Thunderbird won't download new messages

more options

IMAP is set up correctly and Thunderbird plays sound notification when a new message is available despite: - not showing the dialog notification - not downloading the message itself - not updating the number of unread messages

Other accounts work just fine. Sending messages with this account works. It happened after a fresh install of Thunderbird. Avast is installed on my computer, I disabled it for 10 minutes but nothing changed.

As per your Troubleshooting Information there are three IMAP accounts. Which is the one showing the problem?

Avast is installed on my computer,

As per your Troubleshooting Information your anti-virus software is Windows Defender. Please clarify.

The last one is showing the problem.

I installed Avast. Windows Defender is installed by default with Windows 10.

I'm afraid I still don't really understand your problem.

Thunderbird plays sound notification when a new message is available

What do you mean with 'available'? The new message notification doesn't trigger when a new message is 'available' on the server. It is triggered when Thunderbird has received the message.

despite: - not showing the dialog notification

What dialog?

- not downloading the message itself -

How do you determine the message has not been downloaded, assuming there is a new message in the first place.

So basically are you saying there is some sort of sound notification, and you're assuming that this would indicate a new message has been received by Thunderbird? But then there is no evidence a new message has actually been received? Have you checked via webmail a new message is present on the server?

I installed Avast.

I do not doubt that. The question is which anti-virus software is actually active? There must only be one active real-time scanner, and Thunderbird indicates that this is Windows Defender.

Try to create an exception in Defender for the Thunderbird profile folder. http://kb.mozillazine.org/Profile_folder_-_Thunderbird

more options

Thunderbird : - plays the sound of a new downloaded/"available" message - the email address becomes blue on the left side of the window (where all the accounts are listed)

However: - the "Reception folder" does not change its number of unread message (written in parenthesis) - there is no notification message on the lower right corner of my screen - there is no new message downloaded in the folder despite THERE IS ONE on the webmail interface

The only thing enabled in my Windows Defender configuration is the Firewall in which Thunderbird is allowed.

more options

This all sounds very odd, and I'm not sure what else to suggest.

You can try to create a new profile using profile manager. https://support.mozilla.org/kb/using-multiple-profiles

Then start Thunderbird with the new profile also using profile manager.

Set up the troubled account in the new profile.

Do you still see the problem?

more options

Yes, I still see the problem. I found other people on a French forum having the same issue discribed with laposte.net provider.

more options

Then you should contact your email provider.
