SUMMARY
This article explains how Mailbox Manager uses the System Cleanup folder, and the way that deleted item retention interacts with the System Cleanup folder.



MORE INFORMATION
When you set the deletion mode to Move to System Cleanup Folders, a replica of the existing mailbox folder hierarchy is created in a top-level folder called the System Cleanup folder. Targeted messages are moved to the corresponding folder in the System Cleanup folder, which retains the folder location of a given message. Typically, the System Cleanup folder is created on the client when Mailbox Manager is configured to use the System Cleanup folder. The System Cleanup folder temporarily holds deleted items until you permanently remove the deleted items.

If a user deletes a message from the System Cleanup folder, it is moved to the Deleted Items folder. If a message is deleted from the Deleted Items folder, you may be able to recover the message, depending on the deleted item retention time.

If items are deleted from the System Cleanup folder based on the policies for folder age limits on System Cleanup folders, these items are deleted permanently from the user's mailbox and cannot be recovered.

If no items are in the System Cleanup folder the next time the System Cleanup process runs, the System Cleanup folder is moved from the client.
