Issues sending email in Outlook after updating password

Need some assistance with being able to send emails after updating password through web interface. Have tried to put the updated password into Outlook (Classic) and am prompted to enter the user name and password.  Entering the new password has no effect for sending, but I am receiving new emails.  Need a Comcast agent's help.

If you can take a peek at the outgoing server settings. That should resolve the sending issue. 
  • Outgoing Mail Server Name: smtp.comcast.net
  • Outgoing Mail Server Port Number: 587 (SMTP)
  • Encryption: TLS (use SSL if TLS isn't shown)

Same issue. Even tried another third-party email app as well and more or less experience the same issue too. Fix posted by XfinityThomasB did not work.

A massive ordeal for those of us who use our Xfinity email address regularly. Please provide a real fix or do better, Xfinity. This is how you lose customers.

Hi user_84o0g4, thank you for coming to our Forum for support with your email issues. With the way I use my email, I can only imagine what you've been going through. I would like to get on the same page and work on finding a resolution with you. Are you able to test the Xfinity website to see if you're able to sign in and send emails there?

Having same issue today.  Received error message on Outlook 365 on my desktop that password is not correct.  Went to Xfinity to login to Comcast email.  Xfinity required a new password to my Comcast email.  Successfully changed the password and logged in to Comcast email on Xfinity website on my desktop.  Returned to Outlook 365 mail on desktop and updated password to match/sync with Xfinity/Comcast email website.  New password for Outlook 365 would not work.  Can only receive Outlook emails, but not able to send.  Tried several of the Xfinity suggested changes to get Outlook to work correctly, but no luck.  Is this an Xfinity/Comcast system issue that is impacting other Outlook desktop users?   Is there a system fix for this?
