If you're looking to back up your email contacts then you've come to the right place! This guide was written with Outlook 2013 in mind but most versions of Outlook are very similar.

• Click on "File" then "Open and Export" and then "Import/Export" (the "Export" option may be under "Advanced" in some earlier versions)

• Select "Export to a file" and click "Next"

• Select "Comma Separated Values" and click "Next"

• Select the "Contacts" folder (and any other folder you've set up to save contacts) and click "Next"

• Choose a name for the file and where you would like it saved and click "Next"

• The last page is just for confirmation. Once you're happy with everything click "Finish"

Most email clients will have an option to import contacts and the .csv file that you've just created is the preferred method of doing this.
