Overview

Microsoft volunteered to start OLK. It stands as an abbreviation, “Outlook Address Book.” The Mac Outlook email program supports the OLK file extension, therefore enabling effective storage of contact data for both personal and corporate use. It holds names, addresses, phone numbers, email addresses, and a great lot more. The letter olk denotes the file’s extending denotation. To utilize the extension properly, one must be aware of the several variants or forms of it.
