Starting recently, when I go to my Office 365 login page using most current ie11, it logs me into my Office 365 without prompting me for my e-mail and password. When I sign-out I get error: "Hmm... we're having trouble signing you out. You may still be signed in to some applications. Close your browser to finish signing out." When I close my browser and login again, same result -- automatically logged in.
I do not want this behavior as I login to many different Office 365 accounts as an IT admin (and generally don't want autologin to online e-mail).
I tried all five methods in above link.
I am certain my cache and cookies and clear.
I removed the credentials for my e-mail from windows crendentials.
I am on most recently-updated version of Win10 Pro.
I don't know where it is storing my password or how to stop this behavior. I want it to prompt me for e-mail and login every time and I want it to sign-out without error.
