When I try to login to https://skydrive.live.com/ using Internet Explorer 9 I get into a redirect loop where I'm redirected to https://login.live.com/, then back to https://skydrive.live.com/, then to https://login.live.com/ and so on until the loop is detected and the Windows Live login fails.
However, if I start Internet Explorer 9 using the -extoff (no add-ons) command line option I'm again able to login to Skydrive. Turning off all add-ons using the Manage add-ons dialog box has no effect and the login process still loops.
I have tried to delete all cookies and temporary internet files and uninstalled the Windows Live Login Assistant but this hasn't solved my problem. Also, FireFox does not have any problems performing the login.
I have used Fiddler to look at the traffic and I have noticed that after the login site redirects to skydrive the cookies sent to the skydrive site are different:
Using IE9 wihout add-ons cookies like RPSTAuth, MSPAuth, MSPProf and MSNPPAuth are set and login is succesful.
Using IE9 normally cookies like wls, wlv, wlp, BP, LN, MUID, drua and HIC are set and login gets into a redirect loop.
I'm on a corporate network with a proxy server that requires authentication making it hard for me to attempt the login using a different user on the computer.
What is going on with the -extoff command line option as opposed to disabling all add-ons in the dialog box and what can I do to be able to login to Skydrive without having to use that option?
