I am running Thunderbird 31.5.0 on Windows 7. When I open the program everything is normal but when I try to check my mail it is unable to connect to my server. I have contacted my mail server and they say everything is good on their end. I can access my mail by web mail. They gave me settings to check in Thunderbird for the incoming server and port but when I go to tools/account settings/server settings/account actions/create a new account, then "get a new account", I get the error message "Sorry - we're unable to communicate with our sign-up server. Please check your connection." When I try the "use my existing e-mail" button and fill in the information for my existing account and hit continue the next page appears with the error message "! Thunderbird failed to find the settings for your e-mail account." Everything was working normally until I loaded the latest update last week. I run Thunderbird on multiple computers and I am having this problem on all of them even though I only ran the update on one. How can I check and possibly edit my existing account's server settings? Or is this problem located somewhere else?
