I have just changed from Windows Vista to Windows 10 and now Thunderbird will not recognise my email server password. I now cannot get emails to download.

I'm now using Windows 10 and when I attempt to download emails into Thunderbird from the server (iinet) Thunderbird asks for my iinet password. When I put this in it says 'authentification failed'. I haven't changed the password and if I go into iinet I can access all my emails using this password. It seems that, since updating to Windows 10, Thunderbird now doesn't recognise the password and will not allow the email download. When I checked the stored passwords in the Security section Thunderbird says there aren't any. Do I need to set everything up again? If so, how do I do this?

If you cannot receive nor send then your Firewall maybe blocking Thunderbird. Close thunderbird. Access the 'Firewall' program and reset Thunderbird as an allowed program.

Are you using something like CCleaner ? Do not allow CCleaner access to Thunderbird folders. It is possible CCleaner has erased passwords. Recently, there are reports of CCLeaner being responsible for removing the 'prefs.js' file.
