So I successfully set up one business email address through my Office 365 account. I've logged in, sent and received email, all is well. I then established a second email address, waited to get the confirmation email from GoDaddy, then when I did I followed the link back to my Outlook inbox, which I noticed linked me to my first email address. I clicked on the account icon and then clicked Open Another Email Inbox, then when I started typing the new email address it auto-populated the new name (great news!) but then it tells me I don't have permission to access that account. What step did I miss? Using a MacBook if that matters. Thanks for any help.
