Internet Explorer 7 - auto complete on email?

I had the same problem and have solved it but it is not easy to explain. A long detective story here which I am not sure I can adequately summarize here. Do you have Microsoft .NET Framework 2.0 installed? If so that is likely your problem. You likely don't need it and I suggest deleting it using Control Panel, Add or Remove Programs. You could reinstall v. 1.1 as that one is not a problem.

Background: Check the Microsoft IE7 Support website: http://www.microsoft.com/windows/ie/supp...

4th question: "My favorite websites don't load correctly.......", download the tool, and verify that spoofing IE6 allows you to see your Yahoo Mail OK. If so then go to the Microsoft site: http://msdn.microsoft.com/library/defaul...

for further explanation on how User Agent Strings work.

The problem is that .NET 2.0 creates a User Agent String that Yahoo Mail is not recognizing (no doubt they will eventually but who knows when). Yahoo Mail has not configured their servers to accept the combination of IE7 and .NET 2.0

Hope this helps, it did for me, I had exactly the same problem you described (on 2 computers no less) but no longer. I managed to find this out because my 3rd computer had no .NET Framework at all (and never missed not having it as Sun Java is sufficient for me).

Source(s):

Myself, I got no help from AT&T Support, or from Yahoo Mail Support, or Microsoft's Support Center (in India).

Mine did the same thing - but after 12 hours it came back. Keep trying - think yahoo is working on it, or already has it fixed. My address book and autocomplete were both gone. All good now!

I still haven't seen it work correctly with IE 7.
