A company has elected to automate the deletion of messages within the “Deleted Items” folders based on a retention period of their choice. After the retention period for a specific message(s) with the “Deleted Items” folder, the message will be permanently deleted from that folder. However this will not apply to the Mailbox Database “Deleted Item Retention period currently enforced and users will still be able to perform the “recover deleted items” function from the client.
You can implement MRM (Message Records Management) within the organization to apply messaging policies in various scenarios. You can create managed custom folders in user mailboxes and apply MRM policies to these managed custom folders and also the default folder. You can then configure content settings for both the custom and the default e-mail folders
