I am unable to receive comcast email using outlook 2007 using my new Verizon MIFI4620L Jetpack. When I disconnect from the Jetpack, I am able to receive emails using my neighbor's wireless router. I am able to send email using the MIFI Jetpack. When I test email settings, I am able to connect to comcast and send a test email. I am able to receive the test email from Microsoft. I am able to access email using the internet at comcast.net and I am able to use web browsers using the Mifi device. My other laptop is able to receive and send emails using the MIFI device. I currently have uninstalled Norton Internet Security and disabled windows firewall on the problematic computer in an attempt to resolve this.
There seems to be alot of Comcast email issues with the MiFi 4620L. Most of them have been resolved with the propper configuration. We have already found a few limitations to certain websites with this device, but none have been confirmed to be related to email services so far.

See if a quick configuration check will resolve your issues from the links I have provided. If not then the next best step may be reinstalling Outlook on your computer. Keep us posted either way.
