I'm sorry I know this thread is really old but it was one of the first results that came up when searching Google. Unfortunately Irene that is not how you backup up email account settings in Outlook. It will work for backing up the email, calendar, and contact data but the accounts themselves will not be exported. Microsoft even admits that this is not possible. If you look at the link posted earlier at: You cannot import or export e-mail accounts with .IAF files in Outlook
you will notice they are talking about importing
from other programs into outlook, not exporting
from outlook. They removed the ability to export from any version of Outlook newer than Outlook 2000
There is a solution / workaround that involves exporting a registry key. It is posted on these forums here: How to backup Outlook profiles
Again, sorry to resurrect such an old thread but I wanted to help other people who got here from Google like I did.
