Problem with Outlook after installing Internet Explorer 7

Last day I needed to install Internet Explorer 7 to test a client’s website in it ( I’m a Firefox fan but it seems I just can’t get rid of IE ). The installation went ok and the testing was completed on time. The problem appeared when I tried to get my hotmail emails through Outlook Express, it gave an ‘authentication failed’ error , it was scary, I though that the hotmail stuff removed the Outlook Express mail retrieval option for their free accounts or, even worse, someone broke in and changed the password. I went stray to www.hotmail.com to see if the password was still valid. Thanks God, it was ok , so I started to google some info about this issue and from website to website I got on Microsoft’s Knowledge Base where after I downloaded and installed their patch, everything was alright again
