I am unable to download email for my Bell email accounts. For one of the two Bell accounts all messages disappeared. I get an error message saying saying the server's certificate is invalid.

We have used mobile.charter,net for our emails since we signed up for your product. Now my husband gets the mobile.charter.net "certificate is not from a trusted source" error when Modzilla is retrieving emails. I have the same email provider, and do not get the error message from Modzilla. Can you help us correct this problem?

Email not working on my desktop. Using Edge 11, Settings show certificate for mobile.charter.net:993 does not come from a trusted source. I can not send or receive email on my desktop. This started this morning. I have not made any changes to my computer, but did do an Edge update. I can check my email on my cellphone if there is a fix.
