How to open OLK file?

The first thing you should do is just "doubleclick" on the OLK file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.

Step 1. Install Microsoft Outlook

If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support OLK files.

Programs to open OLK file

Remember to download programs supporting OLK files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Microsoft Outlook with OLK files

If, despite the installed application, the OLK file does not start in the Microsoft Outlook application, you must create a file association. It is most convenient to call the context menu with the right mouse button and select Properties. The displayed window will contain information about the program that supports this type of file. Changes can be made using the "Change" button. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the OLK file with the Microsoft Outlook program.

Step 3. Update Microsoft Outlook to the latest version

If, despite the association of the Microsoft Outlook program with the Outlook Address Book Format file, the file still does not open, check the program version and possibly update it to the newest version. This can be done using the application (if it provides such options) or from the Microsoft Corporation website and install the latest version.

Step 4. Check for the following problems with the OLK file

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The OLK file may be unusually small compared to the original file. Usually this applies to OLK files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The computer may have fallen victim to a computer virus or hacker. Perform a virus scan using available and up-to-date anti-virus software. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the OLK file that we want to open. As a result of the scan, sometimes it is not possible to recover OLK files, which are deleted if there is a backup of this file, then after restoring it, it must also be scanned.
Older version of OLK file may not always be supported by the latest software version. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. Depending on the type of file, it is necessary to repair it accordingly. Some programs offer the ability to automatically repair OLK file corruption. The easiest way to restore the file is from a backup or by contacting Microsoft, but this one can be expensive. Not all damage can be reversed.
The program can also signal the fact of encryption. The encrypted file OLK except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
Some of the system directories are excluded from modification. These directories are write-protected to them and it's very hard to fix this problem. It is best to move OLK to a different directory.
This problem usually affects more complex files. Some file types can only be opened in one program at a time. Just close unnecessary programs. Sometimes it is necessary to wait a while before referencing the OLK file again. Some anti-virus or backup software may occupy the OLK file for a certain period of time. If nothing helps, please reset the device.
