Deleting a Specific Email from Entire Organization in Exchange 2010

Updated – Supports Exchange 2010/2013/2016 and Office365

There are many scenarios where we need to get rid of some Emails from the whole server

1. Virus

2.Confidential Email sent wrongly – Got to remove it

3. Need to remove a Email with Specific subject from all the mailboxes

Exchange 2010 has Good features on Searching it and Remove it .

So Will Learn how to do that.

For a User to Execute this commands , he needs specific permissions like he should be a member of Discovery Management role and he should be member of Mailbox Import Export

By Default, Administrator is not a member these roles

Use Exchange Management Shell

Replace the User Name with the Person whom you want to give access to Search and delete

Add-RoleGroupMember "Discovery Management" -Member "User Name"


You can use GUI or Shell, Adding the Discovery Management Role via GUI is much easier.


Login with the Exchange Control Panel URL below –


Login with Admin Credentials –


Double Click on Discovery Management and Add Administrator as a member of Discovery Management and Save it




To Add a User in Mailbox Import Export Role – Run in Exchange Management Shell

New-Managementroleassignment –Role "Mailbox Import Export" –User "Administrator"



Close and Reopen the Exchange Mangement Shell – so that the new commands will start working


Now Before Deleting in Bulk , We can use a log only switch to verify how many Mails we are going to delete

and to verify the we are going to delete the right one

Get-mailbox | search-mailbox –searchquery "Subject:'virus'" –Logonly –Targetmailbox administrator –Targetfolder Inbox

Now this will show how many mailboxes have this content


A mail will be generated to Administrators inbox with Item Count As shown below —



Now we will go ahead and delete it

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


Before — From All the Mailboxes


Now its gone from All the mailboxes
