What mail is stored and synced on the mobility server?

When data is synced from GW to the sync server, does it get automatically deleted from the sync server after a certain period of time if the mobile user doesn't connect to download it?

 By default when a user is added to datasync, mobility downloads 3 days old emails, 2 weeks old calendar items, all future calendar items, and all personal address books except frequent contacts. If the device never connects to mobility, mail will get expired/deleted after 3 days, calendars will get expired after they are 2 weeks old. At any time, the mobility server will have 3 days old mail and, 2 weeks old calendar entries.
