I had recently signed up for Office Live and associated my passport ID with it as a primary email.
I would log onto my Hotmail account using one instance of my browser and using the second instance I would log on to the Office Live account. The moment I do this and refresh my Hotmail browser, the MSN Hotmail logo changes to Microsoft Office Live Mail.
I am sure many of you who have Office Live accounts associated with you passport account you might have faced this problem (you can call it a “bug” though). The problem here is the “cookie” which is shared by Passport and Office Live to associate the accounts.
If I just log out of Office Live, and refresh the Hotmail page, I will get my MSN HOTMAIL logo back, also if I delete my cookies and refresh the Hotmail browser, MSN HOTMAIL logo comes back.
This looks like a bug which the Office Live team might be aware of and will get fixed in future releases of Office Live.
