Hi billvau,
Does this issue only occur to the yahoo account?
Can you add other email accounts properly?
>> Outlook asks for my password like 20x and then tells me it's my problem and go see my mail administrator.
Could you please provide the detailed error message then we can do further research on this?
Besides, please refer to the Yahoo section in the following article for detailed instructions about adding your Yahoo account to Outlook 2016:

Any updates, please feel free to post back.
Best regards,
Yuki Sun
