize


Now am doing a search query with a wildcard to query everything and deleting it completely including the archive mailbox

Get-mailbox "User1"| search-mailbox –searchquery "Subject:'*'" –DeleteContent

Caution : Its going to Clean up the Archive Mailbox as well

Use this command for not to include archive

Get-mailbox "User1"| search-mailbox –searchquery "Subject:'*'" –DeleteContent -<em>DoNotIncludeArchive


Use this command to delete Dumpster alone

Get-mailbox "User1"| search-mailbox –searchquery "Subject:'*'" –DeleteContent -<em>SearchDumpsterOnly</em>


Now mailbox is cleaned up completely including the dumpster

Get-MailboxFolderStatistics -Identity "user1" -FolderScope RecoverableItems | Format-Table Name,FolderPath,ItemsInFolder,FolderAndSubfolderSize
