Wow I am so mad? Went to go download emails on a USB for my friend of our conversation a couple years ago and they are deleted. I know for a fact that I didn't delete them so clearly this company deleted them themselves. Also, it is ridiculous that there is no way to even retireve them? Not in the recover deleted items section either because it didn't keep them. I am so unbelievably disappointed that such a well known company with a good name is actually horrible and su cks and doesn't offer any way to help. I hate xfinity and comcast now. I will never use them as a provider again.
Comcast doesn't delete emails. Do you have the account enabled on another device using POP3? If so the messages may have been downloaded and then deleted from the server.
