I use a hotmail account several years with outlook but today a password request dialog suddenly jumps out.
when i tried to input the account info, this red line shows out "You can't sign in here with a personal account. Use your work or school account instead."
The same account could be signed in by web(chrome, edge, ie) and skype.
Changing password has no use.
delete the old profile of outlook and create new one has no effect.
even trying to add this email account to a new installed system display same error.
Further more, i have one other hotmail account and that one is working perfectly.
such issue only occurs on one specific account.
I have neither office 365 nor other business services subscribed.
