Windows 10: IE11 Login to OneDrive persists after deleting cookies etc...

I think this is a new bug.
I have Win10 ver 1703 Build 15063.413. I have several Microsoft accounts for separate purposes. I'm discovering that unlike in the past, IE11 is maintaining a cookie o some other mean of login despite my efforts to both logout AND delete cookies & temp files. after clearing via 'internet optons' menu in IE I close the app.
when I rerun, and browse to onedrive.com [clean], I'm immediately logged in to the same account I signed out of.
when I then sign-out again, it appears to do so & takes me to a different ms page. but open another tab and fresh-type 'onedrive.com' hit enter I'm right back where I signed out of.

any ideas on how to truly cleanup?
I can work around it by using Opera or Privvy mode of IE11 but I would rather it do as I command it.

edge website visits cache in ie11 when invoked from outlook 2016

When accessing a link in a Outlook 2016 email, the site opens in Edge(the default browser). The Cookies are cached in IE 11, which is set to delete history on exit and is not checked for ":Allow caches and databases" Cookies and other files in IE 11
from Outlook/Edge sessions remain after IE11 opens and closes. Deleting files in Edge do not effect the files left in IE11 caches.

 

Internet Explorer 11 degrading after Windows 10 Update

Hi Guru, Thanks for your reply

I have deleted browsing history and cookies. When started without add-ons IE11 shows no improvement.

The page is displayed after 20 seconds. IE11 then freezes and returns control to me after another 30 seconds.

 

bump please. Found out it isn't just Onedrive. Cannot get IE11 to clear cookies/login data. corrupt folder maybe? where are these stored?
