Richard recently checked his Outlook/Comcast email and it's now requiring a new user name and password. He hasn't input it in a long time and can't remember it. Leo says that it should be the same password as logging into Richard's Comcast account to get his webmail. Outlook can lose its settings from time to time, especially after being updated. So it may be that Richard just has to re-input the Comcast user name and password. But he may also need to input the mail settings. Google "How to setup Comcast Mail with Outlook." XFinity.com has several pages, based on the version of Outlook you're using. Follow the instructions step by step.
