Add Your Outlook Contacts to Barracuda Whitelist

These steps will allow you to export your Outlook Contacts to Excel. You can then cleanup the email addresses and add them to your Barracuda Whitelist.

Note: The Export steps will walk you through exporting only the main email Address value for a contact. If you want to gather other addresses, Examples: E-mail 2 Address, E-mail 2 Address, you can repeat the export process to gather these addresses. The E-mail Address Cleanup in Excel is much easier if you are only dealing with a single column of data.
