I've been using Thunderbird on a Windows machine for years. I now have an iMac and recently downloaded Thunderbird to start transitioning over. When I try to set up an existing Email address, the configuration is found in the Mozilla ISP database. After I enter the password though (mobile.charter.net), I get an error stating "Unable to log in at server. Probably wrong configuration, username or password". The password is correct and works on the Thunderbird version on the Windows machine. I have multiple Email addresses and I get the same error on all with verified correct passwords. Any help to correctly install would be greatly appreciated!

Hi I am using Win 10 and update 140. I updated yesterday.

I have been unable to rebuild my Inbox after doing an Inbox repair. It is having trouble staying connected to my email server, imap.comcast.net. The lower left message continually shifts from Sending Login Info, to Connecting to imap.comcast.net, to Connected, to Opening Inbox folder to looking up imap.comcast.net.

I repaired the inbox because all of a sudden I could not open new messages. I would click on them and it would say loading message but remain blank.

I have also had periodic problems with network and file errors. Just before this happened, I could send a message but not copy it to my Sent folder because of these errors.

If I uninstalled and reinstalled Thunderbird would it go back to the way it was?

Should I do a system restore?

By the way I am connected online and at a high speed. so that is not the problem

Thank you Richard Higgins Concord MA

I've been trying to connect now for 12 hours and have only recovered a fraction

Hello All,

After 7 years Thunderbird is no longer working with my comcast email address. I know this is probably a comcast issue but after more then a week trying to get any sort of help from them I have given up on Comcast and turned here hoping this is some simple issue that someone has seen.

Comcast webmail access works fine

Via Thunderbird - I can send a message although it will not make a copy of the sent message and long after the message is actually sent I am looking at a message in TB that says 'Connecting to imap.comcast.net, which eventually times out telling me it cannot make a copy of the message.

I receive no messages at all

Nothing has changed on my end of the configuration

Any insight or ideas would be appreciated.

My basic Server Settings Are imap.comcast.net Port 995 SSL/TLS Normal Password

Thank you.

Hi,

today Thunderbird doesnt send nor discharge emails from gmail. I've seen that yesterday (december 10) it was an update. I dont know it the problem it's related or not, but the program doesnt work, it seems that it tries to connect with server but it cant. If I send an email from Gmail page it works.

Thanks for your help miquel arderiu

I then click on cancel to get it off my email screen. However it continues to pop up whenever I try to get my email, even though the mail comes through, it says can not connect to server. Very confusing. Anyone have this issue?
