How do I remove suggested accounts from outlook?

When I click on a hyperlink on a website which takes me through to email automatically, i am brought to the outlook page. If i then go to accounts > add account there is suggested email addresses there.

Even having deleted them using the prompts, they are still there in the suggested emails and can be signed in with one click without having to enter a password, which is a major security risk.

How can I actually delete them? I have tried changing my password on the suggested email but alarmingly, the suggested email problem I'm describing above bypassed entering the new password and logged in automatically.

I have also tried clearing cache in outlook and google chrome and nothing has worked.
