Exchange power shell 2010 - emptying deleted items folder

is there a way or a combination of cmdlets one could use to empty a users deleted folder ?

I have heard of search-mailbox but not seeing much in the help on how to use it.

Search-mailbox can't really be used because you can't use it to return all the results of a specific mailbox folder. Rather, to clear out the deleted Items folder for all or specific users, you would want to make use of the retention policies. Create a retention policy for the Deleted Items folder, set it for a week or a day or however long, and apply it to the user. There is a default retention policy in place that clears the deleted items folder after 30 days, but you have to make sure it's applied and the emails in the deleted items folder are tagged with that policy.

Here you go:

Search-mailbox -identity <alias> -SearchDumpsterOnly -DeleteContent

yes I found that and did not work because that is deleting the dumpster which is where it goes after a user empties the deleted folder.  that way when they say oops there is still time to recover it.

Thanks for the solution acbrown.  I have applied the retention policy and found out that it does not apply the policy according to the mailbox processing which is set in my case to 24 hours.  I have run Start-ManagedFolderAssistant -Identity “Administrator” to force but the policy still has not applied.  does it still take some time even after the force ?

Existing emails have to be "tagged" with the policy in order to get removed by it. You can do this by opening the mailbox is outlook and right-clicking the folder, then selecting the option to apply the existing retention policy (I think. I don't have a valid test in front of me at the moment. Working off memory).
