Using classic Outlook for Windows in business environments
>> The email account is still managed through Microsoft's admin portal.
Here's what I got from a similar discussion thread:
Exchange admin is done on Microsoft's portal (including GoDaddy customers): https://admin.exchange.microsoft.com
but the 365 admin portal (https://admin.microsoft.com) redirects to GoDaddy management site. As for the details... I have no clue because I have never had GoDaddy mail hosting service. He mentioned his IT personnel skill isn't up to par (IT is fairly amateur level).) so asking for GoDaddy help seems logical to me.
