About week ago I received the last email into my hotmail inbox in Outlook 2016 (Win 10).
Hotmail account is not default, I have my ISP email account setup as default.

Outlook status is always "Trying to connect" which refers to hotmail as my ISP account works without problems.
I need to add I am using this setup for 4 years or longer and this is the first time I got the problem.

Connecting to hotmail is not a problem via web browsers so it is not that I forgot my password. (It is microsoft live credentials as well).

Did anyone see anything like that and can suggest a fix?
