I have installed Thunderbird and have been very pleased with it. I only use
Thunderbird at the moment to keep all my RSS feeds that I use.

I still use IE as my default browser but the problem I have now is trying to
send a URL via email through the IE. On IE if you go to FileSendLink by
Email it always launches Thunderbird. I do not want this to happen, I want
it to launch Outlook as it normally did. I have reset the settings in
Internet options to their default and it still makes no difference. I do
not use Thunderbird as my default mail client.

Any ideas how to get Outlook to launch when I choose the option in IE?
