I also have the same issue. Started last week and I have spent hours trying to fix it. Did delete the email account but now I can't get Outlook to see the account -- it tries to pair with Spectrum and then says "try again later. You might need an app password". Checked all over Spectrum website but nowhere is there anything about an app password - just your regular password. Back to Microsoft who says "spectrum's fault'. Nope. I will do as others have said and check my email on my phone and hope.
Come on Microsoft!!
