The Outlook Address Book file, denoted by the .OLK file extension, is a data file utilized by Microsoft Outlook. It serves as the central repository for contact information, acting as a digital address book. OLK files store various details about each contact, including their name, email address, phone numbers, and other relevant data.

OLK files are seamlessly integrated with Outlook’s contact management system. Users can create, edit, and modify contacts directly within the software, with all changes automatically saved to the associated OLK file. Outlook utilizes OLK files to display contact information in its dedicated “Contacts” section, allowing users to easily search, filter, and communicate with their contacts. Additionally, OLK files facilitate the import and export of contact data, enabling users to transfer their contacts between different devices or share them with others.
