Outlook.com Mail

FINALLY received the transition to Outlook.com to Outlook Mail for my personal hotmail.com account. It looks nice. I added my FIOS and Gmail accounts to it and that seems to work well.

I wanted to add another outlook.com but that didnt work – it asked me to manually setup so I followed the instructions at https://support.office.com/en-us/article/Add-your-Outlook-com-account-to-another-mail-app-73f3b178-0009-41ae-aab1-87b80fa94970 under “Apps that support POP and IMAP” to set up an imap account, but that too failed. How can I add a second microsoft cloud email account to an outlook.com instance?
