I need a powershell script that will delete a specific e-mail from all mailboxes based on subject. Here is the script I came up with. Get-Mailbox -resultsize unlimited | Export-Mailbox -SubjectKeywords "junk" -Deletecontent -confirm:$falseI have additional requirements I am trying to figure out.I want to delete the message from all mailboxes except for 3 specific users.I also notice that the script will put the deleted message in the "Mailbox Dumpster" in each users mailbox, so the user can recover the message if they want to .Is there a way to purge the message from their dumpster so they cant recover it?

Put some attribute to those three users and then get-mailbox where user doesn't have those attributes.... which will return all the mailboxes which doesn't have those attribute and then disable the dumpster on exchange server.Arun Kumar | MCSE - 2K3 + Messaging | ITIL-F V3

Disable the dumpster on the exchange server? For all users?

The dumpster is disabled on the store level Deleted item retention is disabled for mailbox storeJames Luo TechNet Subscriber Support (http://technet.microsoft.com/en-us/subscriptions/ms788697.aspx) If you have any feedback on our support, please contact tngfb@microsoft.com
