Outlook desktop app is still unable to connect to Outlook.com

**UPDATE** - by X'ing out the popup Windows Security box several times, eventually, the account was added to my Outlook 2016 app on my work computer. That said, the account was added as an IMAP account, and only my email appears to be showing in the Outlook 2016 app. I do not have the associated personal use calendar listed under "My Calendars" to select and overlay with my work calendar. Before this issue, I could overlay my work and personal Outlook account for years. 

I also have NONE of my contacts from my personal account showing in Outlook 2016 on my work computer. I keep all my contacts personal/work in my personal so they can move with me from job to job.

I have been experiencing an issue with my desktop Outlook 2016 app, which won't accept my credentials for the email from my Microsoft 365 Family account. 

This was a known issue that looks as though it was resolved yesterday. 

Outlook and other apps are unable to connect to Outlook.com - Microsoft Support

I am trying to add this account. I have turned on 2-step verification and turned off passcodes. When adding the account, I get a box asking for my name, email address, and passcode. I am generating an app password to use at sign-in. The box shows that the program is stuck at "Searching for (email address) settings," a Windows Security box has popped up asking again for my password. I have entered the generated app passcode there, and that window disappears and pops up again, seemingly like the issue has not been resolved. 

Thank you.
