I am migrating to exchange 2013 from ex2007sp3.  Prior to moving mailboxes to the ex13 server, I have been tasked with deleting messages from the Exch2007sp3 database older than 90 days. 

This is my pshell cmd so far:

Get-Mailbox -Database "private information store" | Export-Mailbox -EndDate 1/1/2015 -ExcludeFolders "\Calendar" -DeleteContent -BadItemLimit 100

I plan to change the Delete Item Retention to 0 days so that the messages are truly gone.

Does anyone have a better suggestion?

 Thanks

In Exchange 2007, If you want to recover deleted mailboxes from exchange 2013, By default deleted email items is retained for x days and deleted the mailboxes for 90 days and settings are set on database level. More information, please refer to the links:

Also, could you please brief here about your retention policy ?

Moreover, you could try automated exchange mailbox recovery tool ( http://www.exchangemailboxrecovery.co.uk/ )that allow restore permanently deleted mailboxes from exchange server. You can easily restore all mailboxes database in few seconds.

Hi,

If the items which are older than 90 days have been deleted for all mailboxes in Exchange 2007, we can directly move the mailbox to Exchange 2013. Generally, the deleted items are retained in the mailbox database until the deleted items retention period expires, which is 14 days by default. And the deleted items would not be moved to Exchange 2013 if you migrate the mailbox from Exchange 2007 to Exchange 2013.

If you still want to change the set the Delete Items Retention for a mailbox in Exchange 2007, we can run:

Set-MailboxDatabase <database_name> -DeletedItemRetention 0.00:00:00

This is the cmd I am running to delete messages from a specific mail database :

Get-Mailbox -Database "private information store" | Export-Mailbox -ExcludeFolders "\Calendar" -EndDate 1/12/2015 -DeleteContent

However, when I run the cmd it just goes back to the prompt.  Heres the log entry:

The mail server is in a separate domain from where the user accounts reside.  I am trying to run this from the mail server.  The account I am logged in with has full rights on all mailboxes.
