Something that needs fixing in Office 365: sometimes you cannot log out

Microsoft is notorious for asking users to log in multiple times, even when you check “Keep me signed in”.

Now we have the opposite problem. Here I am in Office 365, logged in as the admin user:


I need a break and want to stay secure, so I drop-down the menu top right and choose Sign out:


Lo, I am still signed in:


And no, it is not just a browser cache issue or similar. You can still do administrative tasks.

I have seen references to the bug in Microsoft support forums, so it is known, but unfixed for ages.

I do not publicise this sort of stuff because of any antipathy towards Microsoft. Rather, I do it because it needs to be improved.
