Hi again,

I forgot to say that I get a pop-up message saying something like "' you may have exceeded the number of connections to the server". The message appears for 1 second and is not in the error console.

Thanks for your help.

Hello charlotteauxfraises, You may wish to provide more detail if you want community help. For example, are you using a Mac OS or Windows? And are you using an IMAP or POP Gmail account?

Regarding the pop-up error message you saw for 1 second--I think this is usually an issue only for IMAP accounts, so I am guessing you are using IMAP. There is a suggested fix here: http://www.electrictoolbox.com/thunderbird-exceeded-maximum-connections-imap-server/ . Try it and see if it works.

If it doesn't help (or if you have a POP account) then you should check to see that your configuration is correct, both in gmail, and in Thunderbird. I understand these problems have started even though you haven't changed anything in your account settings, but it's a good idea, as a starting point, to make sure your port settings, connection security settings, authentication method, etc. are all correct.

Follow the directions at https://support.google.com/mail/troubleshooter/1668960?hl=en#ts=1665119,1665160 and see if you are set up correctly.

Hope this helps, Norio

Hi Norio,

Many thanks for your reply. Indeed as i mentioned in the title I am using two IMAP accounts : Gmail and Outlook. I am under Windows 7 . Firefox is my browser and TB my mail "supplier". I do not have anything strange installed on my computer and is using TB&FF for many years already. My firewall is avast.

Following you advise I put the connections to servers to "1 "but this did not help. I also checked my accounts settings but everything is all right.

Still I do not get my mail in TB.

I wish I would not have updated to 38.0.1 !

I hope that the the mozzilla community can soon find a solution.

Charlotte,

I do not know kind of miracle happened. TB works again fine. Thanks to all for the hard work.
