Our e-mail server is Exchange 2007. I have configured the Deleted Items to delete every 3 days via the New Managed Default Folders. I configured the Message type for "All Mailbox Content", Length of retention period is set to 3, Retention period starts when item is moved to the folder. The action to be taken is to Permanently Delete.
Next, I created a Managed Folder Mailbox Policy named Mailbox Delete Policy and added the Deleted Items folder to the policy.
After creating the Managed Folder Mailbox Policy, I went to Server Configuration--Selected Mailbox--Selected the properties of the Mailbox server and set a custom schedule from 6--8 pm.
The scheduled task never seems to run. I checked by going to the Deleted Items in Outlook and adding a column for modify date to verify that the e-mails modified datestamp was older than 3 days.
I ran the process manually by using Start--ManagedFolderAssistant -Mailbox 'mailbox name'. The process ran manually on one mailbox. I also tried running the process on multiple mailboxes by using Start-ManagedFolderAssistant. The process did not run on the mailboxes that I reviewed to determine if the process worked.
