Only with the webmail interface and one of the three browsers...Google Chrome, Mozilla Firefox, or Internet Explorer. I have no email client loaded.
Then I'm going to escalate this to the forum admins for follow-up. I've never encountered this phenomena with the webmail before in the forums. You should see a response here in this thread.

I have not heard back from you, "Comcast Employee." I am still having the problem. What is the solution?
Did you send the PM as requested by the employee?

Yes. scroll up in the posting string and you will see the "Comcast Employee" request for a PM on November 1st. I sent it that day and I HAVE NOT HEARD FROM him/her/them. ??????
OK then I'll escalate it again and see if we can get some traction for you.

I have a similar issue: I receive duplicate emails (not every email but several/day). I'm not seeing a pattern (same sender, size, etc.). Often the second version appears one-two minutes later than the first. Any suggestions? Obviously i just delete the duplicate, but it seems inefficient.
Thank you.
Are you using a desktop email client like Outlook or Thunderbird? Or the Mail app on a mobile device? Or just the webmail with a browser?

This problem went away and now it's back. 
It would be helpful if someone at Comcast could put some cycles into this.
Here are the most interesting headers at the origination of a pair of these duplicate messages.
Looks like Open Exchange is the mailer used in webmail? It appears that a single message is created and sent (Date header), but then 2 separate copies of that are being sent forward as separate messages 1 second apart to different next-hop relays.

Somebody was kind enough to give me kudos for that last post. I got 2 copies of the email telling me that.
