Our users all have a folder created in their Mailbox for message organization and retention (done by the previous admin). When our messaging system was Exchange 2003, we were able to create (add) an additional folder in our mailbox manager settings to apply a retention to this folder. Since this is not a default Exchange folder, how can I apply retention policy to this folder in Exchange 2007? Do we have to create this as a Managed Default Folder so that a folder content setting can be created and added to the mailbox policy? If so, if we create a new Default Folder, will this appear in the users mailbox? A folder of this name already exists, we just need to be able to manage the retention of items for this extra folder.
