What is a .OLK file?

The .OLK file extension is associated with the Outlook Address Book File. This type of file is created by Microsoft Outlook, which is a program used mainly for sending and receiving emails. However, the Outlook Address Book File is specifically used to keep a list of contact information. This list can include details about people and organizations such as their names, phone numbers, addresses, job titles, and the organizations they belong to, among other pieces of contact information. This makes it easier to manage and access contact details when needed, for example, when sending an email or organizing meetings.

To open a .OLK file, you can use Microsoft Outlook 365 or Microsoft Word 365. These are both part of the Microsoft Office 365 suite, which is a collection of productivity and communication applications. If you are using an older version of Outlook, like Outlook 2003, there is a special way to open .OLK files. You can do this by running a command. The command is: Outlook.exe /l olk_filename, where "olk_filename" is the name of your .OLK file. This command tells Outlook to open the specific .OLK file you have mentioned.

Interestingly, .OLK files can also be opened with Microsoft Word 2003. In Word, these files can be used for various tasks, such as creating personalized mass emails or letters through a process called mail merge. This process allows you to use the contact information stored in the .OLK file to automatically fill in the details in a document template.

It's worth noting that in some cases, Outlook contacts might be stored in a different format known as Personal Address Book (.PAB) files. However, the .OLK format serves a similar purpose in storing and organizing contact information for use within Microsoft Outlook and other compatible programs.
