Access your Firewall which may be part of your Anti-Virus product and make sure Thunderbird is an allowed program.

Do I understand correctly, that you are using a Windows XP operating system? What version of Thunderbird did you install ? Please post the link where you got the download from.

Please post the following info: In Thunderbird

• Help > Troubleshooting Information
• Do Not select checkbox to include account names
• click on 'Copy text to clipboard' button
• Then in this forum question, right click in a 'Post a reply' text box and select 'Paste'.

Hi

Thank you for your reply.

I've checked the firewalls, and yes, Thunderbird is an allowed program for both the Windows and Norton firewalls.

Yes I'm using Windows XP SP3.

I downloaded Thunderbird from https://www.thunderbird.net/en-US/

It's version 38.5.0

I'll post the info you requested in Thunderbird.

Correction: version 45.80 has just auto downloaded.

Access webmail account. Verify that there are new messages, not previously downloaded and they are in the Inbox folder. Pop mail accounts can only access the server Inbox folder and download from the Inbox.

re :I've checked the firewalls, and yes, Thunderbird is an allowed program for both the Windows and Norton firewalls.

Please note that you should only allow one Firewall to be operating. Conflicts can occur if both are running at the same time. In your case, I would suggest use Norton and switch off Windows.

Note: It has been known that Norton can get confused about a newer version of Thunderbird being entirely different from the older version. The best way to check is to exit Thunderbird first, then access Norton firewall, block Thunderbird, ok it and then access again and allow it. then start Thunderbird.

Check your settings in Thunderbird.

• Right click on mail account name in Folder Pane and select 'Settings'
• Select 'Server Settings'

• Username = full email address

• select 'Check for new messages at start up'
• select: 'Check for new messages every eg: 20 minutes'
• Select: 'Automatically download new messages'

If you want to keep a copy on the server:

• Select 'Leave messages on server'
• click on 'OK'

Restart Thunderbird.

It should auto try to access server.

What do you see in the bottom Status Bar: eg: Looking up server, login, trying to connect, connecting ?

Do you get an error message ? If yes, what does it say, word for word ?

I also notice you are using a different server name for outgoing messages. eg :mail42.extendcp.co.uk According to the help pages, it should have the same name as the incoming server. https://www.heartinternet.uk/support/article/how-do-i-set-up-a-mailbox-using-pop3-on-my-device-or-mail-client.html

At the following link, under the comments section at the bottom, someone asks about SSL. https://www.heartinternet.uk/blog/how-do-i-check-my-email-part-one-hosted-email-on-windows-10-mail/

The response mentions using the server’s generic hostname, which is what you have done in the outgoing server name, but they also state this uses SSL.

Hi

Thank you again for your help.

I think I've discovered the solution, and it's something very obvious I should have realised. it was when I read your words "Pop mail accounts can only access the server Inbox folder and download from the Inbox."

I've been running OE6 and Thunderbird at the same time. If I open OE6, it downloads any new messages from the server, so if I then open Thunderbird there's nothing left to download!

I closed OE6, sent a test message from another email address, and it arrived in Thunderbird!

So the problem appears to be solved.

Thanks again

Dan
