Can not connect to Incoming imap server to receive emails in Outlook

I have chatted twice with agents online and all I am told is that there is a problem and they are working on it. First it was give it 24 hours. I did...Outlook did connect once and I got a couple of emails...this was yesterday. This morning we once again return to not being able to download new emails into Outlook. Now I am told give it 4 more hours or call in for support. Calling requires sitting on HOLD for almost an hour. There is ZERO communication from Xfinity as to what the problem is or when it might be fixed. This all happened after Xfinity REQUIRED me to change my password. What is going on and why is there NOTHING online about what is going on?
