Can you take a look at this question?

Thanks for your quick response. I have a pop email account. Clearing the cache didn't work.

Do you use any anti-virus or other security software? Disable it entirely and reboot to see what happens then. If sending/receiving works, the issue is in that software so you may need to reconfigure it for Thunderbird.

I turned my anti-virus and firewall off and sending/receiving still does not work.

re :I turned my anti-virus and firewall off If you use a product such as 'Norton' which also controls the Firewall, switching it off may have switched on the default for computer so it will not prove anything.

You need to make sure that the Firewall allows Thunderbird in it's list.

Try: Start Computer in 'Safe mode with Networking' then start thunderbird - report back on results.

Still can't receive nor send emails.

Please provide feedback to any suggestions given above, or we won’t know what you did and did not otherwise.

- How many accounts do you have, and for what email provider(s) does the issue occur? - Do you see an error message? - Do you see anything interesting if you open the Tools menu (press Alt when not visible) > Developer Tools > Error Console, or Tools > Activity Manager? - Do the connections time out silently with no warning/message/logs? - Is Thunderbird set up to use a proxy with "Use this proxy server for all protocols" checked? - Does the page load when opening the Add-ons Manager > Get Add-ons or Help > What’s New?

You could try adding the same provider as a second account in Thunderbird if you have one and see what happens then.

Also, you could enable Logging to see how Thunderbird and the server communicate. Then again, this is troublehooting that I would prefer and perform myself and the above does not help. If you want a quick solution, it may be best to stick to 52.2.1 for now, or use the restore point.

Please let us know what your finding and thoughts are.

- I have 1 account, provider is www.infopact.nl - When I start Thunderbird, at the bottom of the window I see: xxx@ipact.nl: Connecting to pop.ipact.nl

(Note that I have a Dutch version, so this is my translation). The message does not disappear, nor do I see a warning/message.

When I try to send a message, I get an error message (my translation):

Sending the message failed. The message could not be sent, because connecting to outgoing (SMTP-)server smpt.ipact.nl failed. Possibly this server is unavailable or refuses SMTP connections. Check of outgoing (SMTP-)server settings are correct and try again.

As I said in an earlier post, the same happens when in Windows 7 safe mode with network connections.

-Question: where can I see if "Use this proxy server for all protocols" is checked? I can't find that option.

- Get Add-ons or What's New does NOT load the page. Some messsages in the error console: 1504119275691 addons.repository WARN Search failed when repopulating cache 1504119275909 addons.update-checker WARN HTTP Request failed fo an unknown reason

despite my inability to speak anything but english. This page looks to use server names very different from those in your account settings.

While the information is for outlook, the server names and port for Thunderbird and outlook are the same.

Check Tools (press Alt when needed) OR use the Menu button/hamburger icon > Options > Advanced panel > Network & Disk Space tab > Settings button, make sure to select "No proxy".

Apparently all your connections are blocked, both for POP and HTTP access. This could happen when that proxy setting is checked and any proxy cannot handle email port traffic or is not present, or security / antivirus software is interfering. The latter should not be the case, and if this helps, I wonder why it did not affect the previous version.

Sorry, but It doesn't help. Settings are entirely identical to what I used in the previous Thunderbird version.

Those 'allesin1' settings are not correct for me. All my settings are identical to what I used in the previous Thunderbird version (and worked when I went back to that version). I also tried them in eM Client (http://emclient.com/) and there they work. I prefer Thunderbird though.

Create a new Thunderbird profile (as a test) and launch Thunderbird with that profile, ignore the account setup, see if you can load the What’s New page and check what the "Check for updates button" reports, then report the Error Console server log here if it fails. The page should load and if not, something is messing up your connection and it is not realated to your setup/profile.

Also try to disable antivirus / security software and reboot - just disabling often is not enough. You could even uninstall it temporarily. Does it happen to be Kaspersky or Avast? This may be a certificate issue.

As you reported the issue to have started after the update to 52.3, you could also (safely) uninstall 52.3 and install 52.2.1 instead. For some reason I cannot imagine this to have started in 52.3.0, or in other words: what more has happened after the restore point was created? And what version did you update Thunderbird from? (Check the Update History in the Options > Advanced panel > Update tab.)

Ok, I missed that nothing was working. Are you using Norton anti virus, or another of those security products with an application firewall. Check it allows the newer version of Thunderbird. We often see folks having issues with connectivity caused by firewall in security products

I de-installed 52.3 and went back to 52.2.1 (that is the version I updated from). Since that version works (with the same connection settings), I will stick with it for the time being. Thanks for your efforts!

Sorry to see, but your choice.

Remember that you will likely run into the same issue at the next Thunderbird update. You did not provide us with info about what security / antivirus software you were using, but most likely this is the root of the issue.

Sorry to see, but your choice. Remember that you will likely run into the same issue at the next Thunderbird update. You did not provide us with info about what security / antivirus software you were using, but most likely this is the root of the issue.

I use Avast antivirus and ZoneAlarm firewall. But in safe mode these are not running and I still cannot connect.

Avast, as with most other antivirus software, can cause issues. See here for some known ones.

My suspicion however is ZoneAlarm, as that’ the firewall software and caused more connectivity related issues with either Thunderbird or Firefox in the past. Most likely, it just does not update the new Thunderbird version to be recognized as a trusted application.

I’m not sure if you tried removing and re-adding Thunderbird as a trusted application manually, but you could try doing so after first making sure ZoneAlarm is up to date, then updating Thunderbird to 52.3.0, and then see if (ZA failed again and) the issue persists. If that still fails, uninstall ZoneAlarm and if that fails, uninstall Avast. Don’t forget to reboot after each uninstall.

I know you started Windows in Safe Mode but as suggested earlier, you might need to perform a total uninstall of any firewall/security software.

Feel free to leave things as they are, but you will probably understand it would help others.
