tried what was suggest - still "Login to server pop.freeserve.co.uk failed". I can see my mail on the web based server.

Is that the entire error message?

message1: Sending of password for user **********.freeserve.co.uk did not succeed. Mail server pop.freeserve.co.uk responded: Invalid login or password

click ok

message2: Login to server pop.freeserve.co.uk failed.

options: retry - enter new password - cancel

thanks

Have you checked with your email provider whether they do have any problems?

You can verify your credentials via webmail.

hi there,

i have, they have no problems. i can send and receive email through their webmail for the same account. they said issues were with Thunderbird and suggested removing and then re-adding the program but i think this has happened with the Thunderbird update therefore thought that i would be adding the same version? thank you for your support.

Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 8, Windows 7, Windows Vista, Windows XP, OSX

If safe mode for the operating system fixes the issue, there's other software in your computer that's causing problems. Possibilities include but not limited to: AV scanning, virus/malware, background downloads such as program updates.
