What data is exported?

  • When Outlook exports email, contacts, and calendar info to a .pst, it makes a copy of the information. Nothing leaves Outlook. You’ll still see and have access to your email, contacts, and calendar in Outlook.
  • When Outlook exports emails, it includes any attachments to the emails.
  • Outlook does not export meta-data such as folder properties (views, permissions, and AutoArchive settings), message rules, and blocked senders lists.

Important: If you’re using Cached Exchange Mode, Outlook will only export the items in your current cache. By default, your cache contains items from the past 12 months. To export more than the past 12 months of data, turn off Cached Exchange Mode first.
