Email not working at all for 24 hours

Thanks - just got emails flowing again directly within my overall xfinity account.  Now can't get them going again in my outlook

i never did change anything in the outlook account after updating my xfinity password - would that make a difference? 

Also I never changed anything in Outlook after updating my xfinity password - do i need to change something in outlook now? 

Definitely as you will need to go into your Outlook settings and update your information within that application.
