File type specification:

Internet related file type icon Internet related file type

The VFB file extension is also related to Microsoft Outlook, a personal information manager, which is part of Microsoft Office, developed by Microsoft Corporation.

This type of .vfb files are used for Free/Busy feature of Microsoft Outlook. Internet Free/Busy (IFB) is a feature of Microsoft Outlook that allows you to see when others are free or busy so that you can efficiently schedule meetings. Outlook users have the option to publish their free/busy information to a user-specified Uniform Resource Locator (URL) file server. You can share this URL file server with all users or limit it to a specific set of users.

An Internet Engineering Task Force (IETF) standard called iCal, is the basis for IFB. IFB uses a part of the iCal standard called iCalendar, an emerging standard for the format and storage of schedule information. iCalendar defines a structure for representing free/busy information in a standardized way.
