I am trying to get way from the nightmare of Windows Live Mail 2011, mostly due to two bugs that are still in the latest version of the program.
I'm trying to migrate from WLM2011 to Outlook 2003 and I have run into a brick wall on importing my email accounts. Microsoft has extensive help pages on migrating TO Windows Live Mail, but apparently they do't think anyone would ever want to go FROM Windows Live Mail.
There is a good article at Migrate from Outlook Express or Windows (Live) Mail to Outlook | HowTo-Outlook
which covers migrating the messages and contacts, but no one seems to have found any way to get your account data from WLM into Outlook. WLM will export the account data as iaf files (just like Outlook Express did) but Outlook doesn't recognize the iaf files.
I found a couple of old Outlook help pages that talk about importing IAF files, but the procedure shown does not work because Outlook doesn't ever give you any chance to tell it where to look for the IAF files, it just says "No internet accounts were found to import"
