What do you mean by " they do not support windows mail at Thunderbird"? Thunderbird is a different email application, created by Mozilla, (the creators of the Firefox browser), and Microsoft has nothing to do with Thunderbird. So, what did you mean by that?
Is your email provided by Sky? What I mean is, is Sky your ISP, (Internet Service Provider), and have they supplied you with an email address?
If so, then this statement that "Sky does not support Windows Live Mail" is very misleading. Windows Live Mail is just an email application, the same as Thunderbird, and any other email software you may have installed on your computer. So it matters not to Sky what email software, (commonly called 'email client'), you use. As long as it is set up correctly, then Sky are unconcerned.
It 'may be' that Sky are saying they have no technical knowledge of WLM, and no-one available to help you with it, so they don't "support" problems with WLM.
Here's a test for you. Does Sky allow you to access your email account on its web site? Most ISPs do this now. If so,
1] Goto your Sky ISPs web site and login to your account. It may be shown as your account or your email account, or your Sky account. I can't say.
2] Use the username and password that you normally use to log in to your email server with WLM. If Sky reset the password recently, try that. Often the username is your full email address, but different ISPs have different systems.
3] If you can successfully login and see your emails in the browser, then your password is fine.
4] If that's the case, then it is likely Sky is having problems with its POP and SMTP email servers, and that is up to them to sort out.
Finally, search Sky's ISP web site for a "Service Status" page and look at that. See if they are reporting problems with their email servers at the moment.
Just to explain, web site access for email is different to WLM (or Thunderbird) access, and one may work when the other doesn't.
If you can access web mail, then it's back to Sky to report a fault with their email servers.
