Wife and I both have comcast accounts, but when she sends to me I don't get the mail. I'm using outlook 2010 setup as POP. Also when I check online it's not there either. I've resent and verified it was sent several time. And yes I've checked all the folders!
Disable the account in Outlook. Then as a test, have your wife send an email to you. Does it then appear in your Inbox in the webmail UI?
Yes did get the email but took 3 hours to arrive in xfinity mail webpage/app. The I opened outlook 2010 and downloaded OK. The email wife sent was a forwarded mail which sent 5 times and I only got 2.
