Email Problems

Hello,we are having issues downloading emails into Thunderbird. When we open Thunderbird I see a message that says " Connecting to imap.comcast.net" but nothing downloads. If I power off or reset the cable modem that we get email for a day or so than it stops again until I repeat the rest process. This has been going on for a long time now and I have contacted the on-line support with no luck. I tried switching over to Outlook but the same issue occurs. Any suggestions would be appreciated.

Thanks for taking the time to reach out to us through our business forums. I am so sorry for the delay in our response. I know how important Email can be to a business and I want to do all that I can to ensure that we get to the bottom of this with you. Can you please reach out through private message with your first and last name, full service address and account number or phone number?
