I never really got a straight answer out of Comcast and they finally stopped calling me back so I ended up finally fixing the problem On My Own by changing my IP address via a video I found on YouTube. Apparently Comcast has a lot of issues with with their SMPT servers blocking emails. They will accidentally are inadvertently block a users IP address just due to server errors in that appears to be what happened in my case. The only way to undo this that I found is to change your IP address which requires going through your router and kind of resetting it... It is a pain in the butt sort of but nowhere near as much of a hassle is getting the runaround from 8 different Comcast employees and having to reinstall a bunch of software that doesn't really do anything to fix the problem. If I had a nickel for every time they asked me to delete and reinstall the Xfinity contact app and then reset up all my signatures and so forth ...... Long story short, you are better off trying to figure out how to solve it on your own or contacting a real IS person for a serious solution rather than just wasting time on the phone with Comcast. Most of the folks just have a script to read and no where in the script does it allow them to admit anything being a Comcast's issue which most of the time it actually is....

Cannot send outgoing email from Comcast email address via Xfinity App or Outlook via cable internet wifi
But I CAN Send them fine from OUTLOOK and APP if I am on Cellular DATA network
On my Wifi (medicom cable connection) using the Xfinity Connect APP -Incoming messages are fine but Cannot send emails starting this morning, incoming emails are fine. Get error message that says :
Xfinity Mobile encountered an error. Please try again later. Message moved to draft.
If I take my phone OFF wi-fi and just use Mobile Data, the outgoing messages go though and no error message.
Also am having issues sending from outlook on my laptop, get two different error messages - one is a Server responded 421 resomta-po- 11v.sys.com when I try o test from outlook settings. Other is Sending ' reported error (0x800ccc67) :'The server responded: then a bunch of funny characters...
Incoming emails are fine. This just started this am. I did not change anything on my end. If I connect to a HOT SPOT with my cellular plan- everything works fine. Talked to three diffrent folks at comcast, "help," line and all said I should just keep on re-installing apps and software until I am blue in the face since they have neither the ability nor inclination to offer any real assistance in this matter...Everything works fine on Cellular data -there just appears to be some sort of conflict with the outgoing SMPT server and my cable internet wifi that wans't an issue until this morning. I did try removing my firewall on my internet secuirty program and that didn't help.

For quite a while now it seems like many users are having issues with the Connect app not loading emails like it used to about a year ago. The emails take forever to load and cannot be opened or deleted until they are fully loaded which can take a minute or two. I see a bunch of people inquiring about this issue with all different kinds of phones and the answer seems to always be reinstall the app which clearly doesn't fix the problem unless you guys have a new app version that I don't know about. Before I waste my time and energy reloading the app can you tell me if there have been any improvements that correct this issue? It is a huge hassle in it is unfortunate that is taking so long to get it corrected. Are you even working on a correction or should I just try to move to a different email app?? This was a really nice app before that issue started and it would be nice if I could go back to functioning properly but taking one to two minutes to load emails is just not going to work and I'm not going to reload it every day to try to deal with programming issues.
