Exchange Server 2007’s Managed Folders come in two flavors: 1) Managed Default Folders 2) Managed Custom Folders. Default folders are the ones created by default in user mailboxes, such as Inbox, Sent Items, and Deleted Items. Custom Folders are the result of a much-requested feature by Exchange folks over the years: Can I create a folder called “Project Blah” in all mailboxes?
Exchange setup creates a set of Managed Default Folders for each type of default folder e.g. Deleted Items. These are visible in Organization Configuration | Mailbox | Managed Default Folders tab, or by using the Get-ManagedFolder cmdlet.
To apply message retention settings for items in a managed folder, you must create Managed Content Settings for it. For example, you can create a Managed Content Setting to retain items in the Deleted Items folder for 30 days, and permanently delete items older than 30 days.
Next, you want to create another setting for your executives with a higher retention period of 300 days for the Deleted Items folder. If you try to create another Managed Content Settings for the same Default Managed Folder, you get the following error.
Managed Folders and Managed Content Settings
If Exchange allows you to associate only one Managed Content Settings with one Managed Folder, I’ve often wondered, why not allow specifying content retention settings in the Properties of that Managed Folder? Why have a Managed Folder AND a Managed Content Settings for that folder as separate objects?
This is to allow different Managed Content Settings for different types of items in a Managed Folder. For example, for the Deleted Items folder, you can create a Managed Content Setting to permanently delete messages after 30 days, but retain other types of items such as faxes or Contacts for a little longer, let’s say 60 days.
Note: You cannot change the Message Type selected in Managed Content Settings after it is created. To select a different Message Type, you must delete the Managed Content Settings object and recreate it with the Message Type you want.
Create another Managed Default Folder
To create a new Managed Content Settings for a default folder, Deleted Items in this case, we’ll need to create another Managed Default Folder.
- In the Exchange console, select Organization Configuration | Mailbox | Managed Default Folders.
- In the Actions pane, click the New Managed Default Folder link.
- In the New Managed Default Folder page, enter a name for the new default folder instance.
Note, unlike Managed Custom Folders, default folders such as Deleted Items, Inbox, Sent Items, Drafts, etc. already exist in a mailbox. What we’re doing here is simply creating an instance or representation of a default folder as an object in Active Directory (where Exchange stores its configuration) so we can create one or more Managed Content Settings associated with it. The default older can then be added to a Managed Folder Mailbox Policy and the policy applied to mailboxes.
- Default Folder Type: Select the correct default folder type. For this example we select Deleted Items.
- Display the following comment when the folder is viewed in Outlook: [Optional] Type a comment in this box. The comment will be displayed in Outlook 2007 when the user selects this folder.
- On the Completion page, click New | click Finish.
Now you have another instance of the Deleted Items folder. You can create Managed Content Settings for it, and add it to a Managed Folder Mailbox Policy.
