.OLK14TASK File Extension

File used by Microsoft Outlook for Mac, a calendar and email application that replaced Microsoft Entourage; contains a task, or "to-do," that was created in the program; used for marking messages that are flagged for follow up.

OLK14TASK files are saved automatically by the software when a new task is created. They are not manually opened or saved by the user since the software interface provides access to the tasks.
