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.
The instructions below refer to Outlook 2013 and 2016. Instructions for older version of Outlook are similar, and can be found at https://support.office.com/en-....

Click Browse to select where to save the Outlook Data File (.pst). Type a file name, and then click OK to continue.
We recommend saving this to a memory stick (the files can be quite large) from where you can then import your email, contacts, and calendar to Outlook on a new machine or with a different provider.
