No idea what you have read or done so far. Here are the settings. Add the account. Do not try to change your POP account settings to IMAP. http://customer.comcast.com/help-and-support/internet/email-client-programs-with-xfinity-email/

Get the error "Configuration could not be verified - is the username or password wrong" -

I know it's the right username and password, I've entered it over and over (and even tested it on the comcast website).

Has Comcast converted your account to IMAP. everything I read about this says they have to do the conversion first. Comcast is still only POP in this area so I cannot try it. Incorrect server settings also give the error you are seeing. Make sure they are correct.

I am using these instructions: http://customer.comcast.com/help-and-support/internet/setting-up-thunderbird/

Get the error shown in the attached.

I did contact Comcast support to ensure my account was set to IMAP and was assured that it was.

Also, if I go in and delete all my Thunderbird accounts in the app - what happens to all the emails? Personal folders? When I rebuild do they reappear or ?

Thx.

I cannot get your attachment to open but there is a misprint, in my opinion, in the Comcast article. The text says use IMAP.Comcast.net for outgoing but the example image shows SMTP.Comcast.net. The image would be the correct server name for outgoing.

Right - caught the typo....updated it to smtp.comcast.net before I tried to set-up.

In the directions it shows you that after you enter your info in the first screen you will get a window that advises manual config - I never get that window...it appears that Thunderbird isn't detecting me as a valid email address with Comcast. It says "Thunderbird failed to find the settings for your email account". If you then go through and set-up everything as they have suggested you get the error "configuration could not be verified - is the user name or password wrong" - it isn't I've checked on web sign-in and re-typed it a dozen times.

Here is an article on manual account entry. It mentioned pressing stop or cancel during the auto setup to change your settings. maybe this will help.

I wish I had a better suggestion. I am running out of ideas.

So the stars just aligned ;-)

As I sat here wondering what the heck....I noticed my virus s/w wasn't turned on....not sure why. Anyway, I started a scan just to make sure things were kosher.

Went back to troubleshooting the mail issue and suddenly everything started downloading.

We're good - thanks for hanging with me, much appreciated :-)

Yes!!!
