Opening IAF files

Did your computer fail to open an IAF file? We explain what IAF files are and recommend software that we know can open or convert your IAF files.

What is an IAF file?

Files that contain the .iaf file extension are most commonly used by the Microsoft Outlook email and personal information management software application. Microsoft Outlook is a part of the Microsoft Office Suite.

The IAF files that are used by Microsoft Outlook are used to export the Outlook settings from one computer to another. While newer versions of Outlook no longer create files in the IAF format, they can still import the IAF files in order to import user's Outlook settings.

The .iaf file extension is also used by the Windows Live Mail Internet email service. These files contain the contacts database of a user's email account.
