It seems strange that I can be signed into the Forums in IE and bring up Outlook in a new window it signs in I suppose due to cookies.
I have IE to delete all upon closing (cookies, etc).
Yet if I bring up Outlook in IE and sign into it then bring up Forums in IE I am not signed into Forums. However if I select the sign in selection in Forums window it will then sign in using cookies already signed into Outlook I suppose.
Of course this has been happening since I joined Microsoft in May 2012.
